Use these commands to enable MAC filtering on a WLAN:
- Enable MAC filtering by entering the config wlan mac-filtering enable wlan_id command.
- Verify that you have MAC filtering enabled for the WLAN by entering the show wlan command.
When you enable MAC filtering, only the MAC addresses that you add to the WLAN are allowed to join the WLAN. MAC addresses that have not been added are not allowed to join the WLAN.
