I have a site with an AP that has disconnected several times now, seemingly randomly (it's happened after hours, with zero client connections). Since it's offline I am not able to pull a trace log using the EWC console. I have had the folks at the site go and reboot the access point to get it back online. They have reported that when it's in this state, there is a single amber light (pretty much like when power is first applied).
Is there anything I can do in the way of troubleshooting a failed and rebooted AP? Is there any sort of memory dump that would survive a reboot? I noticed that there is a /tmp/log/ap.logLastReboot.gz file. But if I gzip -d the file, and cat the ap.logLastReboot file, all it says is "---WARNING: ap-log is not valid (size 2298819153, tail 2261266449)".
This may be indicative of a completely different problem or bug.
For the time being I have ssh'd into the AP and run:
cset sshtimeout 0
tail -f /tmp/log/ap.log[/code]And now I am just waiting for it to fail again and hoping that it dumps something to the ssh session before it bombs out. Although I suspect this is all over a flaky cable-modem connection that's occasionally dropping packets.
Anyone have other ideas?
My AP is a 3825i, and I am running with version 10.11.02.0032.
