BSSID Counters

BSSID counters

A BSSID counter is a statistical feature that

  • retrieves BSSID statistics when a client is associated with a WLAN for every configured interval

  • requires configuration in the controller per AP profile to enable or disable BSSID statistics on the access points, and

  • is disabled by default.

BSSID counter limitations

BSSID counter is not supported on the Cisco Aironet 1800 series APs and Cisco Catalyst 9100 series APs.

Enable BSSID statistics and BSSID neighbor statistics (CLI)

Enable BSSID statistics collection and neighbor statistics reporting to monitor AP performance and neighboring wireless networks.

Procedure

Step 1

Enter global configuration mode.

Example:

Device# configure terminal

Step 2

Enter the AP profile configuration submode.

Example:

Device(config)# ap profile ap-profile-name

ap-profile-name is the profile name of the configured AP.

Step 3

Enable BSSID statistics.

Example:

Device(config-ap-profile)# bssid-stats

Use the no form of the command to disable the feature.

Step 4

Set the BSSID stats frequency timer.

Example:

Device(config-ap-profile)# bssid-stats bssid-stats-frequency bssid-timer-seconds

Example:

Device(config-ap-profile)# bssid-stats bssid-stats-frequency 40

BSSID statistics frequency timer is in the range of 1 to 180 seconds.

Step 5

Enable BSSID neighbor statistics.

Example:

Device(config-ap-profile)# bssid-neighbor-stats

Use the no form of the command to disable the feature.

Step 6

Set the interval at which BSSID neighbor statistics is sent from the AP.

Example:

Device(config-ap-profile)# bssid-neighbor-stats interval bssid-interval

Example:

Device(config-ap-profile)# bssid-neighbor-stats interval 50

The BSSID neighbor stats interval is in the range of 1 to 180 seconds.
BSSID statistics and BSSID neighbor statistics are now enabled and will be collected at the specified intervals for network monitoring and analysis.

BSSID statistics verification on the controller

To verify the BSSID statistics on the controller, use these commands:

  • show wireless stats ap name ap-name dot11 24ghz slot 0wlan-id<wlan-id> statistics 

    Device# show wireless stats ap name APXXXX.6DXX.58XX dot11 24ghz slot 0 wlan-id 18 stat
