Re: OT trunking to HP ProCurve 4000M

The ProCurves don't implement a "native" VLAN per se, although the box
starts out with all ports "untagged" and in VLAN 1. As you add VLANs, you
can arbitrarily designate any one of them as "untagged" on a given port. The
rest of the VLANs must be tagged on that port. Or you can specify all of the
VLANs as "tagged." An untagged VLAN would correspond to the native VLAN on
the Cisco-side.

Cisco does not tag the native vlan. HP probably does.

Either have Cisco tag the native vlan (dot1q-all-tagged) or use a fake vlan.
