Hi guys

I'm trying to convert the above Aironet unit back to autonomous mode using the appropriate IOS image which I have downloaded and placed on my TFTP server.

The problem I am having is that for the life of me I cannot get the Aironet unit to change its IP from the default 10.0.0.1.

I've booted the unit and held down the mode button for >10secs until the LED goes red, it then allows me to configure it using:

set IP_ADDR / NETMASK / GATEWAY etc
tftp_init

But I cannot ping the unit, it doesnt matter if I plug it directly into my laptop using a straight through cable, a cisco switch, anything - I cannot ping it. Even if I just let it boot using the default 10.0.0.1 address I cannot ping it unless I allow the unit to fully boot into the LAP IOS image.

If I let the unit boot fully by itself and then change the IP I can ping it no problem :confused: but of course I cannot upload the IOS image in this mode.

Anybody got any ideas?

I think it must be something I am doing wrong as I also have a 1141 LAP Cisco model that has the same issue.

These units are in my lab so its no big deal if it doesnt work without a WLAN controller but I really would like to use them if I can.

EDIT: Just to add that I successfully did this (converted back to autonomous) using a 1240AG LAP Aironet unit that I have loaned to a friend (he wanted big wireless coverage), so it must be possible with these units.

Cheers

Ok got this working now, for anyone who is interested you allow the LAP to boot normally and then:

en
debug capwap console cli
config t
int gigabit 0
ip add 10.0.0.1 255.255.255.0
end
achieve-download-sw /force-reload /overwrite tftp://10.0.0.2/c1140-k9w7-tar.124-21a.JY.tar

That's it!

The "debug capwap console cli" is what provides hidden access to the "config t" command on the LAP.

Still would be good to know how to get this to work by holding down the mode button and interrupting the boot as my 1141N doesn't have a IOS image :(

:D
