Procurve 5406zl VoIP Vlan Issue

We are starting to get a VoIP network - though the VoIP config and servers are being supplied via our Telco.

The handsets are Polycom 330 phones that will be linked into HP Desktops (7900's and 8000's). The issues that we are having is that the PC's no longer get a PXE (Altiris) boot server or proper IP address.

As per below, PC's should be part of Vlan 1, VoIP phones and POE are working.

This is our current running config:

Re: Procurve 5406zl VoIP Vlan Issue

In order for phones and computers to work in a single port, the port must be "tagged" in the voice vlan and "untagged" in the data vlan.

So either the phone must be set to tagged, or start out as untagged and gets its config via a tftp download and reconfigure itself to speak tagged, then the pc will work, as it only speaks untagged (generally anyway).

A port can only be untagged in 1 vlan, while can be tagged in multiple vlans - simultaneously.
