Example
This example globally configures the format of the MAC address sent in the
Calling-Station-Id attribute and the User-Name attribute when using MAC
based authentication to IETF lower case. It also configures interface Gi1/0/1
to use MAB. MAB must be configured on the switch in an active
authentication list, IEEE 802.1X must be configured, and a RADIUS server
must also be configured.
