Is there a best practice on the number of ssid's per AP ? I was working with a test ssid on some AP's in a building. Everything seemed ok while the ssid was on the AP, but after removing it from all the AP's I was testing, I pretty much had to reboot all the AP's I was working with as they stopped passing client traffic consistently. Management wise the AP's were up and you could connect, but no traffic consistently until rebooting the AP. Only reason I asked about the number of ssid's as that was the only thing I modified recently.
I just had to delete two SSIDs during a lab test (20 mins ago) I didn't see any issues with the clients under test on the last SSID I still had running. You should contact the GTAC, someone should be able to review your logs and configs.
