I have a new 3825 received last week and trying to get it set up for a demo on 6/25. I have the gig0/0 connected to my firewall and I want to create a VLAN for all devices on the other side of the router. I have followed cisco examples but they don't work. If I move to a standalone switch, it works fine. How do I configure this thing so it works properly? Are there any known problems with the module or vlans on this module?
