HP V1910 ProCurve Voice VLAN auto mode possible with LLDP and no OUI mask?

Question

On a ProCurve V1910 I have configured Voice VLAN as follows in network settings using the Web UI:

1. LLDP -> Global Setup -> LLDP Enable -> Set Enable
2. VLAN -> Modify Port -> Select ports -> Set Link Type to Hybrid, leaving default production VLAN as untagged membership
3. Voice VLAN -> Setup -> Set Voice VLAN Security to [Disable]
4. Voice VLAN -> Port Setup -> Select Ports -> Port Mode [Auto] and Voice VLAN Port State to [Enable], enter the voice VLAN ID in the textbox and [Apply]

If I now connect the IP phone, in the LLDP settings the phone gets recognized as Telephone with Voice media type.

Snippet from LLDP neighbour port details:

System capabilities supported : Telephone 
System capabilities enabled   : Telephone
[...]
Media policy type        : Voice
Unknown Policy           : No  
VLAN tagged              : Yes
Media policy VlanID      : 300

I would now expect the switch to recognize that it should enable VLAN 300 as tagged VLAN.

However, for that to work I first need to add my IP phones OUI to the "Voice VLAN" configuration. Only if I add the OUI the switch recognizes the phone and everything works as expected. (Yealink phone on VLAN300, forwarding the production VLAN on the PC port)

Am I missing something? What's the point of LLDP if I need to add the OUI for Voice VLAN to work?

Answer 1

So I figured out what to do to fix this.

First, open a CLI console to the switch (this functionality doesn't seem to be supported in the Web UI)

Then enter these commands:

_cmdline-mode on
* choose Y to ignore warning and enter password: 512900

system-view
undo voice vlan security enable
lldp enable
voice vlan track lldp
save

Now the OUI records arent required for Voice VLAN to work.
