DTP (Dynamic Trunking Protocol) is a Cisco proprietary protocol that is used to negotiate the use of trunk links between switches. Here are the three true statements about DTP:
DTP is a Layer 2-based protocol. DTP operates at Layer 2 of the OSI model and is responsible for negotiating the encapsulation type (802.1Q or ISL) to be used on a trunk link. This negotiation takes place between two switches that are connected by a trunk link.
DTP is enabled by default. DTP is enabled by default on most Cisco switches, but it can be disabled if needed. When DTP is enabled, it will attempt to negotiate the use of a trunk link with the connected switch.
DTP is a proprietary protocol. DTP is a proprietary protocol developed by Cisco, which means it is not a universal protocol that can be used on non- Cisco equipment. This can cause compatibility issues when connecting Cisco switches to switches from other vendors.
In summary, DTP is a Layer 2-based protocol that is enabled by default on most Cisco switches. It is a proprietary protocol that is used to negotiate the use of trunk links between switches.
