Hello,

I'm having trouble with Voice vlan and 802.1x authentication.

On my GS1920-48HP (v4.80), 802.1X and radius is working fine.

My settings are:

Vlan 100, 110, 252 untagged (802.1x enabled)

Vlan 20 (guest vlan), untagged. And Vlan 20 PVID on all ports with 802.1X enabled.

I've configured Voice vlan 3 with OUI for my Polycom Ip phones.

All ports on vlan 3 untagged.

When I connect an Ip phone, it shows PVID 3 in the Mac Table section but the phone gets an IP adress from Vlan 20 (guest vlan).

The only way I've found to put the phone in Vlan 3 is to disable Vlan 20 on this port.

So, is Voice Vlan compatible with 802.1X and guest vlan, and if so, what could be the problem?

Regards
