Yes,

It is not public, sorry. You can reference some Yersinia and related papers about manipulating VLANs.

Subject: Re: Re: Anonymous access to Voice VLAN using CDP

It doesnt seem feasible to have completely seperate networks in my opinion. The idea is to implement in a cost effective manner and with as little work as possible. I find it odd that data can be trunked through the phone from the pc but in turn the ideal solution is to keep them completely seperate. I guess I can understand your point but like I said this is not the way our VoIP solution has been implemented. My question was "does anyone know of any source code out there that allows you to spoof a CDP packet to allow a machine access to a voice VLAN.?"
