May be you didn't see it.
But my statement is true in CatOS, see below
SWMNWNAA122> (enable) show trunk
* - indicates vtp domain mismatch
Port Mode Encapsulation Status Native vlan
-------- ----------- ------------- ------------ -----------
3/1 nonegotiate dot1q trunking 2
Port Vlans allowed on trunk
-------- ---------------------------------------------------------------------
3/1 2-3,100
Port Vlans allowed and active in management domain
-------- ---------------------------------------------------------------------
3/1 2-3,100
Port Vlans in spanning tree forwarding state and not pruned
-------- ---------------------------------------------------------------------
3/1 2-3,100
SWMNWNAA122> (enable) set vlan 4 3/1
