Interesting; you are quite right: I tried moving a sub-interface between
"encapsulation dot1q 6" and "encapsulation dot1q 3800", and the output
changed:

Switch(config-subif)#int gi4/8.6
Switch(config-subif)#enc dot 6
Switch(config-subif)#do sh pla har cap vl       
VLAN Resources
  VLANs: 4094 total, 130 VTP, 58 extended, 22 internal, 3884 free
Switch(config-subif)#enc dot 3800        
Switch(config-subif)#do sh pla har cap vl VLAN Resources
  VLANs: 4094 total, 130 VTP, 58 extended, 23 internal, 3883 free
Switch(config-subif)#

So if I use VLAN 6, I have an extra VLAN. I'm scheduling a service
window a.s.a.p.! :-)

(Or more realistically the output from the command is wrong...)

Regards,
Peter
