Abstract
One embodiment of the present invention provides a switch. The switch includes a management mechanism and a configuration mechanism. During operation, the management mechanism is configured to operate the switch in conjunction with the partner switch as a single logical switch. The configuration mechanism is configured to assign a virtual switch identifier to the logical switch.
