EXTREME-MAC-AUTH-MIB

Description: Extreme Networks MIB for MAC-based authentication (MAC Auth) policies, controlling port access based on MAC address credentials.

Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

EXTREME-MAC-AUTH-MIB is an Extreme Networks proprietary MIB for managing MAC-based authentication (MAC Auth) on switch ports, controlling network access based on the source MAC address of connected devices rather than 802.1X credentials. It exposes a table of authenticated client entries per port along with control objects to initialize or force reauthentication of a given client. Its monitoring focus is software/security status: operators can see which client MAC addresses are currently authenticated on which ports, detect authentication failures, and trigger reauthentication when troubleshooting access issues, which is important for tracking unmanaged devices (printers, IP phones, IoT) admitted via MAC-based policy. It is a self-contained Extreme Networks vendor extension for port-based network access control, complementary to but distinct from the IEEE 802.1X-based standard MIBs. It is deployed on Extreme Networks access switches in environments using MAC-based NAC for devices that cannot perform 802.1X supplicant authentication. Engineers can download the EXTREME-MAC-AUTH-MIB file directly to load it into their MIB browser.

A network administrator would poll extremeMacAuthClientTable/extremeMacAuthClientEntry to see which extremeMacAuthClientAddress values are currently authenticated on each port, spotting an unexpected or unauthorized MAC address gaining network access. If a legitimate device (e.g., an IP phone) fails to authenticate after a policy change, the admin can invoke extremeMacAuthClientReauthenticate to force a fresh authentication attempt, or extremeMacAuthClientInitialize to reset that client's authentication state entirely. Repeated authentication failures logged against a single port's client entry point to either a misconfigured MAC allow-list or a faulty end device.
