User Guidelines
Use this command to override the format of MAC addresses sent in the
Calling-Station-Id (attribute 31) for Access-Requests for ports configured for
MAC based 802.1x authentication or MAB.
This command is only supported for 802.1X authentication.
This command does not override the per RADIUS server configuration for
attribute 31. Use the mab request format command to configure formatting
the User-Name attribute.
Command History
Introduced in version 6.3.0.1 firmware. Updated in release 6.5.0 to remove
formatting of the User-Name attribute.
Example
This example globally configures the format of the MAC address sent in the
Calling-Station-Id 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.
