Extraneous commands to relieve boredom!
Actually, many times they are there in order to allow dynamic trunking
to take place. So if you're a trunk, you'll use dot1q, if you're an
access port you'll be on vlan 567.
However, since you specify you ARE indeed a trunk (switchport mode
trunk), then that really makes the access vlan command extraneous. It
won't hurt anything to be there. The switch knows what is supposed to
happen. Admins, however, may get confused about it! :)

Subject: switchport access and switchport trunk on the same port
Hi Group,
Just out of curiousity, what does the below config mean:
interface FastEthernet0/17
description *** R7 ***
switchport access vlan 567
switchport trunk encapsulation dot1q
switchport mode trunk
no ip address
Does it mean that R7 connected to switch port fas0/17 is on vlan567 and
at the same time, R7 is also a dot1q trunk? Or this config is not valid
at all? and cannot be applied under any environment.
regards - SH
