VLAN with ASA 5500 appliance

We have a CME 4.0 setup and getting ready to configure VLAN's for Voice and data. Our LAN gateway is ASA 5500 security appliance. Do we need a router behind the ASA appliance to do VLAN trunking?

or can the ASA appliance do VLAN trunk?

We use 4503 Chassis for Core and 3560 switches for other buildings.

We use 3845 Router with CME 4.0. Do we make this the LAN gateway and configure default GW on this router as the ASA appliance?

Thanks

Re: VLAN with ASA 5500 appliance

Hi,

You may configure the very CME Router as the InterVLAN Trunking device. If the phones are directly connected to the CME Router, nothing has to be done to the ASA configuration. Remember to configure the CME Router and the phones´ports in the switch as trunk ports.

Regards.
