case format.
Command Mode
Global Configuration
User Guidelines
Use this command to override the format of MAC addresses sent in the
Calling-Station-Id (attribute 31) and the User-Name (attribute 1) for
authentication requests for ports configured for MAC based 802.1x
authentication (MAB).
This command is only valid for 802.1X authentication.
This command does not override interface configuration for attribute 31 or
attribute 1.
Command History
Introduced in version 6.3.0.1 firmware.
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.
