I've attached my config from my 2811. There are a couple things I can't figure out.
Why is VLAN1 up / down?
cao-va_colh#sh ip int brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 172.18.4.1 YES NVRAM up up
FastEthernet0/1 unassigned YES NVRAM administratively down down
FastEthernet0/1/0 unassigned YES unset up down
FastEthernet0/1/1 unassigned YES unset up down
FastEthernet0/1/2 unassigned YES unset up down
FastEthernet0/1/3 unassigned YES unset up down
FastEthernet0/1/4 unassigned YES unset up down
FastEthernet0/1/5 unassigned YES unset up down
FastEthernet0/1/6 unassigned YES unset up down
FastEthernet0/1/7 unassigned YES unset up down
FastEthernet0/1/8 unassigned YES unset up down
Serial0/2/0:0 unassigned YES NVRAM up up
Serial0/2/0:0.500 63.x.x.x YES NVRAM up up
wlan-controller1/0 172.19.4.1 YES NVRAM up up
Vlan1 172.20.4.1 YES NVRAM up down
NVI0 unassigned NO unset up up
The second and more pressing matter is this sh ip account.
cao-va_colh#sh ip accou | excl 63.123.252.

Why is a wired, LAN device going through the AP-Manager? All wired clients should get 172.18.4.x addresses. All wireless clients should get 172.19.4.x addresses and WAPs should get 172.20.4.x addresses. Since WLAN1 is up / down, I understand why WAPs aren't getting 172.20.4.x but why would a wired device be using the AP-Manager as it's source to the internet?
