See SSID twice

[pbogaerts]

Hi,

We have installed two WLC's in SSO type 5520.

The customer says that he sees an SSID and an SSID with the same name and between brackets standby.

So like i.e.

SSID : Data and second SSID : Data(standby) and this on the same band 5GHz

From where comes the second standby SSID.

Can someone explains this, did a search but could not find the reason

Thanks,

Peter

Hello,

I have never seen this. 

So, if you do a show WLAN summary on the active WLC you will see it listed? os is the second SSID only seen on the stand by?

This happened after SSO was configured? if so, any logs you can share?

Hi,
You see just 1 SSID in the GUI, it is a replacement van two 5508 in N+1, now two 5520 in SSO.
The SSID is seen by the client as (standby)
