trunk between switches

hi every body!

i just want to confirm the following:

sw1(config-if)#switchport

#switchport mode dynamic desirable

sw2(config-if)#switchport

# switchport mode dynamic desirable.

Will the trunk form? or do we need to use the command: switchport trunk encapsulation negotiate on both switches?

thanks a lot!

Re: trunk between switches

switchport trunk encapsulation negotiate is the default setting on a switchport, thus there isn't a need to enter such command.

A switchport will form a trunk under the following modes.

Desirable<->Desirable

Desirable<->Auto

on<->on

Please refer to table 12.4 from this URL
