Re: Design issue

You're losing me on the module failing. You lose the SUP on one of
your switches and you lose that switch. If you have a port channel
and lose a port, the other one should work. If you lose connectivity
to both cores non-VSS... I'm not really sure. If the core is tied
together with trunked switches, one core would "find it's way back to
root" via BPDUs riding an access switch. If you're running VSS, it's
recommended to run Dual Active Detection, in which case VSS (port
channel) link would go down, the ports on one of the switches would
all get set to admin down.

Note, there's a lot smarter dudes on this forum than me, I just
happened to be one to stick my neck out and offer some advice.
Obviously, no one knows your environment better than you, white board
it out and try and break it.

Cheers!
