How to Blacklist Wired Clients based on ACL hits


How to Blacklist Wired Clients in 8.x controllers/network based on ACL hits?


When a client is blacklisted in the controller, the client is not allowed to associate with any AP in the network for a specified amount of time. If a client is connected to the network when it is blacklisted, a de-authentication message is sent to force the client to disconnect.

This feature is designed to support for tunnel based RAPs


Configure a session-acl:

ip access-list session blacklist

any host any deny blacklist log


Add the ACL to the specific role:

(Aruba7210) [mynode] (config) #user-role authenticated

(Aruba7210) [mynode] (config-submode)#access-list session blacklist position 3


Configuration command for setting the blacklist timer:

  (Aruba7024) ^[mynode] (config) #aaa authentication wired

  (Aruba7024) ^[mynode] (Wired Authentication Profile) #blacklist-time 600


To delete a blacklist user manually from the blacklist-table:

  (Aruba7210) [mynode] (config) #delete-wired-blacklist-user mac b4:b5:2f:8d:cc:96

  Wired user with mac b4:b5:2f:8d:cc:96 removed.


Show command for checking wired blacklist clients

  (Aruba7210) [mynode] (config) #show wired-blacklist-clients
