Re: OT:Limiting number of Clients Per Access Point

Karim,

You can also have AP in LWAP mode to have only certain SSID to be allowed to
connect from cleints which is possible

from WLC- Wireless --> Go to a LWAP --> Override WLAN and select the
particular WLAN to be allowed per AP.

But since the signal gets generated from WLC to each LWAP AP it should not
be a problem irrespective of how many clients

connects to a LWAP.

Also if you restrict LWAP to a certain max.no , it may affect the roaming
clients ( Wireless phones specially).

Where are you currently located.

HTH,
Akber Mirza.
