Dynamic Trunking Protocol DTP Definition: Dynamic Trunking Protocol (DTP) is a Cisco proprietary networking protocol used to negotiate, establish, and maintain trunk connections between networking devices.
Dynamic Trunking Protocol (DTP) is a Cisco proprietary protocol used for negotiating trunking on a link between two networking devices, such as switches. DTP facilitates the automatic negotiation of trunk links, where multiple VLANs can pass between devices. It enables switches to establish if a trunk link is needed and to negotiate the appropriate parameters for trunking, such as VLAN configurations, encapsulation methods, and terms for the exchange of VLAN information.
