Hello forum,
We have just deployed WLC and WCS with couple of lightweight AP.
We decide to employ MAC filtering to restrict wireless client.
We noticed a SERIOUS problem, once we removed a mac address from the WCS and apply to controllers, Wireless client with that mac address are still able to access(ping,dhcp) the network even though its mac is removed from the currnt local mac filter after around 10mins???
Is there a know bug to this issue? or it requires some moment for the changes to take effect.
