vpc orphan-port suspend

sucanushie

Hi Folks,

Quick question regarding vpc orphan-port suspend command.

Would you use this command on individual trunk links down to an ESX host?

I have two Nexus 3548 running VPC up to a pair of Cat 4500's.

It depends. If you take a look at your network topology, you can see wether this command is needed or not.

The main goal of this command is to prevent orphan ports (ports which countains vPC vlans, but is not part of a vPC) from remaining functional after a failure by suspending the interface. This will cause your dual-homed servers to activate fault tolerance and re-pin the vm's vnics to the other physical port(s).

Take a look at this design guide, p 125.
