Hello,
I am experiencing a very tricky problem over Nexus 7K configured with VPC as described in the KB: CSCsy16113
Symptom: The vPC stays in the suspended state on a device when both vPC peer devices power cycle
and only one of these devices comes back online.
This problem is known in both release 4.0(2) and release 5.0(3) and should have been resolved since release 5.
I've updated from release 4.0(2) to release 5.0(3) but the problem is still present.
here a shoot of sh vpc:
N7K-DCM-LAN-B# sh vpc
Legend:

vPC domain id : 201
