Chapter 17 Configuring Cisco Proprietary Resilient Packet Ring
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
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
Cisco ONS 15454 SDH Procedure Guide to install ONS nodes.
If the ML-Series card in the new node is not already installed, install the card in the node. Refer to the
Step 15
"Install Cards and Fiber-Optic Cable" chapter of the Cisco ONS 15454 Procedure Guide or
Cisco ONS 15454 SDH Procedure Guide to install cards.
Upload the initial startup configuration file for the new ML-Series card (see the

enabled or enabled through the configuration file.
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
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
section on page
Note
Build an STS circuit with a circuit state of IS from the available POS port on Adjacent Node 2 to the
Step 18
remaining POS port on the New Node, as shown in
Step 19 Start or resume a Cisco IOS CLI session for the ML-Series card in Adjacent Node 1, as shown in
Figure
Step 20 Complete the following Cisco IOS configuration, beginning in global configuration mode:
a. Router(config)# interface pos
interface-number
b. Router(config-if)# no shutdown
Start a Cisco IOS CLI session for the ML-Series card in Adjacent Node 2, as shown in
Step 21
Complete the following Cisco IOS configuration on the Adjacent Node 2 ML-Series card, beginning in
Step 22
global configuration mode:
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.

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.
