Question : Problem: VLAN Tunnel

I have two Cisco WS-C3548-XL switches that are connected by fiber optic cable.  I want to create a VLAN on port 48 of one switch and ports 47 and 48 on the other switch and connect them together.

I have a situation where I have two wireless access points on opposite ends of the office that I want to put on their own VLAN so I can connect them to the DMZ port on the firewall.

Thanks for any help!

Answer : Problem: VLAN Tunnel

Telnet to the device and login (if so required, I hope it is) then do the following, in order

enable
configure terminal

Then execute the aforementioned config. Web GUI, no idea. I don't use ASDM and never will.
