Cisco ONS 15454 and Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration Guide, R8.0
Chapter 17 Configuring Cisco Proprietary Resilient Packet Ring
Deleting an ML-Series Card from a Cisco Proprietary RPR
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
Log into Adjacent Node 2 with CTC.
Step 15
Double-click the ML-Series card in Adjacent Node 2.
The card view appears.
Step 16
Click the Circuits tab.
Step 17
Click the Circuits subtab.
Step 18
Identify the appropriate STS circuit by looking under the source column and destination column for the
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.
Step 19
Click the circuit entry to highlight it.
Step 20
Click Delete.
The confirmation dialog box appears.
Step 21
Click Yes .
Step 22
If the new node will no longer be an active node in the SONET/SDH ring topology, delete the node from
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.
Step 23
If the ML-Series card in the new node is to be deleted in CTC and physically removed, do so now. Refer
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 Figure 17-12. For detailed steps on building the
circuit, see “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 25
Start or resume a Cisco IOS CLI session for the ML-Series card in Adjacent Node 1.
Step 26
Complete the following Cisco IOS configuration for the ML-Series card in Adjacent Node 1, beginning
in global configuration mode:
Step 27
Start a Cisco IOS CLI session for the ML-Series card in Adjacent Node 2.
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.
