Configuring Wireless Cisco Networks and Wireless Controllers.
Hi,In case anybody else gets stuck like I did, here's the procedure we eventually knocked together for recovering our locked out 1240AG AP's:Recovery of Cisco 1240AG APThis procedure tested working 14/02/08 with an AP with the default WLAN controller password left in.Requirements:â€¢ Cisco IOS WAP image (c1240-k9-w7-mx.124-10.b.JA)â€¢ Cisco LWAPP recovery image (c1240-rcvk9w8-tar.123-7JX.tar)â€¢ Cisco LWAPP upgrade toolâ€¢ TFTP Serverâ€¢ Local PSU (not POE)Local PSU is required - process doesn't appear to work with Ethernet connected as boot doesn't stop.Power up WAP holding MODE button until LED turns Purple (approx 20 secs)Console should go through boot banners, notice no Ethernet and dump to ap: prompt.ap: IP_ADDR=a.a.a.aap: NETMASK=m.m.m.map: DEFAULT_GATEWAY=g.g.g.gap: tftp_init(message confirming tftp available should come back)Plug in Ethernet on correct vlan to see WLAN controller (i.e. a.a.a.x).ap: ether_initVia your friendly local tftp server boot off a full IP image, in this case I extracted from the full .tar file and placed it on tftp serverâ€¦ap: boot tftp://x.x.x.x/c1240-k9-w7-mx.124-10.b.JAAP should boot to ap> prompt and initialise. It may well generate r0.core and r1.core dump files as radio firmware not available.Once settled:ap> en (password in our case was the default) ap# conf tap(config)# int bvi1ap(config-if)# ip address a.a.a.a m.m.m.map(config-if)# line vty 0 4ap(config-line)# login localap(config-line)# exitap(config)# username test password aptestap(config)# exitOnce this is done the AP should be alive on the network and you should be able to ping and telnet to it and logon. Enable secret will still be the default password.Now you need to put the logon details in an ip.txt file for the Cisco WLAN recovery tool, we used the recovery tool's own tftp server and didn't enter WLC details.Click Start and Cisco tool should contact the AP, telnet in, modify the config and download the recovery image and a basic config. Once done it will reboot the AP and it will go into lwapp discovery mode. Steve.
Hi,To get the radio up you'll actually have to untar the full package (c1240-k9w7-tar.124-10b.JA.tar) as this has the firmware for the wireless:AP: tar -xtract tftp://x.x.x.x/c1240-k9w7-tar.124-10b.JA.tar flash:/The workaround we had was specifically to get it back to a 'configurable' state so that we could use the upgrade tool to convert it to a clean LAP. There is no need or capacity to use wireless for this process - it's all done over ethernet - so we did not load the radio firmware (hence the r0.core and r1.core dumps).Hope that helps ...Steve.
