Dynamic Trunking Protocol (DTP) sends the VTP domain name in a DTP packet.
Therefore, if you have two ends of a link that belong to different VTP
domains, the trunk does not come up if you use DTP. In this special case,
you must configure the trunk mode as on or nonegotiate, on both sides, in
order to allow the trunk to come up without DTP negotiation agreement.
this is directly from the Doc CD,

just the VTP domain name
