We have a couple of the 1130AGs running in autonomous mode. They are POE with Cisco power injectors on the switch end. Recently it is as if they have been "disabling" their own lan interfaces. The wireless IF stays up...mobilie users can connect to the SSID, but then never get any address from DHCP. From a wired workstation the AP does not respond to a ping. Pulling the powered ethernet cable to reset the AP does bring them back up...but it is not something we can be doing every day.
I've started monitoring the switch ports with Network Assistant to see if it is the switch that is blocking, but no data there yet. (one is attached to a cisco core switch, the other is not)
I was using a Cisco power injector, with the original access point power supply hooked up to it.
Recently (well yesterday), I've plugged this AP into a Cisco 3550 POE switch, and I'm still getting the same behavior...I'm just about ready to pitch this AP and find a new one! Before I do, I suppose I'll look for an IOS upgrade.
3550 suffers the same fate as the 2940/2950/2955. In the AP, run the command "power inline negotiation injector". An output will appear with the MAC address of the switch. Follow this by the command "power inline negotiation injector ".
Thanks leolahoo, I assume you must have meant to pleclude that first statement with a "show" however neither "power inline negotiation injector" nor "sho power inline negotiation injector" give me any results...it does appear that it is a legitimate config command however. The web gui allowed me to enter that line in the config (it auto-fills the switch mac address), so we'll see where it goes from here.
I'm not finding any newer IOS...we're running 12.4(21a)JA1...perhaps there is a reason to fallback to an older version.
Did you try this command in "configuration" mode? Following output is from an AP running 12.4(21a)JY.
AP(config)#power inline neg ? injector Power injector is installed prestandard Allow operation with prestandard high power inline devices
AP(config)#power inline neg inj AP(config)#power inline neg injector ? H.H.H MAC addr of port with power injector installed installed Confirm that power injector is installed on current port override Override saftey check. Force a power-injector on every port
I got the config set that way after your post last week. It ran fine until today 28-Oct to 03-Nov...today it dropped the LAN, yet was still powered up and advertising its SSID. Crazy. I shut / no shut on the switch port, it came back, then within 10 minutes, it dropped the LAN again. Maybe I need to test the cable....I'm out of ideas.
It appears that the IOS was the culprit. We dropped this one (and another that experienced the same symptoms) from 12.4(21a)JA1 to 12.4(3g)JA1 and have gone over a week without a failure. I'm finally feeling ready to call this "solved".
