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

Add an ML-Series Card into an RPR

Step 11

Click Delete.

A confirmation dialog box appears.

Step 12

Click Yes.

Step 13

Use a test set to verify that Ethernet connectivity still exists between the Ethernet access ports on

Adjacent Node 1 and Adjacent Node 2.

Note

The SPR interface and the Ethernet interfaces on the ML-Series card must be in a bridge group

in order for RPR traffic to bridge the RPR.

Step 14

If the new node is not already an active node in the SONET ring topology, add the node to the ring. Refer

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

Step 15

If the ML-Series card in the new node is not already installed, install the card in the node. 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 16

Upload the initial startup configuration file for the new ML-Series card. If you do not have a prepared

startup configuration file, manually create a startup configuration file.

Caution

Ensure the new node is configured with RPR before its POS ports are manually enabled or enabled

through the configuration file.

Step 17

Build an STS circuit with a circuit state of In Service (IS) from the available POS port on

Adjacent Node 1 to the New Node, as shown in Figure 15-8. On the New Node, use the POS port with

the interface-number that does not match the interface-number of the available POS port on

Adjacent Node 1. For example, POS Port 0 on Adjacent Node 1would connect to POS Port 1 on the

New Node.

For detailed steps for building the circuit, see the “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 18

Build an STS circuit with a circuit state of IS from the available POS port on Adjacent Node 2 to the

remaining POS port on the New Node, as shown in Figure 15-8.

Step 19

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

Figure 15-7.

Step 20

Complete the following Cisco IOS con figuration, beginning in global configuration mode:

Step 21

Start a Cisco IOS CLI session for the ML-Series card in Adjacent Node 2, as shown in Figure 15-7.

Step 22

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

global configuration mode:

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.
