Configured two 5548 Nexus switches with VPC and a 4506 as an access switch with a port channel trunk uplink. All looks OK but when I fail one of the links from the 4506 connectivity is lost for 30 - 45 seconds. Almost like spanning tree re-converging. Didn't expect that to happen. Anyone know of any possible configuration / bug issues that might give these results?
This is not expected though you can expect a minor disruption for the active flows on the link.
Ensure you have both the links added and working correctly in the port-channel.
