Claim 11:
12. The system of claim 11 wherein the switches are further configured to:
in response to detecting a failure of the communication path from the first switch, cause the switch device of the first data cable to connect a second network interface to the first communicatively coupled server, the second network interface providing a communication path from the second of switches to the first communicatively coupled server;
send, by the first and second switches, a second request packet;
receive, by the first communicatively coupled server, only the request packet sent by the second switch based on the first data cable connecting the second network interface to the first communicatively coupled server;
receive, by the first and second switches, a second reply packet from the first communicatively coupled server, wherein the second reply packet is generated based on the request packet sent by the second switch;
based on data contained in the second reply packet, determine, by the first and second switches, that the second switch is an active switch; and
based on its status as the active switch, forward, by the second switch to the first communicatively coupled server, tunneled data packets received from the first switch.
