Chapter 2 Known issues for Switch 8800 V5.01.21 This section describes known issues in the Switch 8800 V5.01.21 software.



2.1. Configuration File Issues after Software Upgrade Because the Command Line Interface (CLI) of some features were changed considerably between release v3.01.xx and release v5.01.20 or v5.01.21, problems could occur when trying to use a v3.01.xx configuration file on a Switch 8800 running v5.01.20 or v5.01.21 software. Before upgrading to v5.01.20/v5.01.21 software, save and backup the current configuration. After the upgrade and the initial reboot, the switch will come up with the default configuration and will not remember the name of the startup configuration file. Issue the command "startup saved-configuration <saved-config-file-name>" to set the old configuration file for the switch to boot with. A second reboot of the switch is required for that configuration file to come up. Be aware that any v3.01.xx commands in the configuration file that have changed will be ignored when the configuration file is read by the v5.01.20/v5.01.21 software. Most of the features have had some level of CLI changes, however, the following features have had significant changes:

• Quality of Service (QoS) • Access Control Lists (ACL) • DHCP relay • RADIUS

If you are having a problem with a feature, refer to the latest configuration guide/command reference.

2.2. Note regarding features in both Release v3.01.xx and Release v5.01.20/v5.01.21 Similar features appear in Switch 8800 Release v3.01.xx and Release v5.01.20/v5.01.21, however, some of the commands have changed dramatically. If you are having a problem with a feature, refer to the latest configuration guide/command reference.

2.3. Unsupported Modules The following modules, which were introduced in the Switch 8800 v3.01.30 release, are not supported by v5.01.20/v5.01.21 software:

3C17542 3Com Switch 8800 Network Monitoring Module 3C17546 3Com Switch 8800 Firewall Module

3CR1754766 3Com Switch 8800 IPsec Module 3C17548 3Com Switch 8800 VPLS Module

2.4. Unsupported Features Any feature that is not included in the documentation – whether or not it is on the Command Line Interface (CLI) is considered unsupported. Additional specific information is included below.



The following features were supported in Release v3.1.3x but are unsupported in Release v5.01.20/v5.01.21:

• Various ARP Commands – see 2.19 ARP.

• MBGP (Multicast BGP) – this would also affect MSDP implementations

• ISIS

• MPLS and related features: • LDP • L3VPNs - MPLS BGP L3VPNs • L2VPNs - VLL (CCC, Kompella and Martini) • Virtual Routing and Forwarding Instances (VRFs) • VPLS

The following features are included in the CLI in the v5.01.20/v5.01.21 release but are not supported:

• MLD Version 2 (Version 1 works – but Version 2 does NOT work.) • MPLS TE (i.e., RSVP) • NAT • OAM

2.5. Multicast Protocol In some cases, multicast traffic is not supported on ports with overlapped VLANs. As a result, some clients will not be able to receive multicast traffic. 3Com recommends that you implement either fully bridged multicast network or a fully routed multicast network across the link.

In the case of multicast MSDP trans-domain networking, the static RP (Rendezvous Point) mode should be configured. Otherwise, RP dynamic switchover will make MSDP unable to send the SA (Source Active) messages across the domains.

If the equivalent routes exist on the upstream and downstream switches, the ASSERT mechanism is not supported, in which case the PIM SM is recommended. Otherwise, many copies of multicast packets will impact the downstream switch upon configuration of PIM DM.

The multicast IP flows in address ranges such as X.0.0.X, X.128.0.X, X.0.1.1 and X.128.1.1 are sent to the CPU for processing as protocol packets. These multicast IP addresses cannot be used as multicast addresses. Otherwise, the entries of these multicast addresses cannot be established normally, which will cause multicast forward failure.

In the case of large traffic, the duplication capability of the Trunk port is only 35 copies. If multicast packets need to be copied to over 35 VLANs from the port, the multicast VLAN is recommended, or packet loss may occur during packet forwarding.

In the PIM DM mode, it is suggested that the number of the multicast flows in the same group and from different sources be no greater than 64. Otherwise, problems will occur when there is no receiver end in the downstream. Some outgoing interfaces in the upstream do not prune, etc.

Until a multicast group is joined by a client the traffic sent from the server will flood out all ports in the vlan in which the server is connected to. 3Com suggests locating the multicast servers on their own vlans to avoid unwanted traffic flooding the network.



2.6. System Management When FTP or TFTP is used to upgrade the Switch 8800 from the boot menu, the file will retain the original filename. The system image filename should not be renamed when the boot menu is used. This issue does not occur when upgrading the device using the CLI.

Flash on the 3C17508 fabric (360Gig) is not large enough to store the v5.01.20/v5.01.21 image. Use the compact flash to store and boot the image and any backup images. The compact flash is sufficient to store multiple images. The 3C17539 fabric (720Gig) on-board flash is large enough to store a primary and backup image.

2.7. High Availability Under some circumstances, a user may experience a short but noticeable network convergence delay when a Switch 8800 fabric switchover occurs. A one-second switchover can be achieved when STP is disabled and RIP routing protocol is enabled.

2.8. Broadcast Storm Control Broadcast Storm Control (BSC) is not supported on 10-gigabit ports for the Switch 8800.

2.9. STP A port with STP disabled will still forward received BPDUs. To prevent flooding of received BPDU’s, enable STP globally and then disable STP per port.

2.10. TFTP TFTP file transfer of v5.01.20/v5.01.21 software may fail using the 3CServer application. It is recommended that customers use another TFTP application for TFTP transfers.

2.11. Boot Code Boot code upgrade on slave switch fabric fails if boot code doesn't exist in local flash. Copy the boot code manually to both switch fabrics.

2.12. CoS For Switch 8800 CoS, there are prioritization issues with lower default port priorities. For untagged packets, if the ingress port user priority corresponds to a lower traffic class than the egress port user priority, the packets will be prioritized according to the egress port priority. This does not affect tagged packets. Untagged packets are classified according to the following algorithm. Traffic class (TC) equals the maximum of the TC associated with the Source Address and the TC associated with the Destination Address. When the Switch 8800 routes traffic over a tagged link, all packets that are not previously marked with a CoS value will have a default value of 3 (Best Effort) applied to them. This only applies to routed traffic. Layer 2 switched-traffic is not manipulated by the Switch 8800.

2.13. Link Aggregation A disconnected port is still displayed as a selected member of a Link Aggregation group.



In previous releases, if the master port (lowest number port in the aggregation) in a link aggregation changed vlans, all ports in the aggregation changed to the new vlan. In v5.01.20/v5.02.21, only the master port changes vlan membership. There are 3 ways to address this:

1. Put all ports in the correct vlan prior to creating the link-aggregation. 2. Put all ports in the correct vlan after creating the link-aggregation. 3. Use the port group functionality after you have created and populated the link-aggregation -

e.g. to port all ports in link-agg group 1 in vlan 3 as access ports use the following commands

a. [SW8800] port-group aggregation 1 <cr> b. [SW8800-port-group-aggregation-1] port access vlan 3 <cr> c. [SW8800-port-group-aggregation-1] quit<cr>

2.14. QoS To ensure accurate traffic policing, CBS and EBS should be at least as large the MTU of the traffic being filtered. 3Com recommends that the CBS and EBS be 2 times the size of the largest packet expected.

On the same port, traffic shaping and WRR (Weighted Round Robin) cannot be enabled simultaneously, or the WRR queue dispatching mode will not function.

The 100Base port can only dispatch 5 queues at one time. If it is required to send packets from over 5 queues, please use the WRR mode. Otherwise, dispatching over 5 queues may result in the situation where the queues with low priorities cannot be dispatched and therefore the packets in them cannot be sent.

The 3C17532 module and 3C17526 module do not support the WRR mode, so do not enable the WRR mode on either the 3C17532 or 3C17526 board. Instead, the SP (Strict-Priority) mode should be used.

2.15. Super VLAN The Super VLAN feature implementation on the Switch 8800 does not allow Layer 3 communication between sub-VLANs by default. This does NOT impact communication from the sub-VLANs out to the network. It only impacts communication between one sub-VLAN and another. To enable Layer 3 communication between sub-VLANs, proxy ARP should be enabled on the sub-VLANs. Try to reduce the number of SubVLANs attached to a SuperVLAN. The more SubVLANs that are attached to a SuperVLAN, the worse its ARP learning capability will be. In the case of a full configuration with 64 SubVLANs, the ARP learning capability will be degraded (2 per second, along with queue overflow).

2.16. Protocol VLAN Upper level Protocol VLAN commands are missing / not working. It is recommended that you use the lower level commands as detailed below.

if ip ARP is desired – should use the command

[SW8800] proto mode ethernetii etype 0806 if Appletalk ARP is desired – should use the command



[SW8800] proto mode ethernetii etype 80F3

[SW8800] proto mode snap etype 80F3 The protocol vlan command “protocol at” does not cover snap encapsulated appletalk packets. If you want to classify snap encapsulated appletalk packets on vlan X use the [SW8800 – vlanX] protocol mode snap etype 809B <cr>

2.17. DHCP Relay Significant changes have been made to the command line interface for this feature. Please refer to the new configuration and command reference manuals for info on setting up this feature.

2.18. RADIUS Significant changes have been made to the command line interface for this feature. Please refer to the new configuration and command reference manuals for info on setting up this feature. If an accounting server is not present – user should set accounting to optional. Otherwise log-in will fail when the accounting server is not found. A super password should be set. When logging in thru RADIUS, the super command may be required to access the full set of system commands.

2.19. ARP Commands that control the following ARP parameters are NOT included in v5.01.20 or v5.01.21. These commands existed in all version 3 releases starting with 3.01.21.

Size of the ARP table.

ARP entries are reserved for Aggregated Links.

ARP entries available on the fabric/chassis.

ARP entries available for single ports.

The ARP table does not show Aging time. A Switch 8800 with all Advanced MX modules (e.g., 3C17531) can learn 8K ARP entries per module and up to 64K ARP entries per chassis. 7 aggregated link groups are supported (max link aggregation for Advanced MX Modules is 7 groups of 8 ports in a system with all Advanced MX Modules).

The Static Multicast ARP Across Modules feature is not included in this release. This feature was included in v3.01.22 and 3.01.31/3.01.32 – not included in 3.01.30 or releases before 3.01.22. Feature supports network load balancing.



2.20. LACP Dynamic LACP has been removed from the v5.01.20/v5.01.21 release. It is recommended that the more deterministic static LACP be used instead. Static LACP allows more customer control over the network configuration.

2.21. Boot Loader When using the boot-loader file (filename or pathname) slot (slot number of the fabric) (main or backup attribute) command without a fully qualified pathname (e.g. cf0:/ or flash:/), the default is not always flash. Example: boot-loader file 88h05_01_21s168rec01.app slot 6 main command would be clearer if entered: boot-loader file cf0:/88h05_01_21s168rec01.app slot 6 main (or cf:/ 88h05_01_21s168rec01.app slot 6 main if using the 5.01.20 release) or boot-loader file flash:/88h05_01_21s168rec01.app slot 6 main. Caution should be taken when specifying a code version. Use the full path name if in doubt. Use the “display boot” command to verify that the correct agent code has been specified.

2.22. ACL The default application order for the ACL rules is configuration order. This means that the rules are applied in the order entered. This can be changed to auto order by using the command ACL number xx match-order auto. In auto order, rules with a smaller range will dominate. For example: a deny rule for a host will dominate over a permit rule for a LAN segment and traffic from that host will be disallowed. In the Ethernet frame header ACLs (numbers 4000 thru 4999), the vlan-id option is no longer available. Depending upon your application, the following features may be able to be used as substitutes:

1. Normal vlan ingress/egress rules. 2. Vlan ACLs 3. QoS policies could be used to classify based on Service Vlan Id (outer vlan tag in the case

of QinQ or the only tag in the case of a normal tagged packet) or Customer Vlan Id. NOTE: These QoS policies can not be applied to the console or vty connections.

2.23. Jumbo Frames The minimum jumbo frame size supported is 1552. The 2-port 10 Gigabit Module (3C17512) supports Jumbo Frame sizes of 1518, 1536, 1552, 9022, 9192 and 10240. Setting the jumbo frame size to a value other than these supported values will automatically set the value to the next higher jumbo frame size. For example, setting the jumbo frame to 9216 will set the jumbo frame size to 10240 for the port.

2.24. SFTP The Switch 8800 V5.01.20/V5.01.21 supports one SFTP connection only.



When a file is copied from SW8800 flash to a local drive, the file date is not changed so the local and flash files have the same date. When a file is copied from local to flash, the file date follows the SW8800 clock time (via CLI command "dir") and it shows different time - three hours behind the time from WinSCP. For example, the SW8800 clock time is 14:55:00 UTC Fri 2006/06/02. When a file is copied from local to the SW8800 flash via WinSCP (running on Windows XP with time zone of Eastern time), the file date is 14:55:00 on the SW8800, but on WinSCP, the original file date is 6/2/2006 11:55:00 AM. Can't rename file name on Flash if the file size is very large. When a file over 1.5M in size is renamed on the SW8800 flash, it returns "Error renaming file 'xxx' to 'yyy'. Error decoding SFTP packet (9,4,9)" Can't edit a file on Flash, if the file size is very large. It causes the SSH connection to drop and requests that the user re-login. If the passphase to login again is entered, SW8800 "display users" shows two SFTP connections, although there is only one SFTP connection at this moment.

2.25. Super User Password The ls.pwd file is where the super user password is stored. This file is created automatically when the super user password is configured. Do not delete this file, otherwise the super user password will be lost. Please remember to backup this file in addition to the configuration file. Once this file is deleted, there is no way to retrieve the existing super user password. If this should happen, you must create a new password for the super user.

2.26. 802.1x When Microsoft Windows 2000 IAS server is enabled with DNS server/client services and the Preferred DNS server address is configured on the NIC card, 802.1x Authentication may fail the first authentication from 802.1x client side and request authentication twice. 3Com suggest that you remove the DNS server address on the NIC card or use the loopback IP address (127.0.0.1) When a large number of users conduct 802.1X authentication, it is suggested that the handshake time be prolonged to 180 seconds. Otherwise, as the number of users passing the authentication grows, some of the online users will be forced to go offline due to handshake failure. When the number of users exceeds 1,000, only a few users remain online. PAP does not work with 802.1x. Vlan auto-assignment using mac authentication does not work..

2.27. Hardware On the 3C17532 module, you cannot perform egress port mirroring as destination port on an Access or Hybrid untagged port; Otherwise, the mirrored packets may be incorrectly tagged. As a result, some network adapters cannot identify the packets. The heat dissipation is not satisfactory if a 3C17526 module is inserted in slot 0 of a 14-Slot chassis. If it is necessary to use a 3C17526 module, please do not inserted in the slot 0 of the 14-Slot chassis. Otherwise, the four 10GE port cooling fans will be overheated, with the temperature exceeding the normal work range (0~70°C).



When 3C17536 and 3C17538 modules are installed in the Switch 8800 chassis, they are in a power down state by default. The user must manually power them up before they can be used.

2.28. ECMP Load sharing can be implemented on only 2~6 equivalent routes. It is suggested that no more than 6 equivalent routes be used, or load sharing will be degraded.

Load sharing can be implemented through aggregations of only 2~4 links. No more than 4 links should be used for aggregations, or load sharing through the link aggregation will not achieve a satisfactory result

2.29. SSH The password-control login-attempt does not determine how many times one SSH user can retry his password before he is put into the blacklist. Instead, it is the ssh server authentication-retries command that will control an SSH user's retry attempts.

If the user wants to have both Telnet and SSH service types available, they must be added at the same time. If they are added one at a time, the second service type entered will replace the first service type, rather than being added to it.

When using password control, the telnet session is terminated after 3 attempts, no matter what the password-control login-attempts is set to. This is a change in operation from previous releases where the telnet session was not terminated until the password control login limit was reached. As in previous releases, however, the user is not blacklisted until the password control login attempts limit is reached. For example, if password-control login-attempt is set to 10, the user will be able to make 3 attempts before the telnet session is terminated. The user can re-establish telnet and make another 3 attempts. This can be done until 10 attempts have been reached, at which point, the SW8800 will lock the user out for the specified time.

2.30. Web Authentication / Portal Web Authentication / Portal functionality is displayed in the command line interface, however, the feature is not supported.

2.31. RIPng When using RIPng route summarization, the switch will stop sending updates of the summarized routes out of some of the other interfaces.

2.32. SFTP Configuration Backup & Restore It is not possible to backup or restore the configuration if the configuration file is on compact flash when using SFTP.



Workaround: please configure the default directory for the user before initiating the SFTP transfer, e.g. local-user 3com work-directory cf:/ service-type ssh

2.33. MAC Authentication When a MAC address is sent to a RADIUS server for authentication, the Switch 8800 will send the MAC addresses without dashes (e.g. 00301bae794a rather than 00-30-1b-ae-79-4a).

When authenticating MAC Addresses, the Switch 8800 sends user names and passwords to the RADIUS server in lower case, regardless of how the user enters it (upper or lower case) on the Switch.

2.34. Gratuitous ARP – Change in default operation Beginning with the 5.01.20 release, by default, the SW8800 will not cache an ARP entry when it is sent a gratuitous ARP. You can change this by using the following command: [SW8800] gratuitous-arp-learning enable This change in default operation improves security, but may cause issues in certain circumstances. For example, a stacked device may change its MAC address if there is a change in the mastership of the stack. Usually gratuitous ARP is used to update connecting devices.

2.35. Tunnels IPv6 packets may use the IPv4 interface MAC address. If a “display interface vlan X” command is issued, the user will see a hardware (MAC) address for IP packet frame types and a hardware address for IPv6 packet frame types. Generally, when responding to an IPv6 ping, the SW8800 will respond with the IPv6 MAC address, however, when forwarding or tunneling an IPv6 packet the user will generally see the IP MAC address. Be aware of this when setting up ACLs or monitoring traffic. Tunnels (IPv6/IPv4, GRE) do not support multicast. This is included in the documentation – but is also included here for clarity. Some tunnels may allow PIM to be configured on the tunnel interface, however, multicast traffic will not cross the tunnel. 3Com uses a different IPv6 tunnel MTU than Cisco. MTU is 1500 for 3Com and 1480 for Cisco. If OSPF is being run between the tunnel interfaces, users should set the 3Com IPv6 MTU to 1480 in interface tunnel view. See the following example for tunnel 2/0/1: [SW8800] interface tunnel2/0/1<cr> [SW8800-Tunnel2/0/1] ipv6 mtu 1480 <cr> [SW8800-Tunnel2/0/1] quit <cr>



2.36. Selective QinQ Rather than using the port priority to fill in the priority in the outer tag, selective QinQ maps the inner priority to the outer tag. Users can workaround this by using “remark behavior” to control the outer priority tag as follows: [SW8800]traffic behavior 1 [SW8800-behavior-1]remark dot1p 7

2.37. Host Name Length For IPv4, the maximum host name (for ping, telnet, ftp, tftp, traceroute, etc.) is 20 characters. If using hostnames longer than 20 characters, please use the IP address directly for ping, etc. NOTE: The default domain name is in addition to the 20 character limit. For example, if the host name is 19 characters and the default domain name is another 6 characters - that will work, as long as the user pings hostname rather than ping hostname.defaultdomainname.

2.38. 3C17532 and 3C17532A Limitations 3C17532 and 3C17532A modules are designed to be used as access modules. They are supposed to be connected to PCs, rather than connected into the core of the network. In addition to the standard list of limitations for the 3C17532 and 3C17532A access modules, the modules have the following additional limitations

1. Modules have 4 queues rather than 8 queues. 2. Modules may not prioritize packets as expected depending on which ports are used for

incoming streams. 3. Port mirroring may experience issues:

a. On tunnel interface, may only see inbound traffic, even if both directions are selected.

b. May not be able to setup remote mirroring with the 3C17532 as the remote source. 4. With QinQ, 2 tags may be added to an untagged packet. In most instances, users should

avoid using untagged vlans connected to the QinQ enabled port – this will eliminate this problem.

2.39. IGMP When running IGMPv3 please be sure that all multicast clients are also IGMPv3 capable. If not, 3Com suggests running IGMP version 2. Within a single VLAN running IGMP version 3, multicast will always forward to a client regardless of the message type sent by the end station.

2.40. UDP Helper

UDP helper does not forward a packet with a time to live (TTL) of 1. It decrements the TTL during the forwarding process. This may cause issues with protocols like UNIX NIS, which are generated with a TTL of 1. It should NOT be a problem with protocols like NetBios that are generated with a higher TTL.



2.41. Documentation Addendum The following information is missing from the Switch 8800 documentation: Setting up Selective QinQ The SW8800 uses QoS Policies to setup selective QinQ. The following example shows how to map an incoming packet with a customer tag of vlan 3 and 4 with an outer (service vlan) tag of 5. Policy is applied to port gigabit-ethernet2/1/1 # Create the traffic classifier # Yes – you do want to use if-match service-vlan-id in this case. At the end of the process vlans 3 and 4 will be the customer vlan ids – but as incoming packets, they are NOT encapsulated yet. Therefore they are the outer tags.

Chapter 3 Upgrading Software

3.1.1. IMPORTANT NOTES:

Always save the configuration file before upgrading software images.

At the present time the flash on the 3C17508 fabric (360Gig) is not large enough to store the 5.01.21 image. The .app file is approximately is 30165 KB. The size of the 3C17508 fabric (360Gig) flash is 15621 KB. Use the compact flash to store and boot the image and any backup images. The compact flash is sufficient to store multiple images. The 3C17539 fabric (720Gig) on-board flash is large enough to store a primary and backup image. The size of the 3C17539 fabric (720Gig) flash is 64389 KB. If desired, the primary image could be stored on flash, and the backup image could be stored on compact flash. Be aware that the configuration file (the .cfg file) can often be larger than 5KB when deciding on how to layout the file system.

Upgrade from V3 to V5 is not supported by the Agent Update functionality in 3Com Network Director and Enterprise Management Suite. However, upgrade within V5 (i.e., from v5.01.20 to v5.01.21) is supported.



Be aware that the 5.01.21 release contains not only operational code for the fabrics (88h05_01_21s168rec01.app), but also boot code images for the fabric and the I/O modules. The fabric bootROM code is named fab05_02_06d.app (current version is 206) and the I/O module bootROM code is named iom05_01_08.app (current version is 108). Use the _display ver command to examine the current BootROM Version.

The 8800 Switch Fabric MUST be running bootROM V206 or greater before attempting to boot the 5.01.21 operational code. If this is not done, the Fabric will not boot up properly.

When upgrading to the v5.01.21 image, make sure that the fabric operational code, fabric bootROM code and I/O module bootROM code are upgraded BEFORE the Switch 8800 is rebooted. If this is not done, the Switch 8800 will not boot up properly.

If the I/O modules are currently running bootROM code version V103 or earlier, you cannot upgrade directly to V108 bootROM code. You must upgrade to V107 bootROM code first and then after the Switch 8800 is rebooted the I/O modules can be upgraded to V108 (iom03_01_08.app). If you try to upgrade from bootROM code V103 or earlier directly to V108, the system will prompt that the upgrade file is not compatible and the upgrade will fail. V107 bootRom code is included with the 5.01.21 release bundle in the event that you need to upgrade to this version of bootRom code first. The V107 bootROM code is named 8800boot-module1107.app.

The bootROM file must be on each fabric that is being updated. You can not update bootROM on the slot 1 fabric if the bootROM file is only on slot 0. Copy the bootROM file to the file system of slot 1. More recent application files support the bootROM file being stored on compact flash or flash, but earlier versions may require that the bootROM file be on flash.

To upgrade the software application image of a 7, 10 or 14 slot Switch 8800, use the applicable procedures in sections below for upgrading through FTP, Boot Menu, Xmodem, or TFTP. FTP and tftp are much quicker than using the boot menu procedure or Xmodem. Xmodem has a much slower download speed because the serial port is used. In addition, updating a unit with dual fabrics is more difficult when using the boot menu/Xmodem.

Unless indicated otherwise, the examples use the slot numbering for a 7-slot chassis. Slots 0 and 1 on a 7-slot contain the master and slave fabrics respectively. These slots correspond to slots 4 and 5 on a 10-slot chassis and to slots 6 and 7 on a 14-slot chassis. The examples also assume that the master fabric is in the lower numbered slot – which is usually but not always the case. The master fabric may also be referred to as the primary fabric. The slave fabric may also be referred to as the secondary fabric.

When setting the boot-loader – always use the full path name flash:/, slot1#flash, cf:/, cf0:/, slot1#cf:/, slot1#cf0: and confirm that the file has been set correctly using the display boot command.

If a compact flash is used – ensure that it is recognized when the dir cf:/ or dir cf0:/ or the dir slot1#cf:/ or the dir slot1#cf0:/commands are issued. If not recognized – it may not be formatted correctly for use with the 8800. If necessary, use the format cf: or format cf0: command with caution. Format will erase the contents of the compact flash.



Before you upgrade the software image, there are several things to remember: Confirm if an operational code has been loaded before initiating software upgrade.

Check the current version of the operational code and Boot ROM version of the modules before upgrading. To inquire about the current versions number:

<SW8800>_display version

3Com Corporation

3COM OS SW8800 V5.01.21s168rec

Copyright(c) 2004-2007 3Com Corporation and its licensors. All rights reserved.

Switch 8800 uptime is 0 week, 5 days, 4 hours, 45 minutes

Back up the current image, BootROM program files (.app files) and configuration files to a PC or an FTP or tftp server, for possible rollback in case of failed upgrade. An example using FTP to backup these files is located here Backing up the configuration file and the operational OS agent.

After you install the redundant fabric module, you must wait for several minutes [at least 6 minutes] until a CLI message indicates that the slave is synchronized to the master, then save the configuration. Use the command display switchover state to verify the synchronization state. Fabrics are synchronized when the message real time and routine backup is displayed. For example:

Fabrics are NOT synchronized: <SW8800>dis switchover state HA FSM State(master): Waiting batch backup request from slave.

Fabrics are synchronized: <SW8800>dis sw st

HA FSM State(master): Realtime and routine backup to slave.

When upgrading through the boot menu, use the management port on the master fabric to download an application code. For tftp/ftp, you can use the management port (the Ethernet port on the fabric) or a VLAN interface (in-band Ethernet port on an I/O module, not a Network Application Module).

You must set the boot-loader file to the new boot-loader name file after you download it. This has to be done on each fabric. For example, in a 14 slot Switch 8800 with dual fabrics:

<SW8800> boot-loader file cf:/88h05_01_21s168rec01.app slot 6 main

<SW8800> boot-loader file slot7#cf:/88h05_01_21s168rec01.app slot 7 main

Use the display boot-loader command to verify:

<SW8800> display boot-loader

The primary app to boot of board 6 at the next time is: cf:/88h05_01_21s168rec01.app

The primary app to boot of board 7 at the next time is: cf:/88h05_01_21s168rec01.app



<SW8800>

Note: Above application name may vary.

After you upgrade both fabrics and upgrade the BootROM code (Upgrading BootROM Code Using the Command Line Interface ) and save the configuration, then you must reboot the switch so the new software code can be loaded.

You can check free space on the Switch 8800 with the dir command, in user view. Example: For a 7 slot chassis with dual fabrics – master fabric in slot 0, slave fabric in slot 1 - the commands dir, dir cf:/, dir slot1#flash:/ and dir slot1:cf:/ are required to check free space on the master fabric, master compact flash, slave fabric and slave compact flash, respectively. Use cf0:/ rather than cf:/ if already at v5.01.21.

You may need to delete files and clear the recycle bin (using the delete file and reset recycle-bin commands) to make room for a new application image file. These commands (delete <slot1#flash:/file> or delete <slot1#cf:/file> and reset recycle slot1#flash:/ or reset recycle slot1#cf:/) need to be executed for both the master and the slave fabric modules. Reset recycle bin can take minutes depending on how many bytes are in the recycle bin. Use cf0:/ rather than cf:/ if already at v5.01.21.

Another way to delete a file permanently is by issuing the delete /unreserved filename command. This can take minutes depending on the size of the file.

It may be useful in some cases to download directly to compact flash (cf). The procedures below do not require this if the fabric is a 3C17539 fabric (720Gig). If the fabric is a 3C17508 fabric (360Gig) this will have to be done. To copy directly to compact flash, use the destination option. For example: instead of using: tftp 10.10.110.1 get 88h05_01_21s168rec01.app use: tftp 10.10.110.1 get 88h05_01_21s168rec013.app cf:/ 88h05_01_21s168rec01.app. Use cf0:/ rather than cf:/ if already at v5.01.21.


Upgrade to the latest boot code on the fabric(s) or the fabric(s) will not boot up properly. Upgrade should occur at the point indicated in the following procedures.

3.2. General Upgrade Procedure To upgrade the Switch 8800:

1. Copy the existing application code from the flash to the compact flash to ensure that a valid image exists on the 8800. [This step is optional. It is recommended that you always maintain a valid APP file on flash/compact flash. However, it is not required. Just do NOT reboot without a valid APP file and make sure the boot-loader is configured to boot from that valid APP file.]

In the following example, dual fabrics are installed in a 7-slot chassis. Use the following commands:

<SW8800> copy 88h05_01_21rec01.app cf:/ 88h05_01_21rec01.app

<SW8800> copy slot1#flash:/ 88h05_01_21rec01.app slot1#cf:/ 88h05_01_21rec01.app




2. If NOT already running the latest boot code - upgrade the BootROM - Upgrading BootROM Code Using the Command Line Interface for more details. The current release of BootROM for the fabrics is 206, for the I/O modules it is 108.

3. Ensure sufficient space on the master and slave fabric flash(es) or compact flash (cf:/) to hold the new application code (.app files). See the dir commands described above. Delete files as necessary; see the delete and reset recycle commands described above. The code size for Advanced Code 88h05_01_21s168rec01.app is 30,888,988 bytes. The bootROM code for the fabric(s) (fab05_02_06d.app size is 326896) and I/O modules (iom05_01_08d.app size is 207696) will be placed on flash:/ on the fabric(s).

4. If the fabric is a 3C17539 720 Gbps fabric, download the new software OS agent code to the master fabric’s flash:/ or cf:/ (compact flash) in Slot0 in a 7-slot chassis, Slot4 in a 10-slot chassis, and Slot6 in a 14-slot chassis using one of the procedures outlined in Upgrading Application Software using FTP, Upgrading Application Software Using the BOOT Menu, Upgrading Application Software Using Xmodem or Upgrading Application Software Using TFTP. Do not issue the reboot command until the bootROM has been updated.

If the fabric is a 3C17508 360Gbps fabric, download the new code to the master fabrics compact flash (cf:/) in Slot0 in a 7-slot chassis, Slot4 in a 10-slot chassis, and Slot6 in a 14-slot chassis using one of the procedures outlined in Section Upgrading Application Software using FTP, Upgrading Application Software Using the BOOT Menu, Upgrading Application Software Using Xmodem or Upgrading Application Software Using TFTP. Do not issue the reboot command until the bootROM has been updated.

5. If the fabric is a 3C17539 720Gbps fabric, copy the new code from the master fabric flash:/ or cf:/ and to the backup fabric flash:/ or cf:/:

Slot0 to Slot1 in a 7-slot chassis


Slot 6 to Slot7 in 14-slot chassis

Use the following command to copy to flash:/: <SW8800> copy flash:/88h05_01_21s168rec01.app slot1#flash:/88h05_01_210s168rec01.app

Use the following command to copy to cf:/:

<SW8800> copy cf:/88h05_01_21s168rec01.app slot1#cf:/88h05_01_21s168rec01.app It can take several minutes to copy the code from the master to the slave fabric. The CLI will not respond during this operation.

If the fabric is a 3C17508 360 Gbps fabric copy the new code from the primary fabric cf:/ to the backup fabric cf:/ :



Slot 6 to Slot7 in 14-slot chassis

Use the following command: <SW8800> copy cf:/88h05_01_21s168rec01.app slot1#cf:/88h05_01_21s168rec01.app It can take several minutes to copy the code from the master to the slave. The CLI will not respond during this operation.

6. Use the following commands to configure the boot loader with primary and backup app files.



Use these commands if running software OS V3.x.x: Below are the primary files the switch fabrics will load upon boot. <SW8800> boot boot-loader pri flash:/88h05_01_21s168rec01.app slot 0 <SW8800> boot boot-loader pri slot1#flash:/88h05_01_21s168rec01.app slot 1 Optional: Below are the backup files the switch fabrics will load if there is a problem with the primary files. <SW8800> boot-loader backup cf:/88h03_01_31s256rec02.app slot 0 <SW8800> boot-loader backup slot1#cf:/88h03_01_31s256rec02.app slot 1

Note: Above application name may vary. Use these commands if running software OS V5.x.x: Below are the primary files the switch fabrics will load upon boot. <SW8800> boot-loader file flash:/88h05_01_21s168rec01.app slot 0 main <SW8800> boot-loader file slot1#flash:/88h05_01_21s168rec01.app slot 1 main Optional: Below are the backup files the switch fabrics will load if there is a problem with the primary files. <SW8800> boot-loader file cf:/88h05_01_20s168rec03.app slot 0 backup <SW8800> boot-loader file slot1#cf:/88h05_01_20s168rec03.app slot 1 backup

Notes:

1. Above application name may vary.

2. If already at v5.01.21 – use cf0:/ rather than cf:/

7. Use the display boot command to ensure that the boot loader has been set correctly.

8. Save the configuration. Make a backup copy of the configuration if not already done. Display start will display the current configuration file. You can also make a copy of the current configuration file with a different name, it can be saved to flash: and/or cf: (compact flash) on the master and backup fabrics. See the example below. It can also be backed up to an FTP or tftp server.

Example, the startup file is named sw8800dc1.cfg. Your configuration file will have a different name.

<SW8800>save

The configuration will be written to flash:/sw8800dc1.cfg

Are you sure?[Y/N]y

Now saving current configuration to the device.

Saving configuration flash:/sw8800dc1.cfg. Please wait...

9. Issue the reboot command and enter Y at the reboot prompt so the system reboots.

10. User can verify which code is running by using the display version or the _display version command.

11. After the reboot, the configuration file will need to be reconfigured using the start saved-configuration (configuration pathname) command. This is only necessary once. You will need access to the console port. You will NOT be able to telnet into the Switch 8800 at this time. Then reboot the switch again. Answer Y to the question “Current configuration will be lost in next startup if you continue. Continue?”.

IF YOU ARE UPGRADING FROM V3.01.02 1. V3.01.02 does NOT support a backup image – so the boot-loader commands are

somewhat different.

a. Perform steps 1 thru 5 above – except that you are upgrading from 3.01.02 rather than 3.01.21.

b. After downloading the new code, change the boot-loader on the master to boot the new code using the following command and specify the appropriate slot for your chassis. <SW8800> boot boot-loader flash:/88h05_01_21s168rec01.app slot 0

c. After downloading the new code, change the boot-loader on the slave to boot the new code using the following command and specify the appropriate slot for your chassis. <SW8800> boot boot-loader slot1#flash:/88h05_01_21s168rec01.app slot1

d. Upgrade the bootROM code using section 4.6

e. You can use the display boot-loader command to verify that the new code will run the next time the chassis is booted.

f. Save the configuration, then issue the reboot command and enter Y at the reboot prompt so the system reboots

g. User can verify which code is running by using the display version or the _display version command

2. After upgrading to the new code, a backup image can be set.

a. Set a primary and backup file as shown in Step 6 above.



b. Use the display boot command to ensure that the boot loader has been set correctly

c. Save the configuration, then issue the reboot command and enter Y at the reboot prompt so the system reboots

d. User can verify which code is running by using the display version or the _display version command.

NOTE: In the following examples, the IP address of the local computer which is acting as the FTP or TFTP server is 10.10.110.1 and the image is 88h05_01_21s168rec01.app. Actual IP addresses and filenames will depend on your system and software versions.

User input is bold faced.

These examples assume that the Switch 8800 is set up with an IP address on the Ethernet port on the fabric. To set up the Ethernet port on the fabric with an IP address, use the following commands in super-user mode:

[SW8800]interface M-Ethernet 6/0/0

[SW8800-M-Ethernet 6/0/0] ip address 10.10.110.2 255.255.255.0



3.3. Upgrading Application Software using FTP NOTE: There are FTP/TFTP servers on the 3Com.com website. Search for “tftp server”. They are located in “3Com Software Library – Utilities for 32 bit Windows”

Before you upgrade:

• Make sure you have access to the console port (serial port- 9600 Baud, 8, 1 and parity is none) on the fabric.

• Verify that there is a connection between the FTP server and the Switch 8800 (use the ping command).

• Verify that the FTP server is setup according to the manufacturer’s instructions and that it is enabled and pointing to the correct upload/download directory. This is the directory that contains the files that will be used for the update. The needed files are 88h05_01_21s168rec01.app, iom05_01_08d.app and fab05_02_06d.app.

• When using the Switch 8800 as an FTP client, if this is message is returned:

202 Command PASV not implemented

Enter undo pas at the [ftp] prompt.

There are two ways of downloading program files: FTP to a local PC from a switch and FTP to a switch from a local PC. In the first mode, a PC with FTP server application serves as a FTP server.

There is a complete update procedure example using FTP in section Software Update Example.

Use the following procedure to upgrade software using the first method:

1. Login to the switch with super-user privileges, usually user admin.

2. Verify that there are enough free space on flash: and/or compact flash on the fabric(s) to copy the files needed. The software OS agent file 88h05_01_21s168rec01.app size is 30888988 records. The bootROM code for the fabric(s) (fab05_02_06d.app size is 326896) and I/O modules (iom05_01_08d.app size is 207696) will be placed on flash: on the fabric(s). See sections IMPORTANT NOTES: and General Upgrade Procedure for more information on the file system commands. For an example, see section Ensure sufficient space on the master and slave fabric flash(es) and/or compact flash (cf:/) to hold the new application code (.app files).

3. Upgrade the BootROM code by using the upgrade procedures in section Upgrading BootROM Code Using the Command Line Interface

4. Identify the currently used configuration file.

5. From the Switch 8800 command line, FTP the file from the FTP server to the system.

6. Copy the application file from the primary fabric to the backup fabric.

7. Set the boot parameters to specify the file to boot the system from.

8. Reboot the system. Make sure you can access the console port before you reboot.

9. After the reboot, the configuration file will need to be reconfigured using the start saved-configuration (configuration pathname) command. This is only necessary once. You will need access to the console port. You will NOT be able to telnet into the Switch 8800 at this time. Then reboot the switch again. Answer Y to the question “Current configuration will be lost in next startup if you continue. Continue?”.

The following example illustrates this procedure:



NOTES:

1. The general upgrade procedure (General Upgrade Procedure and IMPORTANT NOTES:) contains more details related to copying files, etc.

2. The following example illustrates this procedure. This procedure was done using the console port on the primary fabric.

For more detailed descriptions of the set up and procedures for upgrading software, see the remaining sections in this chapter.

In second method, a switch serves as a FTP server. Users log in the switch from a local PC by FTP.

Configure switch to be an FTP Server. Create a user account (8800) to use the switch as an FTP server. The local-users working directory on the switch is compact flash (cf:/) or flash:/. The working directory should be where the software OS agent file 88h05_01_21s168rec01.app will reside. Enter the system view (sys), if not already in the system view.

[SW8800]ftp server enable

% Start FTP server

[SW8800]local-user 8800

3.4. Upgrading Application Software Using the BOOT Menu This section illustrates an upgrade of the Switch 8800 through the BOOT menu using TFTP. You can also use FTP by entering information for FTP in Step 6.

To perform this procedure, you must have a network connection to the Ethernet port on the Switch 8800 master fabric module. This procedure is done from the console port on the master fabric.

New application code will NOT run with older bootROM code. Please update bootROM code first. See section Upgrading BootROM Code Using the Command Line Interface. Make sure there are enough free records to fit the file 88h05_01_21s168rec01.app, size is 30888988 Bytes. If the fabric is a 3C17508 fabric (360Gig), the file has to be loaded on CF:/ (or CF0:/). For more information on file system commands, see sections IMPORTANT NOTES: and General Upgrade Procedure.

After powering on the Switch 8800 or after a reboot of the Switch 8800, the BootROM program runs automatically. In the examples below the new software OS agent code 88h05_01_21s168rec01.app is loaded on CF:/. (CF0:/ if already running 5.01.21)

The terminal displays the following information: NOTE: If at BootROM code 206, the following banner will be displayed. If not at bootROM code 206 – STOP – do NOT proceed. Go to Upgrading BootROM Code Using the Command Line Interface . The new application code will not run with older versions of boot code.

Press ENTER to get started.

Log in to the system with super-user privileges, usually user admin. If this message is displayed: “System is in slave status; can't respond to your command.” Mastership on the fabrics changed over to the slave. Move the serial and Ethernet cables to the other fabric.

Note: You must insure the upgrade of the operational OS agent code is compatible with the existing Boot ROM program of the I/O module. Otherwise, you have to upgrade them during fabric Application program upgrade.

3.5. Upgrading Application Software Using Xmodem The Xmodem protocol transmits files through a serial port and supports both 128-byte and 1K-byte packets. The Switch 8800 only supports 128-byte transfers. Xmodem also supports two types of check; normal checksum and CRC. When there is a packet error, retransmission is supported, normally 10 times.

The Xmodem protocol completes transmission by receiving and sending programs. The receiving program first sends the negotiating characters to negotiate the check means. After passing the negotiation, the sending program begins to send the packet. The receiving program checks the packet according to the negotiated means after receiving a complete packet. The acknowledgement characters are sent after passing the check and then the sending program continues to send the next packet. If the check fails, negative characters are sent and the sending program sends the packet again.

NOTE: The default console port connection is 9600 Baud, 8 Data Bits, Parity none, 1 Stop bit and None for flow control.

To perform this procedure, you must have a serial connection to the console port on the Switch 8800 master fabric module. Windows HyperTerminal was used in the examples. It can normally be found at Start>All Programs>Accessories>Communications>HyperTerminal. The file 88h05_01_21s168rec01.app is needed for this procedure, it is also on this same PC.

After powering on the Switch 8800, the BootROM program runs automatically. The terminal displays the following information: NOTE: If at BootROM code 206, the following banner will be displayed. If not at bootROM code 206 – STOP – do NOT proceed. Go to section Upgrading BootROM Code Using the Command Line Interface. The new application code will not run with older versions of boot code.

3.6. Upgrading Application Software Using TFTP TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that is used without complex interaction between clients and servers.

The client initiates a TFTP transmission. To download files, the client sends a read request packet to the TFTP server, receives the packet from the server, and sends the acknowledgement to the server. To upload files, the client sends a write request packet to the TFTP server, sends the data packet to the server, and receives the acknowledgement from the server.

Switch 8800 provides the functions of the TFTP client.

FYI: There are FTP/TFTP servers on the 3Com.com website. Search for “tftp server”. The servers are located in “3Com Software Library-Utilities for 32 bit Windows”.

Before you upgrade:

Make sure you have access to the console port (serial port- 9600 Baud, 8,1 and none) on the master fabric.

Verify that there is a connection between the TFTP server and the Switch 8800 (use the ping command).

Verify that the TFTP server is set up according to the manufacturer’s instructions and that it is enabled and pointing to the correct directory. This is the directory that contains the files that will be used for the update. The needed files are 88h05_01_20s168rec03.app, iom05_01_08d.app and fab05_02_06d.app.

To upgrade using TFTP:

1. Verify that you are logged in with super-user privileges.

2. Verify that there are enough free records on flash: and/or compact flash on the fabric(s) to copy the files needed. The software OS agent file 88h05_01_21s168rec01.app size is 30888988 records. The bootROM code for the fabric(s) (fab05_02_06d.app size is 326896) and I/O modules (iom05_01_08d.app size is 207696) will be placed on flash:/ on the fabric(s). For more information on the file system, see IMPORTANT NOTES: and General Upgrade Procedure

3. Upgrade the BootROM - see section Upgrading BootROM Code Using the Command Line Interface.

4. Identify the currently used configuration file.

5. From the Switch 8800 command line (in user view), TFTP the image file from the TFTP server to the Switch 8800 using the following command: tftp <TFTP Server IP Address> get <Source File/image>< Dest File-Optional>

6. Set the boot parameters to specify the file to boot the system from, using the following command: boot boot-loader <pri/backup> filename slot (fabric slot number) or if on a Com5 code version – boot-loader file filename slot (fabric slot number) <main/backup>

7. Copy the software OS agent application code from the primary fabric to the backup fabric.

8. Reboot the system. Make sure you can access the console port on the master fabric before you reboot.

9. After the reboot, if upgrading from a V3 code version to a V5 code version, the configuration file will need to be reconfigured using the start saved-configuration (configuration file pathname) command. This is only necessary once. It is also not necessary if upgrading between V5 code version. You will need access to the console



port. You will NOT be able to telnet into the Switch 8800 at this time. Then reboot the switch again. Answer Y to the question “Current configuration will be lost in next startup if you continue. Continue?”.

The following example illustrates this procedure using the software OS agent code filename: 88h05_01_21s168rec01.app. This procedure was done from the console port on the master fabric. The currently running software OS agent code and configuration files have been backed up.

NOTE: The general upgrade procedure (IMPORTANT NOTES: and General Upgrade Procedure sections) contains more details on copying files and making sure there are enough free records on flash: and/or compact flash (cf:), etc. See section Ensure sufficient space on the master and slave fabric flash(es) or compact flash (cf:/) to hold the new application code (.app files). for an example.

3.7. Upgrading BootROM Code Using the Command Line Interface

3Com recommends that you upgrade the BootROM code in parallel with the operational code. The new application code will NOT run with older versions of boot code.

The latest BootROM code in the 5.01.21 release is version 206 (fab05_02_06d.app) for the fabric and version 108 (iom05_01_08.app) for the I/O modules.

If the I/O modules are currently running bootROM code version V103 or earlier, you cannot upgrade directly to V108 bootROM code. You must upgrade to V107 bootROM code first and then after the Switch 8800 is rebooted the I/O modules can be upgraded to V108 (iom03_01_08.app). If you try to upgrade from bootROM code V103 or earlier directly to V108, the system will prompt that the upgrade file is not compatible and the upgrade will fail. V107 bootRom code is included with the 5.01.21 release bundle in the event that you need to upgrade to this version of bootRom code first. The V107 bootROM code is named 8800boot-module1107.app.

Except as noted below – until the full application upgrade has been completed as described in the sections above - it is NOT required to reboot the device. You can set the new boot code and the new OS application agent code simultaneously –then reboot and the device will come up with the new application/boot code combination.

Use the following procedure to upgrade boot code on each switch fabric and I/O module. The slot number for the switch fabric depends on the chassis. Please download fabric bootROM file fab05_02_06d.app to both master and slave switch fabrics.

1. Login to the switch with super-user privileges, usually user admin.

2. If not already backed up, save the configuration file and currently running software OS agent code by uploading it to a temporary server. Use the command display start to display the currently used configuration file. Use the display boot to display the currently used primary software OS agent code. Make a note of these files.

Use one of the download procedures in these Release Notes.

3. Check the current bootROM versions to see which fabric(s) and I/O modules are going to

need to be updated, use the _display version command. 4. Check to see if there are enough free records in the flash:/ file system on the fabrics to

download the bootROM app files. The bootROM code for the fabrics (fab05_02_06d.app size is 326896) and I/O modules (iom05_01_08d.app size is 207696) will be placed on flash:/ on both fabrics. IMPORTANT NOTES:and General Upgrade Procedure provides more details on the commands needed to examine the file system and remove files. An example of examining the file system can be found at Ensure sufficient space on the master and slave fabric flash(es) or compact flash (cf:/) to hold the new application code (.app files).

Using one of the download procedures in these Release Notes:

5. Download the latest bootROM app files (fab05_02_06d.app and iom05_01_08d.app) to the master fabric.

6. Download the fab05_02_06d.app bootROM app file to the slave fabric or copy the file from the master fabric to the slave fabric.

7. Update the bootROM code using the following commands:



Example, if running rev 3.x.x: <SW8800>boot bootrom fab05_02_06d.app slot 6 If running rev 5.x.x:

<SW8800>bootrom update file flash:/fab05_02_06d.app slot 6

3.7.1. Example of Updating the bootROM code on the fabric(s) and I/O modules. Below is an example of the above procedure using an FTP server and a 10-slot Switch 8800 with dual fabrics installed in slots 4 and 5. The Switch 8800 has an IP address of 158.101.23.252/24. The FTP servers address is 158.101.23.100/24. The file system has already been checked for available free records. Login to the switch with super-user privileges, usually user admin. Check the current bootROM versions to see which modules are going to need to be updated, use the _dis ver command. In the example below both Fabrics in slot 4 and 5, are running BootROM Version 203- rev 206 is the current rev. The I/O modules in slot 0 and 2 need to be updated from BootROM Version 107 to Version 108.

Frame 0 IO Board 2 upgrade BOOTROM succeeded If you can not get the new bootROM code loaded on the fabrics, stop now,

t and call customer service support if you can not resolve the problem. Do noproceed any further until the new bootROM code has loaded successfully on the fabrics.



3.8. Upgrading the BootROM Code On the Fabric Using the Boot Menu This procedure would most likely be used only if the Command Line Interface, User and System Views can not be accessed. This could occur if the new software OS agent code (88h05_01_21s168rec01.app) was loaded and the switch was rebooted without updating the BootROM code on the fabric.

To perform this procedure, you must have a network connection to the Ethernet port on the Switch 8800 master fabric module. This procedure is done from the console port on the master fabric. A FTP or tftp server can be used. The file needed is fab05_02_06d.app, it is in the upload/download directory of the FTP/tftp server.

After powering on the Switch 8800 or after a reboot of the Switch 8800, the BootROM program runs automatically. NOTE: The new application code will not run with older versions of boot code.

2. The bootROM code file to be transferred has to be configured. In the example

below, the fabrics new bootROM code filename is fab05_02_06d.app, the IP address on the fabrics Ethernet port is 158.101.23.252, the IP address of the FTP server is 158.101.23.100. The FTP user id is Update, the password is password. FTP is going to be used to transfer the bootROM code file. The FTP server and the Switch 8800 are on the same IP network, so a gateway was not needed. Tftp could also be used, flags (f) would need to modified to 0x80. User input is bold.

3.9. Software Update Example In the example below a 10-slot Switch 8800, with dual fabrics is updated from rev 3.01.30 to rev 5.01.21. FTP is used to transfer the files. The files required for the update have been loaded on the FTP server. The files needed are 88h05_01_21s168rec01.app, fab05_02_06d.app and iom05_01_08d.app. If you have only 88h05_01_21s168rec01.zip, extract this file to get the afore mentioned files. The update was done from the console port on the master fabric. The default settings are 9600 Baud, 8 data bits, 1 stop bit and parity is None.

3.9.1. Identify the configuration file and the currently running operational OS agent file.

Check to see what files are being used for the bootup process and what is the configuration file. These files need to be backed up. The backup of the configuration file and the primary software OS file will be backed up using FTP later in the procedure. <SW8800>dis boot The primary app to boot of board 4 at the next time is: cf:/88h03_01_30s512rec06.app The backup app to boot of board 4 at the next time is: flash:/8500.app The app to boot of board 4 at this time is: cf:/88h03_01_30s512rec06.app The primary app to boot of board 5 at the next time is: cf:/88h03_01_30s512rec06.app The backup app to boot of board 5 at the next time is: cf:/88h03_01_30s512rec06.app <SW8800>dis start MainBoard: Startup saved-configuration file: flash:/sw8800dc1.cfg Next startup saved-configuration file: flash:/sw8800dc1.cfg SlaveBoard: Startup saved-configuration file: flash:/sw8800dc1.cfg Next startup saved-configuration file: flash:/sw8800dc1.cfg

3.9.2. Identify the bootROM versions and which modules will need the bootROM code to be updated.

To check the current bootROM versions use the _dis ver command. Both Fabrics in slot 4 and 5 are running BootROM Version 203- rev 206 is the current rev. The I/O modules in slot 0 and 2 need to be updated from BootROM Version 107 to Version 108. <SW8800> _dis ver 3Com Corporation 3Com OS Software Version COMWAREHZV300R001B09D021SP06 Switch 8800 Software Version V100R003B02D021SP06

e files can be transferred to the Switch 8800 in many ways, FTP, tftp, boot menu and xmodem

records, first try to reset recycle-bin to see if free records could be recovered easily. Next, files would have to be deleted (use the command delete /unreserved (filename)). I would start with oldest software OS file (.app) and old bootROM files after they where backed up to an FTP or tftp server.
