If I set the "switchport mode trunk" command on an interface, but don't specify the "switchport trunk allowed vlan X,X" command as well, what vlans are allowed through?  Also, if this same interface has the command set on it "switchport access vlan 2", does that do anything or is it a non factor since the interface is set to trunk mode?
