Cisco also suggests limiting the number of SSID's. The Vocera troubleshooting guide mentions that if you have five you should remove one to improve things. This is always the dilemna ...when to add a new one and when to lump things onto an existing one.

Included they strongly suggested that you use a dedicated SSID for phones only.

We are using a Pre-Shared Key (PSK) on that SSID today. A question comes to mind, will you use a cached user/pw for the credentials on the device itself or use, say a 7 year device certificate instead (something we are pondering….)? We are having the same thoughts. I’d add that when you use a dedicated SSID, you can gain some “knobs” on the controller’s configuration that you can tweak for say a particular make/model that is problematic (EG: Cisco 7925G) Thanks, Chad Chad D Burnham Director of Telecommunications University Technology Services University of Denver 2100 S.

I am thinking about using my wpa2 secure SSID for them. Anybody got any caveats or suggestions?
