UCS VIF Link State stays up even after disabling port

NixG80

Level 1

I've setup a vNIC for one of our blade servers with failover enabled for redundancy. In order to  test the FI failover for the vNIC I go ahead and disable the upstream port for FI-A. This should tell UCS to failover to FI-B with little to no downtime. This does not happen as it should. Looking at the equipment's VIF paths it seems as even though the upstream port for FI-A is disabled the virtual circuit is still showing as a link state of up. Any ideas why the failover might not be working as it should? Thanks for the help.

So you have disabled all uplink ports on FI-A that carry the vlans related to the VNIC you are trying to test fail over for?

If you have a typical VPC type setup, you'll probably need to disable ports on both upstream switches going to FI-A,,, or just disable the uplink port-channel on FI-A itself.

 

It's also possible you have a network control policy applied to the vnic/vnic template, that has the 'action on uplink failure' set to 'error' instead of 'link down'

The default setting is linkdown.

Kirk,
Yes, all uplink ports have been disabled on FI-A. Also, the network control policy was set to default on the vnic template with the action on uplink failure set to link down. It is still not failing over to FI-B like it should.
