RANCID and Cisco Catalyst Switches

[Pierotti, Phil]

Cisco Catalyst Switches effectively modify the configuration every time a
port changes link state - by tweaking the active "spantree portcost" and
"spantree portvlancost".

Does anyone know/have a hack/tweak to make RANCID ignore these "differences"
in the configurations? 

On a switch with end-users connecting/disconnecting/rebooting (ie working
normally) you'll see a change every single time RANCID runs.

Thanks,
Phil P
