[c-nsp] Nexus 5k NX-OS upgrade issues VPC access port.

Hey All,



Just wanted to check something off with the subject matter experts.



Last night did an upgrade on my pair of nexus 5k from 5.0.2N1.1 to 5.0.2.N2.1 and ran into and issues where after one device was rebooted one of my VPC failed until the second Nexus one was upgrade.



I am pretty certain the issue was that that VPC was not running as a edge port which caused STP to be inconsistent and causing a type 1 global on the VPC taking it down.



So the question is, if I change this port-channel to type edge will this fix the issues as I would like to do another pair Friday night.
