Symptom:
MAC address table not synced properly between Nexus 3500 vPC peers, after vMotion

Conditions:
Issue seen in Nexus3500  after mac-address goes through vMotion (moving between two port-channels from Nexus3500 perspective).

Traffic should be flowing in such a way that both members of VPC should be getting traffic, to make sure both vpc peer are learning mac address via hardware new learn. After this , if the traffic flows from that mac moves via vmotion or any other mac move, then this issue can hit.
