Strange wireless hiccup

[jeff.kish]

Hey all,

We had a bizarre problem this morning with our wireless APs. All APs across two management subnets went down - 58 on one and 44 on the other. They are mostly 1231G access points. During this time, they were not reachable via ping, WLSE could not see them, and they would not associate clients. After 10-15 minutes, they all came back up.

The APs are located across two attached buildings across many different 4006 and 4507 chassis switches. Each chassis homeruns back to two 6509 campus switches, which use HSRP on each VLAN interface for redundancy.

The logs on the APs, WLSE, and switches show absolutely nothing happening at this time. The APs did not lose power or reboot, and the campus switches did not show HSRP having issues. WLSE did not show the APs fail, but it does show them all coming back up.

We're trying to find the common denominator here. Does anyone have any idea what might have happened? Has anyone seen anything like this before?

Well, it's an autonomous environment using WLSE, and it didn't go down during that time. It showed that the APs were all down on those two subnets. Losing connection to WLSE wouldn't make the APs drop like they did - we had no telnet access to them and could not ping them.

The users were dropped, but they don't use AAA so there's nothing to see there.

Again, such a mystery.
