Hey guys .. I Will try to make this short and sweet. At my job we are looking to implement a VOIP infrastructure. A typical infrastructure with voice and date usually will have both voice and data on a seperate VLAN. The phone will then plug into the ethernet port and the PC plug into the phone. Basically The phone becomes a trunk port for the PC) I have read that the way the phone gets place on the voice VLAN is through CDP. Appearently upon connecting to the switch the phone sends a CDP packet identifying it self and then gets placed on the Voice VLAN. I would love to attempt to put a pc on our voice VLAN. I know that yersinia has options for crafting CDP packets. Has anyone accomplished this and could some one give me a breif explanation of how I could do this.
