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.

Purpose
Enters global configuration mode.
Specifies the port that you want to configure and enters interface
configuration mode.
Suspends the specified port if the secondary switch goes down.
Note
The vpc-orphan-port suspend command is supported only
on physical ports, and not supported on port-channel
member ports.
Exits interface configuration mode.
(Optional)
Displays the orphan port configuration.
