Go to WLAN > your SSID > Advanced tab. 


There should be a box on the left-hand corner to limit the amount of clients per AP.

HI fog,


The maximum number of client associations that the access points can support depends on these factors:

  •     The maximum number of client associations differs for lightweight and Autonmous IOS access points.
  •     There might be a limit per radio and an overall limit per AP.
  •     AP hardware (16-MB APs have a lower limit than the 32-MB and higher APs).



A general rule-of-thumb is ~20-30 users per AP.


But you can limit the clients that can connect to any particular AP through MAC authentication. You need to provide the MAC address of the client to the AP so that the AP can allow only those clients and restrict all the other clients that are not part of the allowed MAC address list from connecting to that particular AP.

Not really.


The wireless clients makes the decision to join whatever AP it wants.  Whether it's the furthest or the weakest AP signal, the client makes that decision. 


You can limit the number of clients per AP but this depends on whether or not you have autonomous or controller-based wireless network.

Maximum Allowed Clients or the Maximum Allowed Clients Per AP Radio option??the former  option is to limit client count per WLAN,not per AP.I don't unerstand exactly purpose about the latter.

You can't set the max client count per AP on a Unified Wireless. The only option you have on the WLC is setting the number of clients per AP on a WLAN.

According to doc,it is per WLAN based.,so I cannot make sure this funtion(Maximum Allowed Clients) is per WLAN or per APbased on specific WLAN.if it is the former,it will immediately impat the production environment.

Any changes you make on a WLAN will dissociate clients.  Changes can impact production or not, depending on how fast the devices re-auth.  Setting this value on a per WLAN, will not load balance your environment, but may cause issues if you don't have enough RF coverage.  This might force a device to look for another AP that might be at the edge of coverage.


Can you explain why you want to implement this?  Maybe there are some other options's.  Like Leo mentioned, the client devices choose what AP they want to associate to, the WLC doesn't do any of that.  You can set limits, but you might have clients that will just not connect in that area until it roams to an area where the max hasn't been reached.


Thanks,

Scott

I think the OP wants to know if its possible to configure the max client per AP overall if I understood the question right.  SO limiting 20 for example on a given access point no matter what wlan or what radio you are associated to.


Thanks,
