MAC Filtering for WGB Wired Clients
Controller software release 4.1.178.0 enables you to configure a MAC-filtering IP address for a
workgroup bridge (WGB) wired client to allow passive WGB wired clients, such as terminal servers or
printers with static IP addresses, to be added and remain in the controller’s client table while the WGB
is associated to a controller in the mobility group. This feature, activated by the config macfilter
ipaddress MAC_address IP_address CLI command, can be used with any passive device that does not
initiate any traffic but waits for another device to start communication.
