Ethernet Card Software Feature and Configuration Guide, R7.2

Chapter 17 Configuring Cisco Proprietary Resilient Packet Ring

Adding an ML-Series Card into a Cisco Proprietary RPR

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 Cisco proprietary RPR traffic to bridge the Cisco proprietary RPR.

Step 14

If the new node is not already an active node in the SONET/SDH ring topology, add the node to the ring.
Refer to the “Add and Remove Nodes” chapter of the Cisco ONS 15454 Procedure Guide or the “Add
and Remove Nodes” chapter of the Cisco ONS 15454 SDH Procedure Guide for procedures for installing
ONS nodes.

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 Cards and Fiber-Optic Cable” chapter of the Cisco ONS 15454 Procedure Guide or the “Install
Cards and Fiber-Optic Cable” chapter of the Cisco ONS 15454 SDH Procedure Guide for procedures for
installing cards in ONS nodes.

Step 16

Upload the initial startup configuration file for the new ML-Series card (see the

“Loading a Cisco IOS

Startup Configuration File Through CTC” section on page 3-10

). If you do not have a prepared startup

configuration file, see the

“Manually Creating a Startup Configuration File Through the Serial Console

Port” section on page 3-7

.

Caution

Ensure that the new node is configured with Cisco proprietary 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 17-10

. 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 Cisco Proprietary RPR”

section on page 17-8

.

Note

A best practice is to configure SONET/SDH 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/SDH 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 17-10

.

Step 19

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

Figure 17-9

.

Step 20

Complete the following Cisco IOS configuration, 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 17-9

.

a.

Router(config)# interface pos

interface-number

Enters interface configuration mode for the POS port at one
endpoint of the first newly created circuit.

b.

Router(config-if)# no shutdown

Enables the port.
