Hi,
I've seen this CDP message come up when theirs a
device attached to the same segment as your router
that speaks CDP v1 and not CDPv2. CDP v2 added duplex
support so CDP v1 didn't have it.
To get around this, you can do 'no cdp advertise-v2'
globally on your router config. This means your router
will be doing CDPv1. You can also turn off CDP on that
interface with 'no cdp run' if you don't need CDP.
