Client Limit

Information About Client Limit

This feature enforces a limit on the number of clients that can to be associated with an AP. Further, you can configure the number of clients that can be associated with each AP radio.

From Cisco IOS XE Cupertino 17.8.x onwards, client limiting is supported per AP, per radio, and per radio per WLAN.

Limitations for Client Limit

  • APs other than the Cisco Catalyst 9136 Series APs, support only 200 clients per radio. If you configure more than 200 clients for these APs, the number of clients that can be associated with the AP radios will still be limited to only 200 clients, as per the AP capability value.

  • Client limiting is supported on the Cisco Catalyst 9136 Series APs in Flex mode.

Verifying Client Limit

To verify client limit in local mode, run the following command:

Device# show wireless stats client delete reasons | sec Max
Maximum client limit reached on AP                  : 0
Maximum client limit reached on AP per wlan         : 0
Maximum client limit reached on AP radio per wlan   : 0
Maximum client limit reached on AP radio            : 0

To verify client limit in the FlexConnect central authentication mode, run the following command:

Device# show wireless stats client delete reasons | sec max
AP limiting maximum client per AP                : 0
AP limiting maximum client per AP radio per wlan : 0
AP limiting maximum client per AP radio          : 0
