Description: Provides IETF RADIUS accounting client statistics including requests, responses, and server communication counters per RFC 2620.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is RADIUS-ACCT-CLIENT-MIB?

RADIUS-ACCT-CLIENT-MIB is a vendor-neutral IETF standards MIB (RFC 2620) defining management objects for devices acting as clients of the RADIUS accounting protocol, such as network access servers, routers, and wireless controllers that report user session accounting data to a RADIUS server. It exposes counters and status for accounting request/response traffic, retransmissions, timeouts, and per-server communication statistics rather than physical hardware sensors. In terms of software health monitoring, it is used to track the operational status of the RADIUS accounting client process itself, including round-trip response times and error counts that reveal whether the accounting subsystem is functioning correctly. It depends conceptually on the RADIUS protocol standard and is commonly deployed alongside RADIUS-AUTH-CLIENT-MIB and the corresponding server-side MIB. It is typically found on network access servers, VPN concentrators, and wireless LAN controllers that use RADIUS for accounting. Engineers implementing or auditing this functionality typically reference the RADIUS-ACCT-CLIENT-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in RADIUS-ACCT-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.

Supported Devices

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
network access servers, routers, VPN gateways, wireless controllers

Monitoring Examples

An administrator would poll counters such as accounting request, response, retransmission, and malformed-response counts per configured RADIUS accounting server (indexed in a per-server table keyed by server address) to verify the client is successfully logging user sessions. A rising retransmission or timeout counter combined with a flat response counter would indicate the accounting server is unreachable or overloaded. Round-trip time objects reveal latency degradation before it causes session logging failures.

What Can Be Monitored

accounting requests sent
accounting responses received
retransmissions and timeouts
malformed responses
round-trip time per server
