	So, if you're not using cisco switches, (ie:
something to absorb those CDP packets), i've seen issues.. esp if
you have a 7920 on the same broadcast domain..

	the 7960's don't like seeing cdp packets from
anyone else.  At least you can turn it off in the 7920 in the
hidden menus, and it stays off.

	something to watch out for.. you may be able to
configure your switch to blacklist/sink the multicast mac address
that the packets get sent to.
