IMPB + JWAC Mode

This mode adds an extra layer of security by checking the IP
MAC-Binding Port Binding (IMPB) table before trying one
of the supported authentication methods. The IMPB Table is
used to create a 'white-list' that checks if the IP streams being
sent by authorized hosts have been granted or not. In the
above diagram, the Switch port has been configured to allow
clients to authenticate using either JWAC. If the client is in
the IMPB table and tries to connect to the network using
either of these supported authentication methods and the
client is listed in the white list for legal IP/MAC/port
checking, access will be granted. If a client fails one of the
authentication methods, access will be denied.

Description
Block - The client is always regarded as an un-authenticated.
Local - The Switch will resort to using the local database to authenticate the client. If the client
fails on local authentication, the client is regarded as un-authenticated. Otherwise, the client is
regarded as an authenticated.
Permit - The client is always regarded as an authenticated. If the guest VLAN enabled, the
client will stay at the guest VLAN, otherwise, it will stay at the original VLAN.
