SSID disappear

We have a place,where put a AP93.Sometimes the SSIDs are all disappear.When it's happened,i try show ap active,bss-table,arm rf-sum,and ping it,look like all good.But,i can't see any ssids even change an AP.

I try use an AP by the same config,It's always work.

I have check controller log and airwave log,i think it don't have any error.

 

Have anyone some suggestion?

 

Thanks!

Re: SSID disappear

 

Do you mean this happens when you move the AP to another location ?

 

Can you try the following command and see what BSSIDs are attached to that AP :

show  ap  bss-table ap-name <apname>

show  ap  debug system-status ap-name <apname> | begin iwconfig

show datapath tunnel ipv4 <ap-ipaddress>

 

 

Thank you

The AP 93 is a single radio AP and can only be on 1 band at any given time. When you run show ap bss-table, what phy type is your SSID using?

Is your client 5 GHz (a/n/) capable? Could it be set to a single band in the wireless card properties?

After you confirm the other commands from my previous post you should check the following :

Is there any flags when you do the show ap database | include <APNAME> ?

Is the AP changing APgroups ?

Are the LEDs for the g/a radio on the AP are lid

Is the SSID configure to be hidden under the SSID profile ?

And to make sure there's nothing misconfigured or missing do show profile-errors</APNAME>
Thank you

The flag is "Rc2".

AP no changing APgroups,and i put an ap at other place look like don't have issue.

When i user AP93,the LEDs "PWR" "ENET""11B/G/N" are light.

NO.

I think no,this group have some VAPs other group is also have,but others don't have issue.

 

It's not happened yet,so if it happened i will try your command.

 

thanks for your help!

Did you meant to configured that AP as a Remote AP? , Rc2 means that is coming up a rap

Re: SSID disappear

When you get chance run this command :

show datapath tunnel ipv4 <ap-ipaddress>

This will tell you which gre tunnels for SSIDs are making it to the AP
