1000v Removed Interface Reference

Cisco Support,

We recently swapped out 1GB interfaces in our ESX server and replaced them w/10GB cards.  When we did that, the interface IDs presented to the 1000v changed.  References to the removed interfaces still appeared when the "show port-channel sum" command was issued.  I managed to delete all but one of the unused port-channels which referenced the stale interface names.  Unfortunately, one of the interfaces is associated w/a port-channel that is actually in use (see below) and I can't delete it.  Is there a way to get rid of this stale interface reference?  Granted it isn't doing anything, but it looks sloppy.  Since the port-channel IDs are generated automatically, I can't just shuffle stuff around (at least I don't know a way of doing so).

Running version 4.2(1)SV1(4a).

Thanks in advance.

-Erik

Hey Erik,It is CSCua93737:

Hey Erik,

It is CSCua93737: Port-channel has Ghost entries even after removing ports from N1K setup

You can view the defect using this link 

https://tools.cisco.com/bugsearch/bug/CSCua93737

Workaround:

1. Create a new port-profile and associate new uplink interface to it.

2. Associate active ports to the new port-profile so that there is a new port-channel created with active uplink ports.

3. Delete the old port-channel so that all the ghost interfaces would be removed along with it. If you wish to use the same port-profile for all uplink ports, then you can move the uplink ports to the old port-profile one by one so that a new port-channel will be created using the same old port-profile.

The defect is resolved in SV2(1.1).

Thanks,

Joe
