Configure the Bridge and Roll

Bridge allows data to setup a link to another path when original path requires any maintenance. After the maintenance of the original path, Roll allows to revert the path. This chapter provides the CTC procedures to configure the bridge and roll.

Configure Bridge and Roll Using CTC

Purpose

Bridge allows setup a link between two temporary paths when the main path requires any maintenance. Rolls allows to get revert the temporary path once maintenance done of the main path. This chapter provides the CTC procedures to configure the bridge and roll.

Add an Explicit Path to an unprotected OTN Circuit for a Roll Over Using CTC

Purpose

This procedure enables you to add an explicit path to an unprotected OTN circuit for a roll over for NCS4K-20T-O-S, NCS4K-2H-O-K,NCS4K-24LR-O-S, NCS4K-2H10T-OP-KS, and NCS4K-4H-OPW-QC2 line cards, using CTC.

Adding an Explicit Path allows to roll over into the original path.

Procedure

Step 1

In the Network View, double-click the line card.

Step 2

Click the OTN > Circuit tab.

Step 3

Select a circuit from the list.

Step 4

From the Tools menu, choose Circuit.

Step 5

Click Roll Circuit. Perform the following steps in the Select a Member Circuit to Roll screen that appears.

Note

 
The roll, a circuit feature is not from the node perspective but from the CTC session perspective. If the session is closed in between, information about rolls cannot be recovered.

  1. From the Explicit Path drop-down list, choose an explicit path that you want to add to the selected circuit.

  2. Click Add to add the selected explicit path to the circuit

Step 6

Return to your originating procedure.

Perform a Manual Switch Using CTC

Purpose

This procedure enables you to perform a manual switch for NCS4K-20T-O-S, NCS4K-2H-O-K,NCS4K-24LR-O-S, NCS4K-2H10T-OP-KS, and NCS4K-4H-OPW-QC2 line cards, using CTC. Manual Switch allows the traffic to switch from the working path to the protected path.
