AP-70 not communicating with controller anymore.

What do I need to do to get my AP to talk with the controller again. It is pulling an IP address from DHCP but keeps rebooting. I ran a wireshark capture and it appears that it is talking to the controller but the controller isn't responding.

On the controller's commandline, type "show log system 50" to see if that access point is doing anything.  What version of ArubaOS is this?

Re: AP-70 not communicating with controller anymore.

We lost power to our cisco switch that provides power to the AP and when power was restored it wouldn't communicat anymore. We have two othe AP's that are fine. I tried connecting a separate AP 70 and getting the same results. Here is the output of the command you suggested:

 

Oct 9 16:29:42 :311002:  <WARN> |AP B888.R2060.AP01@sapd|  Rebooting: sapd_old_msg_send: Unable to contact switch Oct 9 16:29:43 :303086:  <ERRS> |AP B888.R2060.AP01@nanny| Process Manager (nanny) shutting down - AP will reboot! Oct 9 16:30:51 :303022:  <WARN> |AP B888.R2060.AP01@nanny|  Reboot Reason: AP rebooted Fri Dec 31 16:05:10 PST 1999: sapd_old_msg_send: Unable to contact switch

Re: AP-70 not communicating with controller anymore.

Does it keep saying that over and over again, or does it only say it a couple times?

 

It looks like it can find the controller and it can send syslog to it, but it cannot send papi (UDP 8211 or GRE protocol 47), which is needed to bring up wireless Virtual APs.  If it is only a couple of times, it is an artifact of being down when the switch was down.  if it is repeated, check to see if you have a firewall blocking UDP 8211 and GRE protocol 47.

It is happening repeatedly. Is the firewall specific to certain AP's because two of my AP's are fine?

It is not specific to APs.  If there is nothing blocking the traffic, try plugging that AP70 into another switch.

Re: AP-70 not communicating with controller anymore.

I did try an AP in the same switch with an AP that is working and getting those same results. I was thinking it was a licensing thing but I have 4 licenses with only 3 AP's connected to my network.

Okay, now try the reverse.
