Are you getting the error: Command rejected: An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode?
I first got this error when I was trying to setup a Cisco 3560. To be more precise

Acevirgil de Ocampo says
A switch port configured as “Auto” trunk encapsulation will result “Command rejected” and cannot be configured to trunk mode.
To resolve the issue:
“switchport trunk encapsulation dot1q” command should come first before issuing the command “switchport mode trunk”.
Example:
switch(config)#interface fa0/1
switch(config-if)#switchport trunk encapsulation dot1q
switch(config-if)#switchport mode trunk
Your good to go! 🙂
