Blacklist a Client

To blacklist any client manually, first go to Network > Security to classify and add client mac addresses as Banned clients.

Either manually enter MAC Addresses or upload a file with the list of MACs.

Or from API, we can make PUT request under – sites/:site_id/setting/blacklist with payload of mac addresses

{"macs":["<<>>","<<>>"]}

 

Next, navigate to Network > WLANs to enable blacklisting of banned clients in the Security section

Banned clients will not be able to connect the particular SSID even after providing a correct PSK. Client events generated will be “802.11 Auth Denied”

Note: If the client is already connected to the SSID and

  • The SSID later enabled the security option to blacklist the client, or
  • The client was classified as Banned but SSID enabled the security option to blacklist later

The connected client will get disconnected from the SSID.

If a client is removed from the banned list or if the SSID disabled manual blacklisting clients, then client will be able to reconnect to SSID.
