Access Point keeps disconnecting and reconnecting

Hello,

  I have a network of 300+ access points and a zone director to manage. I have one AP that keeps disconnecting automatically. It stays on for about a minute then disconnects for several hours. It does this several times every day.

My aim is to locate the AP so I can check the cable / replace the AP. My problem is that I have no way to locate it. I have tried to use the MAC address to search my switches mac address table but it is gone too quickly.

Does anyone have any ideas to locate a disconnected AP?

Many thanks,

Tim Franklin

The ZD Monitor/Access Points page should provide the last known IP address of this mis-behaving AP.  From the top/right of your ZD WebUI is a Toolbox, with Network Connectivity, offering Ping and Tracert, that might lead you thru the routers/switches to help find it.

Hello,
  Thanks for the input. We statically assign the IP so I have that, although switches only work on the layer 2 (MAC) so you cannot use IP to locate a device. Also it all falls under the same network so it doesn't hit a router. 

Do you know if Ruckus has any history reporting tool that I can see trends? This may help identify when it will come back on next.

Hi Tim,

Do you have MESH enabled on the ZD?
If yes, then i think from mesh neighbour list you can see which all AP's see this problematic AP which will narrow down possible area and its switch where this AP could be mounted/installed...

I know this will not help entirely but adding another step which possible could..

Hi,
You can add external syslog to switches and get logs about ports going up and down. Usually there must be only a few. Also,  you know MAC address, and it will be also visible in the log.
You also can allow debugging on ZD (under administration/ diagnostics/ debug logs, choosing only AP section,  but it still  may create a lot of data, so external syslog is a better idea. To analyse ZD debug log you need support account and use proper tool on support site.

Assuming you have an IP address: On a linux system try doing a "ping -a" (audible)
This will give you an audible alert when the AP is responding to pings.
If you don't have a mac address (and the linux system is in the same subnet as the AP)  then (in another window) do an "arp -a <IP.Ad.dr.ess>".

Then (assuming you have managed switches) open a CLI on a switch in your environment + type (for cisco switches) "show mac address address ma:ca:dd:re:ss:of:ap". (or the equivalent command for your switch)

Start with the switch that your controller is connected to.
find out what switch is connected to the port where this AP's MAC Address lives.
Then try this same command (while your "ping" command is beeping at you) on the next switch and the next until you arrive at the switch and port where your missing AP is connected.
