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 WAC or 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.
MAC+ IMPB 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 by using
MAC. If the client is in the IMPB table and tries to
connect to the network by using MAC 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.
