i have a trunk line between 2 switches.on one side of the switch i do the below configuration
( switch-1)
# int fa 0/0
#switchport trunk encap dot1q
#switchport mode dynamic desirable
#end
on the other end ( switch-2)
# int fa 0/0
#switchport mode dynamic auto
# end
will the trunk line work even if i do not configure the encapsulation on the 2nd switch
Solved! Go to Solution.

Hi
It will enable a trunk. There are switches with implicit dot1q , now you can check the port status and Operational Trunking Encapsulation through: show interface fa0/0 switchport.
If it is configured as dot1q it will create a trunk. Now a best practice is configure both ends with the same config.

Hello
Just like to add to julio comments -
In the interface configuration the switchport trunk encapsulation dot1q will take precedence of the dynamic command, but the trunk will come up as negotiated trunk ( DTP)
