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.
