[Asterisk-Users] OT - Cisco IP Phone and PC in diferent VLANs (with 802.1x)
Hello to all I would like to know If some of you have already configured an Cisco IP Phone (7940 or 7960) to work in a different VLAN than the PC that is connected through the phone switch? I know that this can be done with the Skinny firmware, but I dont if it works with the SIP firmware. The Cisco technical staff told me that these phones dont support 802.1x but can work as pass-through. This way I can still use the PCs with 802.1x and the phones in the same Ethernet plug. Did someone made it with the Cisco IP phones? What configuration do I need in the phones and in the switch? Thanks Joao Pereira

That's the whole idea to have them on separate vlans. You configure your phone to a tagged vlan and use untagged for your pc. That's it Wojtek PS: Just go to the network setup on your phone..

You have to configure the switchports on the Cisco switch like so: interface fastethernet 0/1 switchport trunk native vlan <your data vlan> switchport mode trunk switchport voice vlan <your voice vlan> spanning-tree portfast trunk etc. Thanks, Nicholas Kathmann, CISSP Kathmann Consulting, LLC
