Does anyone have a simple explanation for the effect of the <voice> command as applied to Vlans on HP L3 switches, does it st up QOS or does it enable (set up) the HP WFQ mechanisim?

The voice command configures a vlan for voice and provides broadcast storm control.  It is applied at the vlan level.


vlan 1
   name "default"
   untagged 1-23
vlan 2
    name "Voice"
    tagged 1-23
    untagged 24

In this configuration port 24 would connect to the voice application server and would untag the voice packets.  Ports 1-23 would connect to the data network if a non-vlan aware device is connected.  A VLAN aware device would be able to untag the voice and pass the data to the connected host.

All voice ports must be tagged vlan's and the data must be untagged.

LLDP is configured separately for auto VLAN discovery by some IP phones.

QoS prioirty is configured on the vlan level with the priority command.

IE: vlan 10 qos priority 5

Broadcast storm control was what I was looking for, I had half an idea re LLDP so I am clear in my understanding now.
