Possible solutions


Cisco Voice VLAN with 802.1X Authentication


I'm not sure it's the best answer to the question of how to make this work, but in the absence of a better answer, I figured out a way to make it work myself.

Basically, I went with the idea that if you are using what is essentially dynamic VLAN assignment (even though it's termed a voice feature), you have to use it for both the VOICE and DATA domains to get the result I was looking for.

I changed the access VLAN to a VLAN that doesn't route outside the switch, so in my case switchport access vlan 504

I then modified the policy on our NPS server to pass a VLAN assignment to computers when they authenticate.

This has the effect of putting phones or any device MAC spoofing as one without a VLAN configured being put into what is essentially a blackhole network so they can't access anything - but if configured with the correct VLAN ID, they can access the more locked down voice network.

But if a computer is attached and authenticated either directly or via the switch on the phone in the DATA domain, the switch changes the access or native VLAN to our internal network as instructed by the NPS server.

This is the result I was looking for - it just meant having to change the config on other switches that make use of the policy server in a more basic form which I was trying to avoid.
