A stack switch for performing pass-through forwarding operations,
assigning stack switch identifiers to a plurality of stack switches,
temporarily disabling supervision messages exchanged by stack switches,
and electing a primary master stack switch is disclosed. In the
pass-through mode, the stack switch automatically forwards packets
between stack ports independent of their destination address to maintain
connectivity between adjacent stack switches while conventional bridging
and routing operations are disabled. The sequential identifiers are also
preferably assigned in accordance with the sequential position of the
various stack switches to better reflect the topology of those switches.
The switch is also preferably adapted to temporarily disable the
transmission of supervision messages between stack switches to prevent
re-assignment of network management functions when switch resources are
low. The switch may execute a stack switch identifier numbering scheme
based on the time the switch became operational.
