Suspending Orphan Ports On A Secondary Switch In A Vpc Topology - Cisco nexus 5000 series Configuration Manual

Suspending Orphan Ports on a Secondary Switch in a vPC Topology

This example shows how to enable the vPC peer gateway:
switch(config)# vpc domain 20
switch(config-vpc-domain)# peer-gateway
switch(config-vpc-domain)#
Suspending Orphan Ports on a Secondary Switch in a vPC Topology
You can suspend a non-virtual port channel (vPC) port when a vPC secondary peer link goes down. A non-vPC
port, also known as an orphaned port, is a port that is not part of a vPC.
When a port is configured as an orphan port, the port will flap. This occurs because the system reevaluates
Note
whether the port can be brought up, given the constraints of the orphan port. For example, MCT needs to
be up and election needs to be complete.
Before You Begin
Enable the vPC feature.
