Voice Vlan bypass 802.1x

HI,

I read some where that you can set up 802.1x so that the voice vlan bypasses 802.1x authentication.

So the processes is that the phone receives lldp or CDP packets to push it on to the voice vlan and it can send data with out any authentication process.

But I cant seem to find the document, has any one else come across this and had it working?

Cheers

With a quick google search I think something like this is what you are looking for.

This may or may-not be what your looking for but, what we have done at our shop was setup a username & password on each phone and our switchports are setup with mac address bypass which allowed our phones access to the network - this also came in handy setting up printers that didn't support 802.1x
