Solved: Re: Cisco catalyst 3850 switch won't take command: "switchport mode trunk encapsulation dot 1q"

Hi all,

I'am working on this switch's configuration. when I typed "switchport mode trunk encapsulation dot 1q", I got an error " invavid input". I'm guessing that this model already set encapsulation type to dot 1q, and that's why the switch won't take it, right?

Please help!

According to the documents it supports both.

You are however using the wrong command, it should be -

"switchport trunk encapsulation dot1q"

ie. no "mode" keyword.

If it doesn't take that then do a "sh int <x> capabilities" and it should show you which encapsulation methods are supported.
