3750 Stack reset on Master failure

wwilkinson · ‎02-23-2006

Anyone seen a stack of 3750-48PS-S's reload when the master fails? We have a few stacks, each with 3 identical 3750's in the stack, and when the master switch (switch 1 priority 15) was powered down, the stack crashed and reloaded. This only happened once on each of the stacks and we could not replicate it again. The version IOS on the switches is Version 12.2(25)SEB4 (c3750-ipbase-mz.122-25.SEB4).

The Master switch acts as gateway for the stack.

So once the master is failed then stack completely will not be reachable.

Replace the failed master switch and download the IOS from net and copy those IOS to slave switches in the stack using

the steps
