Voice Vlan compatibility with 802.1x authentication ?
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

Hi @Millbull
The Voice VLAN has higher priority than 802.1X and guest VLAN.
I did a local lab and my IP phone can get the correct IP address from voice VLAN interface.
May I know if your configuration is the same as your provided before? If so, I will check your configuration.
Please also help to check:
1. Does there have any VLAN mis-configuration in your topology?
2. Does your IP phone set static IP address or static VLAN?

Hi @Melen,
Thank for the reply.
The IP phone uses dhcp.
I will send you a private message with the config file and tech-support.
Regards
