6.2(5.15)

Description (partial)

Symptom:
one of the mac addresses points to a blank switch ID

Conditions:
Primary peer VPC leg is down. On secondary, mac move happens from VPC leg to orphan port. Given a scale setup of 14k MAcs, 216 VLANs race condition happens where the secondary syncs the local swid to primary instead of ES SWID. This creates confusion in primary to display the blank in sh mac.
