I'm curious if any Cisco users out there are experiencing or have
experienced what we're seeing on our campus. This past summer we
installed 3502i's in all of our residence halls - approximately 500
total. Ever since the students have moved in, we will get messages from
WCS stating that "AP XYZ" is down and disassociated from the
controller. When I check out the AP, the uptime is fine, but the
"CAPWAP join time" is for like 30 seconds, or however long it took me to
check.
We've tracked this and it is totally random as to what AP will drop,
which makes troubleshooting this very tough. The log on the AP isn't
helpful. I'm working with TAC who suggests that keepalives are getting
missed. I'm not sure why that would be the case since we have another
500 or so APs on the admin side that very rarely drop. Adding to that,
when the students left for break, the AP drops stopped. They came back,
and sure enough, the drops start up again.
I will say that the AP always joins back immediately, but for the time
that it does drop A) I'm sure connectivity is affected in that area and
B) we get an email.
Anyone experiencing this?
Thanks,
-dan
