    we use Clearpass for guest authentication. In case we need to permanently prevent a mac address from connecting to the guest SSID, 

    Is it the right approach if we modify the endpoint status to disabled client?

    You'll need to write policy around handling the attribute, but don't deny the client device.  Allow the connection and assign a role that doesn't allow any traffic to flow, otherwise you'll see the client reconnect constantly.

    But disabled clients also don't have access to the network, correct?

    That particular flag is used by a MAC auth service to determine if authentication is allowed or not.  Any other service you would still have to write policy around unknown/known/disabled.  The problem is, most any situation where a decision on a  MAC address is going to be the allow/deny choice is probably going to result in the device attempting to connect multiple time.  Rather than constantly having to reject the connection, allow the connection, deny all traffic, and place them in a blackhole VLAN.
