What Is RADIUS-AUTH-CLIENT-MIB?

RADIUS-AUTH-CLIENT-MIB, standardized in RFC 4668, is a vendor-neutral MIB for entities implementing the client side (NAS) of the RADIUS authentication protocol, tracking outgoing Access-Request messages and incoming responses per configured RADIUS server. It exposes a per-server table of round-trip time, retransmission counts, accept/reject counts, and invalid-server-address tracking, giving a detailed operational view of authentication traffic health. Its monitoring value is centered on software/protocol-level status—detecting slow or unresponsive RADIUS servers via radiusAuthClientRoundTripTime, spotting authentication failures via rising radiusAuthClientAccessRejects, and identifying network/config issues via radiusAuthClientAccessRetransmissions or radiusAuthClientInvalidServerAddresses—rather than physical hardware sensors. It is part of the IETF RADIUS MIB family and commonly deployed alongside RADIUS-AUTH-SERVER-MIB and RADIUS accounting MIBs on the same NAS device. It is deployed on any vendor-neutral, standards-based network access server (NAS), VPN gateway, or wireless controller performing RADIUS authentication. The RADIUS-AUTH-CLIENT-MIB RFC (4668) itself obsoleted the earlier RFC 2618 definition, so implementations should be checked against the newer specification for correct object naming and semantics.

IPNetwork Monitor allows you to monitor SNMP objects defined in RADIUS-AUTH-CLIENT-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

What Can Be Monitored

RADIUS server round-trip time
access-request retransmissions
access-accept count
access-reject count
invalid server address count
configured RADIUS server port

Supported Devices

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
network access server (NAS), VPN gateway, or wireless controller

Monitoring Examples

An admin would poll radiusAuthServerTable's radiusAuthClientRoundTripTime for each radiusAuthServerIndex/radiusAuthServerAddress to detect a RADIUS server responding slowly or not at all, and watch radiusAuthClientAccessRetransmissions rising as a sign of packet loss or an unresponsive server. A spike in radiusAuthClientAccessRejects relative to radiusAuthClientAccessAccepts would indicate a wave of authentication failures, while radiusAuthClientInvalidServerAddresses climbing would reveal spoofed or misconfigured response packets arriving from unexpected sources.
