How to configure DTP (Dynamic Trunking Protocol) Modes
Following commands sets can be used to configure different Dynamic Trunking Protocol (DTP) modes for Switch interface.
Refer folowing lessons if you are not familiar with Dynamic Trunking Protocol (DTP).
• Dynamic Trunking Protocol (DTP)
• Difference Between DTP "dynamic desirable" and "dynamic auto" Modes
How to confgure "dynamic desirable" mode
OmniSecuSw1#configure terminal OmniSecuSw1(config)#interface gigabitethernet0/0 OmniSecuSw1(config-if)#switchport mode dynamic desirable OmniSecuSw1(config-if)#exit OmniSecuSw1(config)#exit OmniSecuSw1#
How to confgure "dynamic auto" mode
OmniSecuSw1#configure terminal OmniSecuSw1(config)#interface gigabitethernet0/0 OmniSecuSw1(config-if)#switchport mode dynamic auto OmniSecuSw1(config-if)#exit OmniSecuSw1(config)#exit OmniSecuSw1#
How to confgure "trunk" mode
OmniSecuSw1#configure terminal OmniSecuSw1(config)#interface gigabitethernet0/0 OmniSecuSw1(config-if)#switchport mode trunk OmniSecuSw1(config-if)#exit OmniSecuSw1(config)#exit OmniSecuSw1#
How to confgure "trunk" mode with "nonegotiate"
OmniSecuSw1#configure terminal OmniSecuSw1(config)#interface gigabitethernet0/0 OmniSecuSw1(config-if)#switchport mode trunk OmniSecuSw1(config-if)#switchport nonegotiate OmniSecuSw1(config-if)#exit OmniSecuSw1(config)#exit OmniSecuSw1#
How to confgure "access" mode
OmniSecuSw1#configure terminal OmniSecuSw1(config)#interface gigabitethernet0/0 OmniSecuSw1(config-if)#switchport mode access OmniSecuSw1(config-if)#exit OmniSecuSw1(config)#exit OmniSecuSw1#
How to confgure "access" mode with "nonegotiate"
OmniSecuSw1#configure terminal OmniSecuSw1(config)#interface gigabitethernet0/0 OmniSecuSw1(config-if)#switchport mode access OmniSecuSw1(config-if)#switchport nonegotiate OmniSecuSw1(config-if)#exit OmniSecuSw1(config)#exit OmniSecuSw1#
