Why not L3 your network instead? Use VxLAN for 'interior' core, and vPC
at the edges. And migrate away from STP completely? Build from the
core outwards.

Look at the OMD version of Nagios. It provides good alerting, plus has

How about www.cisco.com/go/fn
That is the feature navigator.Other than that, I think you'd have to
find some CiscoLive presentations.

List Members:
Can anyone make a recommendation on a self-contained STM-4/STM-1 mux: STM-4
is used for back haul, and STM-1s are split out for local use.
It appears as though a 7206VXR G2 won't accept STM-4 natively, so I need
something to split a few of the STM-1's out.
Ray.
