CCNP Switch - D&D - DTP Mode
Respuestas correctas:
Explicación: Dynamic Trunking Protocol (DTP) is the Cisco-proprietary that actively attempts to negotiate a trunk link between two switches. Below is theswitchport modes (or DTP modes) for easy reference:
Mode | Function |
Dynamic Auto | Creates the trunk based on the DTP request from the neighboring switch. |
Dynamic Desirable | Communicates to the neighboring switch via DTP that the interface would like to become a trunk if the neighboring switch interface is able to become a trunk. |
Trunk | Automatically enables trunking regardless of the state of the neighboring switch and regardless of any DTP requests sent from the neighboring switch. |
Access | Trunking is not allowed on this port regardless of the state of the neighboring switch interface and regardless of any DTP requests sent from the neighboring switch. |
Nonegotiate | Prevents the interface from generating DTP frames. This command can be used only when the interface switchport mode is access or trunk. You must manually configure the neighboring interface as a trunk interface to establish a trunk link. |
