Sorry to self reply - but I took some more time and read through what Bjarne was saying in his post.  He had also made a change in the base types file for the cisco-wlc8.  Doing this does seem to have gotten rid of the garbage characters (fingers crossed).

However, an unfortunate side effect is that now a CDP neighbor line is coming in with the current hold timer (which changes every second)… So back to registering a diff every time we run…

This is absolutely not an elegant solution, but I put another line into the same spot Bjarne was talking about in ciscowlc.pm to ignore “wired0”.  That seems to be the only line in the config that otherwise references “wired0".  Rancid runs now and doesn’t register a config change every time.

Neverthless, I’m not a huge fan of hand hacking code like this.  I’d still love to hear from anyone that has a Cisco WLC version 8.x humming along nice in RANCID.  If part of my issue is that I’m actually on Mobility Express then fair enough.  Just want to see if there’s something I could be doing better to handle this particular device.

Thanks.
