Not in my experience, no -- the native VLAN does not need to be
explicitly included in the list of VLAN IDs specified with "switchport
trunk allowed vlan" command.

From the command reference:

"allowed vlan *vlan-list* // Set the list of allowed VLANs that can
receive and send traffic on this interface in tagged format when in
trunking mode"

The keyword there being *tagged*.

VLAN 1 is a special case but I'll leave it up to you to figure that one out :-)

cheers,
Dale
