Chapter 17 Configuring Cisco Proprietary Resilient Packet Ring
The SPR interface and the Ethernet interfaces on the ML-Series card must be in a bridge group in order
Note
for Cisco proprietary RPR traffic to bridge the Cisco proprietary RPR.
Step 14 Log into Adjacent Node 2 with CTC.
Double-click the ML-Series card in Adjacent Node 2.
Step 15
The card view appears.
Click the Circuits tab.
Step 16
Click the Circuits subtab.
Step 17
Identify the appropriate STS circuit by looking under the source column and destination column for the
Step 18
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.
Click the circuit entry to highlight it.
Step 19
Click Delete.
Step 20
The confirmation dialog box appears.
Click Yes.
Step 21
If the new node will no longer be an active node in the SONET/SDH ring topology, delete the node from
Step 22
the ring. Refer to the "Add and Remove Nodes" chapter of the Cisco ONS 15454 Procedure Guide or the
Cisco ONS 15454 SDH Procedure Guide to remove ONS nodes.
If the ML-Series card in the new node is to be deleted in CTC and physically removed, do so now. Refer
Step 23
to the "Install Cards and Fiber-Optic Cable" chapter of the Cisco ONS 15454 Procedure Guide or the
Cisco ONS 15454 SDH Procedure Guide to install cards in ONS nodes.
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
circuit, see
Note
Start or resume a Cisco IOS CLI session for the ML-Series card in Adjacent Node 1.
Step 25
Complete the following Cisco IOS configuration for the ML-Series card in Adjacent Node 1, beginning
Step 26
in global configuration mode:
a.
Router(config)# interface pos
interface-number
b.
Router(config-if)# no shutdown
Step 27 Start a Cisco IOS CLI session for the ML-Series card in Adjacent Node 2.
"Configuring CTC Circuits for Cisco Proprietary RPR" section on page
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.
