Claim Text:
1. A method, comprising: receiving a first address resolution protocol (ARP) packet at a first shared Ethernet adapter (SEA) coupled to a first switch; parsing, by the first SEA, a first MAC address corresponding to the first ARP packet; transmitting, in response to receiving the first ARP packet, the first MAC address to a second SEA coupled to a second switch; storing the first MAC address at the second SEA; detecting that the first SEA has transitioned from a primary configuration to an inactive configuration and that the second SEA has transitioned from a backup configuration to the primary configuration; and responsive to the detecting, transmitting a reverse ARP packet to the second switch coupled to the second SEA notifying, the second switch that the first SEA has transitioned to an inactive configuration and that the second SEA has transitioned to an active configuration; and configuring the first switch to forward any subsequent packets to the second switch rather than the first SEA.
