Wireless Access

Hi, I'm hoping someone can help me here, I have a 3200XM ROW Controller that I need re-ip and move to a different vlan and I do not have any access to the console port.
The controller also doesnt have a loopkback address.  Is there any way I can do this successfully via WebUI and/or CLI without losing access to the controller prior to being able to successfully reboot to the new configuration?

A.) Current IP & VLAN config

controller-ip vlan 1

ip default-gateway xxx.xxx.3.254

interface gigabitethernet  1/0
        description "GE1/0"
        trusted
        trusted vlan 1-4094
        no spanning-tree
!

interface vlan 1
        ip address xxx.xxx.3.252 255.255.252.0
!

interface vlan 2
        ip address xxx.xxx.80.42 255.255.255.0
        operstate up
!

interface vlan 6
        operstate up
!

B.) Desired Future IP & VLAN Config

#show controller-ip
Switch IP Address: xxx.xxx.80.42
Switch IP is from Vlan Interface: 2

ip default-gateway xxx.xx.80.1

interface gigabitethernet 1/0
        description "GE1/0"
        trusted
        trusted vlan 1-4094
        switchport mode trunk
        switchport trunk native vlan 2
        switchport trunk allowed vlan 2,6
        no spanning-tree
!

interface vlan 2
        ip address xxx.xx.80.42 255.255.255.0
        operstate up
!

interface vlan 6
        operstate up
!

The problem is that you have to do a write mem for it to survive a reboot.  You probably won't be able to get to that, because you will be cut off from the GUI as soon as you change the ip address, unfortunately..

Thanks CJoseph,

Would the addition of a loopback address help me to accomplish this?

I eventually managed to gain access to the controller console port via laptop and remote access, which was my initial road block to re- Iping it.  So Im all set now. 

CJoseph, Thank you for your assitance in answering my query.
