Googling around to see if this setup on one port is correct (it doesn't look right to me), I'm not really seeing a straightforward answer.
There is an interface with the following configuration:
! interface GigabitEthernet1/0/3 description Uplink to Server Room switchport access vlan 100 switchport mode trunk !
That's been like that for some time, and no issues that I know of. The question is, if the port is in trunk mode as opposed to access mode, then does the
switchport access vlan do anything at all?? Can it be safely removed without screwing up something else? What possible reason could those two commands be there in the first place for??
