Chapter 7 Configuring vPCs
Configuring vPCs
Configuring the Suspension of Orphan Ports
When a device that is not vPC-capable connects to each peer, the connected ports are known as orphan
ports because they are not members of a vPC. Beginning with Cisco NX-OS Release 5.2(1), you can
explicitly declare phyiscal interfaces as orphan ports to be suspended (shut down) by the secondary peer
when it suspends its vPC ports in response to a peer link or peer-keepalive failure. The orphan ports are
restored when the vPC is restored.
Note You can configure orphan port suspension only on physical ports, not on port channels.
BEFORE YOU BEGIN
Ensure that you have enabled the vPC feature.
Ensure that you are in the correct VDC (or use the switchto vdc command).
SUMMARY STEPS
1. configure terminal
