WLC Block Client Association

fdharmawan

Hi Guys,

 

On my environment, I want to block several client's MAC addresses. The goal is to prevent those clients to connect to any SSID that are being broadcasted by the WLC.

 

I did some research. An article said that, it is possible by inserting the MAC addresses to disabled clients list (Security -> Disabled Clients -> Manual Disable). But some other article said that it is possible by inserting the MAC addresses on CLI by issuing "config exclusionlist add 12:34:56:65:43:21" command.

 

My question is, which one of those two method that will work to prevent the client to connect to any SSID? Or maybe those two methods actually are the same thing?

And if I apply the config, will the AP go down for a while? Like when altering some element on an SSID.

 

I haven't tested any since my environment is operational 24/7 and I don't have any lab to test or some sort. I just don't want to make a mess by bringing the WiFi down since WiFi is our main connection and the availability of cables are minimal.

 

Thank you.

Hi,

Information: 

Client exclusion might be enabled or disabled on a per-WLAN basis. By default it is enabled with a timeout of 60 seconds.

You need to disable the clients by adding in the list.

no it will not impact to AP.

 

Info: us etheis command to disbale it: config config <MAC address> Name

Hi Sandeep,

 

By adding on which list? On the CLI on or the GUI one? Or are those two refers to the same list?

 

And command that you're talking about, what is that for?
