MAC Authentication Bypass Configuration

MAC Authentication Bypass (MAB) enables hosts or clients that are not 802.1X capable to join
802.1X-enabled networks. It is not required to enable 802.1X authentication prior to enabling MAB.
The following example is a basic MAB configuration on a Catalyst switch:
switch(config)# interface GigabitEthernet2/1
switch(config-if)# authentication port-control auto
switch(config-if)# mab
For additional information on configuring MAB authentication, see the configuration guide for your
access switch.

Verifying the MAB Configuration

To verify the MAC Authentication Bypass configuration, use the show authentication interface
command.
switch# show authentication interface gigabitEthernet 2/1
Client list:
Interface
Gi2/1
Available methods list:

Runnable methods list:

To verify that the port has successfully authenticated, use the show mab interface command.
switch# show mab interface gigabitEthernet 2/1 details
