2. THe external interfaces could be used to connect to a gig capable router supporting a wan.

Re: cat4006 Pls give a solid answer

Hi,

Can you elaborate on the uses of the 2 GBIC uplink ports which are on the Supervisor module?

I have a dumb question, which I haven't found the answer for yet: If we are not using fiber, where is the connection to the PIX (which connects to our outside router)? I understand the uses of the console and management ports. We currently have 2 48-port switching modules and have ordered 3 more. Are these modules connected as a hub: port 1 to port 48 of the one above?

Thanks.

4006 with L3 module does support IRB.

http://www.cisco.com/warp/customer/473/28.html

The above document explains the architecture and shows some sample config.

For IRB, you would configure bridge-group under the port-channel interface and external gig sub-interface and use BVI to route between various bridge groups upto 16.

Please open TAC case for further assistance
