Cisco's model is a bit different.

In small environment's the HP (and other low-end switch) model works
fine, but in larger environments with even dozens if not hundreds of
VLANs, the Cisco one works much better overall.

In Cisco, you can have exactly one untagged VLAN per trunk port.
Everything else is assumed to be tagged on a trunk port.

(ignoring the fact that vlan1 magicly gets untagged by default on many models)

interface GigabitEthernet1/1
switchport trunk allowed vlan 1-3
switchport trunk native vlan 1
switchport mode trunk

The same on HP Procurve no matter whether you configure tagged or untagged.

Ahhh... that explains a problem I had a while back.
