Chapter 15 Configuring Resilient Packet Ring on the ML-Series Card

Delete an ML-Series Card from an RPR

Step 16

Click the Circuits tab.

Step 17

Click the Circuits subtab.

Step 18

Identify the appropriate STS circuit by looking under the source column and destination column for the

circuit entry that matches the POS ports at the endpoints of the second circuit to be deleted.

The circuit entry is in node-name/card-slot/port-number format, such as Node-1/s12(ML100T)/pPOS-0.

Step 19

Click the circuit entry to highlight it.

Step 20

Click Delete.

The confirmation dialog box appears.

Step 21

Click Yes.

Step 22

If the new node will no longer be an active node in the SONET ring topology, delete the node from the

ring. Refer to the “Add and Remove Nodes” chapter of the Cisco ONS 15454 Procedure Guide.

Step 23

If the ML-Series card in the new node is to be deleted in CTC and physically removed, do so now. Refer

to the “Install the Cisco ONS 15310-CL” or “Install the Cisco ONS 15310-MA” chapters of the

Cisco ONS 15454 Procedure Guide.

Step 24

Build an STS circuit with a circuit state of IS from the available POS port on Adjacent Node 1 to the

available POS port on Adjacent Node 2, as shown in Figure 15-10. For detailed steps on building the

circuit, see “Configuring CTC Circuits for RPR” section on page 15-7.

Note

A best practice is to configure SONET circuits in an east-to-west or west-to-east configuration,

from Port 0 (east) to Port 1 (west) or Port 1 (east) to Port 0 (west), around the SONET ring.

Step 25

Start or resume a Cisco IOS CLI session for the ML-Series card in Adjacent Node 1.

Step 26

Complete the following Cisco IOS configuration for the ML-Series card in Adjacent Node 1, beginning

in global configuration mode:

Step 27

Start a Cisco IOS CLI session for the ML-Series card in Adjacent Node 2.

Step 28

Complete the following Cisco IOS configuration on the Adjacent Node 2 ML-Series card, beginning in

global configuration mode:

Step 29

Use a test set to verify that Ethernet connectivity exists on the RPR.

Step 30

Monitor Ethernet traffic and routing tables for at least one hour after the node deletion.

Stop. You have completed this procedure.

Router(config)# interface pos

interface-number

Enters interface configuration mode for the POS port at one

endpoint of the first newly created circuit.

Router(config-if)# no

shutdown

Enables the port.
