[Asterisk-Users] OT - Cisco IP Phone and PC in diferent VLANs (with 802.1x)

[Joao Pereira]

And about the 802.1x ?
The phones can work as passthrough and force the PC to use 802.1x ?
What configuration do we put in the switches? Do we put the switch as 
"access" (with 802.1x) or "trunk" (without 802.1x) ?

Thanks
Joao Pereira
