This MIB module defines a portion of the SNMP enterprise MIBs under Enterasys Networks' enterprise OID pertaining to MAC-Authentication. This MIB was designed to be used for authentication using source MAC addresses received in traffic on ports under control of MAC-authentication. The security afforded by this approach is neither the primary concern nor intent of this MIB. Rather, this MIB provides a convenient method of associating policy with MAC addresses and applying that policy when the MAC address appears on a pre-approved port in the network. The term MAC-Authentication is used because an authentication backend mechanism is used to allow the MAC onto the network, as well as provide authorization information to the switch.
