It's nothing to worry about.  It just means that the Cisco box is asking
your machine to negotiate another protocol.  In this case, the Cisco is
asking if you'd negotiate Cisco Discovery Protocol.  Your Linux box tells
the Cisco you don't understand that protocol.  That's it.  It's not hurting
anything, and it doesn't mean that anything is wrong.  You can safely 
ignore the message.
