Symptom: ARP is not being resolved for the server. The GW receives the ARP request and it replies. The server never receives the ARP reply. Conditions: There is a VPC in place with Nexus 93180 with singled home FEXs. Server has active/standby interfaces. When the ARP reply reaches the VPC domain to Peer 2, it is forwarded via Peer-link to Peer 1. This one drops the packet instead of sent it to server via FEX. This should not be expected.
