Delete an ML-Series Card from a Cisco Proprietary RPR
Step 22 Complete the following Cisco IOS configuration on the Adjacent Node 2 ML-Series card, beginning in
global configuration mode:
Step 23 Use a test set to verify that Ethernet connectivity exists on the Cisco proprietary RPR.
Step 24 Monitor Ethernet traffic and routing tables for at least one hour after the node insertion.
Stop. You have completed this procedure.
Delete an ML-Series Card from a Cisco Proprietary RPR
An existing Cisco proprietary RPR might need an ML-Series card deleted. This can be done without
taking down data traffic due to the Cisco proprietary RPR wrapping capability and ring architecture.
The following example has a three-node Cisco proprietary RPR with three STS circuits connecting the
ML-Series cards. Two circuits will be deleted. The Cisco proprietary RPR will wrap traffic on the
remaining circuit with as little as a one ping loss. The third node and ML-Series card are then deleted
and a new STS circuit is created between the two remaining cards.
Figure 17-11 shows the existing three-node Cisco proprietary RPR with all three STS circuits and spans.
Figure 17-12 shows the Cisco proprietary RPR after the third node, circuits, and spans are deleted and
the new STS circuit and span are added.
a. Router(config)# interface pos
interface-number
Enters interface configuration mode for the POS port at one
endpoint of the second newly created circuit.
b. Router(config-if)# no shutdown Enables the port.
