Don't forget switchport trunk allowed vlan and switchport trunk native vlan configurations.

? for TunerX,

Is it necessary to issue the "no switchport mode access", I thought that issuing the "switchport mode trunk" would be enough.

Does this depend on whether or not the port was in its default LAN1 state or if it had been assigned a VLAN using the 'switchport mode access' command?

TIA for the reply...

He said " no switchport mode access vlan" this will take it off a vlan & allow you to place it in trunk mode. You cannot trunk while a vlan is in place on an Interface.
