Software Version
• SW 6.9 has been successfully tested, pending
approval.
• Cannot use IP-10R3 software with IP-10R1, so
it is very important software upgrade task it is very important software upgrade task
must be carefully monitored
• If used, can cause memory corruption & need
to send for repair

Protection Port
Protection Port (only for standalone units) –
9
Protection Port (only for standalone units) –
Protect your Main unit with a STBY unit
Protection ports on both units deliver the proprietary protocol to
support automatic or manual switchover
The FE protection port is static (only used for protection, not traffic). Its switching is performed
electrically. If the unit is a stand-alone, an external connection is made through the front panel. If the
unit is connected to a backplane, the connection is through the backplane, while the front panel port
is unused.

Licensing: GeneralIn order to upgrade license, license-key must be entered to the system (requires cold-
reset)
When system is up, its license key is checked, allowing access to new capacities and/or
features
If license key is illegal (syntax error…illegal S/N…) specific alarm will be raised
When "License Violation" alarm is raised, Radio port capacity is automatically limited
to ~3Mbps, allowing only management channels to remote end
To clear the violation alarm, user must configure the system to comply with the loaded
license, and then, issue cold-reset (radio resumes full operational status if the
violation is no longer relevant)

Configuring external 1+1 from scratch
(1)
1. Set all IDUs to factory defaults
2. When IDUs complete the booting sequence, verify:
• All IDUs have the same HW version (same P/N)
• All IDUs have the same SW version
• All IDUs have the same license
28
• All IDUs have the same license
• Every IDU has unique IP address (within the same subnet)
• Active and STBY have the same SW mode (Pipe / Managed / Metro)
• All IDUs have the same Management mode (In band or OOB)
• In case of In-Band, all IDUs have the same In-Band VID
Note:
The IDU, which is connected to the ODU fed by the lower attenuation
channel of the RF coupler, is the IDU that should be selected as
"Active“.

VLAN TAG Attributes1. In L2 ETH switching, L2 traffic can be engineered using the VLAN TAG
attributes
2. L2 traffic is controlled by defining port membership: Access or Trunk
3. Together, port membership + L2 traffic engineering convert connectionless to
connection-oriented network
41
4. In such networks, services are better deployed and maintained
5. VLAN TAG attributes include:
• VLAN ID (12 bits)
• Priority Bits (3 bits)
6. Additional attributes may be used to engineer traffic:
• MAC DA
• Port number
![Page 42: 10 E Training Slide With R1 Knowledge_v3](https://reader036.vdocument.in/reader036/viewer/2022081401/563db7b2550346aa9a8d1ea3/html5/thumbnails/42.jpg)
Access Port• Access Port is a port which is aware of a single VLAN only
• Ingress traffic is expected to be Untagged, e.g. – no VLAN information
exists within the received Ethernet frame
• All frames that are received through this port are tagged with default
VLAN (VID + P bits)
42
VLAN (VID + P bits)
• All frames that exit through this port towards customer devices are
untagged (VLAN is removed)
• Users can configure the L2 switch to assign different tagging scenarios to
different ports
![Page 43: 10 E Training Slide With R1 Knowledge_v3](https://reader036.vdocument.in/reader036/viewer/2022081401/563db7b2550346aa9a8d1ea3/html5/thumbnails/43.jpg)

General guidelines• Access port can only receive untagged frames from customer device
• Access port can only transmit untagged frames towards customer device
• Access port supports single VLAN
• Access port can be connected to an Access port only
50
• Trunk port can only receive / transmit tagged frames
• Trunk port supports multiple VLANs
• Trunk port can be connected to a Trunk port only
• When configuring Access or Trunk port, membership needs to be defined next
(which VLANs are supported…)

Access + Trunk Port = Hybrid Port• Hybrid Port is a combination of access port which is aware of a single
VLAN only and trunk port that allows multiple VLAN
• Ingress untagged traffic is tagged with default VLAN
• Ingress tagged traffic passes through based on VLAN membership
configuration
51
• Egress tagged traffic with default VLAN is untagged
• Egress tagged traffic passes through based on VLAN membership
configuration
• Users can configure the L2 switch to assign different tagging scenarios to
different ports

Enhanced Traffic Manager
• The Enhanced Traffic Manager (ETM) improves the QoS capabilities by– Enhanced classification methods
– Improved scheduler
– Uses 8 queues (instead of 4)– Uses 8 queues (instead of 4)
– Supports shaping capabilities per queue
– Weighted Random Early Detect (WRED) support
– PTP Optimized Transport
– Enhanced performance monitoring and statistics
• The ETM applies only to Radio port egress traffic
• The ETM is licensed feature

• The output of the classification process
– Traffic Class of Service (CoS)
– Traffic marked color, either Green or Yellow
• CoS are mapped into queues
Classification Process Output
• CoS are mapped into queues
• The mapping is configurable

• Weighted Random Early Detect (WRED) algorithm is part of
the shaping process
• The goal of WRED algorithm is to prevent TCP global
synchronization problem
• TCP global synchronization is
Weighted Random Early Detect
• TCP global synchronization is
– when there is a congestion at the bottleneck, the radio port
– frames from all flows are dropped, do the nature of TCP
– Resulting in low throughput of the system

Weighted Random Early Detect
• The upper graph demonstrates
two flows of TCP traffic without
a WRED algorithm

• The lower graph demonstrates
two flows of TCP traffic with
WRED algorithm

Memory Queues
• The enhanced traffic manager
supports up to 8 memory queues
• The size of the memory allocated
for the queues is up to 4Mb
• The size of each queue is
configurable

configurable
• The default configuration is 0.5Mb
per queue

Egress Shaper
• Egress shaper is used to shape the traffic profile sent to the
radio
• There is an egress shaper for each priority queue
• Each queue can be configured with
– Committed Information Rate (CIR)
64
– Committed Information Rate (CIR)
– Commited Buffer Size (CBS)
• There is the possibility to enable/disable all queues at once
