Transition LNW170 in UNPROT mode to PROT

Procedure 11-40.5: Transition LNW170 in UNPROT mode to PROT

Overview

Use this procedure as an example to transition two unprotected LNW170 circuit packs participating in an existing ERP to protected mode with ERP.

This procedure assumes that two unprotected LNW170s are already installed in the node, participating in ERP, and you are transitioning them to protected LNW170s.

Note that the ERP ring must be a VCG ring to transition to protected LNW170 circuit packs.

Step

Make sure that the ring is in the idle state.

From the Navigation menu, select View → Data → ERP. Select the circuit pack associated with the ERP.

TL1 command: rtrv-erp.

In the ERP display, verify that the ERP Instance State is ENRB (No Request (RPL blocked).

Note the VLAN ID and Maintenance Level.

Login to one of the nodes adjacent to the node being transitioned. Shut down the link connected to the node being transitioned.

From the System View, select Configuration → Equipment. Expand the circuit pack details.

For a VCG port, expand the VCG details.

Set VCG Membership to Disabled for both Input and Output Direction.

In the Apply To: drop-down box, select All Tributaries, This VCG.

Click Apply, then click Close.

Result:

This node signals SF.

Disable and Delete the ERP on the unprotected LNW170(s).

From the System View menu, select Configuration → Data → Create/Modify/Delete ERP.
From the Create/Modify/Delete ERP screen, select Disable for the ERP State.
Check the Delete box to delete the ERP.
Click Apply, then click Close.

DELETE EXISTING LAG

If any LAG groups exist on the unprotected LNW170s, use the TL1 dlt-lagrp command to modify the LAG , or select Configuration → Data → Create/Modify/Delete LA Group from the System View menu. Select the circuit pack.

Important!

All but the last port must have been previously removed from the LAG before you can delete the LAG.

Click in the Delete box for the LAG being deleted. Click Apply, read the warning message, then click Yes to execute the command. Click Close to exit.

On the companion LNW170 circuit pack, remove cross connection and virtual switches.

NOTICE

Service-disruption hazard

Changing the Slot Protection State of the LNW170 100/1G FXS circuit pack causes a circuit pack reset which may take up to several minutes to complete and disrupt service.

Wait until the circuit pack reset is complete before performing additional provisioning.

Set the Slot Protection State to PROT.

From the System View, select Configuration → Equipment, select the companion LNW170 100/1G FXS circuit pack, then click Select. Verify/set VLAN Tagging Mode to SWITCHED. Provision the Slot Protection State to PROT.

Result:

The services and L2 provisioning on the working circuit pack ports 1, 2, 5, and 6 are transferred to LAG groups 1, 2, 3, and 4, respectively.
The same port numbers on the companion slot are members of those LAG’s.
Any ports not in use on the working circuit pack remain so but are members of their preassigned LAG’s.
A protection group is created and the working circuit pack Switch State becomes Active-WAN.

Move/install the SFPs, cables, hairpin VCG cross-connections to connect LAG across the LNW170s. Remove any unused SFPs, if required.

Reconfigure ERP on both the LNW170s VCGs to include the newly created link between the two circuit packs.

Set ERP State to ENABLE.

Reference:

From the System View menu, select Configuration → Data → Create/Modify/Delete ERP.

If required, from the System View menu, select Configuration → Data → Create/Modify/Delete LA Group and change the Active/Standby Mode.

Enable the link that was shutdown in Step 3.
