TMPLS to MPLS-TP Upgrade Guide 1 Before You Start



1

1 Before You Start1.1 Upgrade Objective

This document guides you to upgrade the feature TMPLS OAM of the OptiX OSN3500/7500/7500 II to MPLS-TP OAM. After the upgrade, the OptiX OSN 3500/7500/7500 IIcan perform OAM operations with the peers that support MPLS-TP OAM.

1.2 Preparing for the Upgrade

The table below lists the preparations you need to complete before an upgrade.

Table 1-1Preparations for an upgrade

Item Description

Versions of the U2000 and NEsoftware

Upgrade the U2000 and NE software to the versionsthat support MPLS-TP.

Upgrade the NE software to V200R013C10SPC100.

Upgrade the U2000 to V200R001C00.

Hardware Ensure that the boards on the equipment meet thefollowing requirements:

The cross-connect board on the OptiX OSN 3500is SSN3PSXCSA.

The cross-connect board on the OptiX OSN 7500is SST2PSXCSA.

Ensure that the subrack type of the OptiX OSN3500/7500 meets the requirements described insection2.2 "Running Inspection Scripts."

Personnel Ensure that the upgrade personnel have the basic

network skills, master the common operations on theU2000, know basics about the transport equipment,and understand the concepts of MPLS-TP.

Item Description

Feature Before switching Y.1711 to Y.1731, ensure thefollowing conditions are met.

The OptiX OSN 3500 does not support two-slotboards.

Slots 26 to 31 on the OptiX OSN 7500 do notsupport packet boards.

The services that run the IGMP protocol do notsupport complex traffic c lassification.

The PWs configured with the interworkingfunction (IWF) do not support MPLS-TP OAM.

Switching to the dual-stack mode is notsupported if the number of enabled TMPLSOAM features exceeds 1024.

1.3 Method Introduction

An upgrade from TMPLS OAM to MPLS-TP OAM includes four procedures.

1. (Optional) Migrate services on the OptiX OSN 7500. Because slots 26 to 31 on theOptiX OSN 7500 do not support packet boards after the upgrade, the services that areoriginally carried by the boards in slots 26 to 31 need to be migrated beforehand.

2. (Optional) Replace cross-connect boards. If the cross-connect boards on the OptiX OSN3500/7500 do not support MPLS-TP OAM, replace them with proper ones.

3. (Mandatory) Switch the single-stack OAM mode (TMPLS) to the dual-stack OAM mode(TMPLS+MPLS-TP). The OptiX OSN 3500/7500/7500 II uses the single-stack OAMmode by default. Therefore, you need to switch the single-stack OAM mode to thedual-stack OAM mode. The switching is irreversible. That is, you can only switch thesingle-stack OAM mode to the dual-stack OAM mode.

4. (Mandatory) Select and switch services to MPLS-TP OAM. You select the desiredservices and switch them to MPLS-TP OAM. The switching is reversible.

1.4 Impact of the Upgrade

1.4.1 Impact on the System During the Upgrade

Impact on Services

During the switching to dual-stack OAM mode on the OptiX OSN 3500, services areinterrupted for less than 12 seconds.

During the switching from SST1PSXCSA to SST2PSXCSA on the OptiX OSN 7500, servicesare interrupted for less than 2.5 seconds.

During the service migration on the OptiX OSN 7500, services are interrupted until themigration f inishes.

Impact on Network Communications

If the equipment communicates with the U2000 through DCC channels, the communication

will be interrupted for less than 12 seconds during the switching to dual-stack OAM mode onthe OptiX OSN 3500 or for less than 2.5 seconds during the switching from SST1PSXCSA toSST2PSXCSA on the OptiX OSN 7500.

1.4.2 Impact on the System After the Upgrade

After the switching to dual-stack OAM mode on the OptiX OSN 3500, the services that runthe IGMP protocol do not support complex traffic classification. After the switching fromSST1PSXCSA to SST2PSXCSA on the OptiX OSN 7500, slots 26 to 31 do not supportpacket boards.

1.5 Precautions

The switching to dual-stack OAM mode is irreversible. You can return to thepre-switching condition only by restoring the databases that are automatically backed upbefore the switching. If you return to the pre-switching condition through databaserestoration, cold reset the cross-connect board to recover services.

Ensure power supply to the equipment where the switching to dual-stack OAM mode isbeing performed. If the equipment is powered off before the switching finishes, theequipment may enter an unexpected state and you can return to the pre-switching

condition only by restoring the databases that are automatically backed up before theswitching.In V200R013C10SPC100, the algorithm PBKDF is added, and three digestalgorithms are supported: MD5, SHA256, and PBKDF. Users can configure a digestalgorithm on the U2000. The security of the three digest algorithms from low to high isas follows: MD5, SHA256, and PBKDF2. If a stronger digest algorithm is configuredafter an upgrade, the digest information of an account added before the upgrade is stillstored in the database. You need to manually delete this account and create another one,or change the password of the account added before the upgrade.

For example, before an upgrade, digest information is generated using MD5. Supposethat an administrator account szhw exists, and the digest information of the accountpassword generated using MD5 is stored in the database. After an upgrade is performedand the digest algorithm is changed to PBKDF2, the digest information of the szhw

account password generated using MD5 is still stored in the database. You can delete this

szhw account and create a new szhw account. Then, the new szhw account's digestinformation generated using PBKDF2 is stored in the database, and the digest

information generated using MD5 is deleted.

Precautions

Services may be interrupted during inner-NE migration. To minimize the interruption time ofthe services under migration, make the target ports ready and synchronize the DCN and clockconfiguration of the source ports to the target ports before you perform service migration. To

prepare for a rollback in case of migration failure, back up the databases.

Procedure

Step 1 Synchronize the Layer 2 and Layer 3 attributes of the source ports to the target ports.

Step 2 Migrate services with the TCAT. (For details, see the help manual related to the TCAT.)

Step 3 Remove the source boards.

Step 4 Delete the logical boards of the source boards.

----End

Verification

For NNI ports, test the connectivity of MPLS tunnels using LSP Ping.

In NE Explorer, choose Configuration > Packet Configuration > MPLS Management >

Unicast Tunnel Managementfrom the Function Tree. In the right pane, click OAM

Parameters. Right-click the migrated tunnels and choose Ping Testfrom the shortcut menu.If the number of transmitted packets equals the number of received packets in a ping test, themigration is successful.

Precautions

During the replacement, services are interrupted for 2.5 seconds. To help you understand theprocedure, slot 9 is specified as active slot and slot 10 is specified as standby slot. The boardin slot 9 is the working board and the boards in slots 9 and 10 are normal. The board softwareversion of the new cross-connect board should be V200R013C10SPC100. If the board

software version of the new cross-connect board is not V200R013C10SPC100, update theboard software version immediately after the board goes online.

Procedure

Step 1 Remove the SST1PSXCSA board in slot 10.

Step 2 Delete the logical board SST1PSXCSA in slot 10.

Step 3 Add a logical board SST2PSXCSA in slot 10.

Step 4 Install an SST2PSXCSA board in slot 10 and wait until the board goes online.

Step 5 Issue the active/standby switching command to the cross-connect boards. (Services areinterrupted for 2.5 seconds during the switching.)

Step 6 Remove the SST1PSXCSA board in slot 9.

Step 7 Delete the logical board SST1PSXCSA in slot 9.

Step 8 Add a logical board SST2PSXCSA in slot 9.

Step 9 Install an SST2PSXCSA board in slot 9 and wait until the board goes online.

Verification

The active and standby cross-connect boards are online and in the normal state. There is noalarm related to incorrect board types. Services are normal.

2.8 Switching to Dual-Stack OAM Mode

The switching to dual-stack OAM mode can be performed after the operations on software,hardware, and services are completed. The switching duration varies depending on thenumber of services and the maximum duration is ten minutes. The switching causes serviceinterruption of 12 seconds on the OptiX OSN 3500 and the OAM and APS alarms on the peerNE of the OptiX OSN 7500/7500 II. The switching only enables the equipment to supportMPLS-TP and does not affect services.

Description

Switch the single-stack OAM mode to the dual-stack OAM mode on the OptiX OSN3500/7500/7500 II.

Precautions

During the switching, do not make any configuration and ensure the power supply to the

equipment. If the equipment is powered off during the switching, you can return to thepre-switching condition only by restoring the databases automatically backed up before theswitching.

The U2000 interface is locked during the switching. Do not configure the equipment using

other tools.If the LSP/PW APS is configured, ensure that the involved services are running on theworking trails. Otherwise, these services may be interrupted for over 12 seconds.

Procedure

Step 1 Check whether the services involved in LSP/PW APS are running on the working trails. InNE Explorer, choose Configuration > Packet Configuration > APS ProtectionManagementfrom the Function Tree. Check whether the services involved in LSP/PW APS

are running on the working trails.

21

Verification

The U2000 displays a successful switching message and no unexpected OAM alarm isreported.

2.9 Switching to MPLS-TP OAM

To ensure that the OAM can work properly after the switching to MPLS-TP OAM, you needto perform the switching on each node of the OAM-enabled line. Therefore, the switchingshould be performed with the U2000 in end-to-end mode.

Description

Switch the TMPLS OAM to the MPLS-TP OAM.

Precautions

The OAM detection intervals supported by Y.1711 are not consistent with those supported byY.1731. When the system encounters the detection interval inconsistencies, related alarms arereported and persist until the switching finishes. You can query the updates in detection

intervals on the U2000.

For the OptiX OSN 3500/7500/7500II in dual-stack mode, the number of supportedTMPLS-TP OAM specifications is different from the number of supported MPLS-TP OAMspecifications. To be specific, the OptiX OSN 3500/7500 supports 2k MPLS-TP OAMspecifications; the OptiX OSN 7500II supports 4k MPLS-OAM specifications, with slots 1 to8 supporting a maximum of 2.5k and slots 11 to 18 supporting a maximum of 2.5k. Therefore,the switching from TMPLS OAM to MPLS-TP OAM will fail if the number of supportedTMPLS-TP OAM specifications is larger than the number of supported MPLS-TP OAMspecifications.
