It's normal behavior. Check you Procurve switch to mark all untagged frames
with VLAN2. Usually when you set port as a trunk, you should be able to set
"native VLAN" - VLAN TAG should be used if no VLAN TAG is set.
Another thing - in most switches VLAN1 is management and/or internal VLAN,
and it's not-recommneded to use it for any user traffic.
Good luck,
