Description: Manages Cisco Small Business RADIUS server configuration for 802.1X and management authentication.

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 CISCOSB-RADIUSSRV?

This is a proprietary Cisco Small Business (CISCOSB) MIB for configuring the device's built-in RADIUS server used for 802.1X port authentication and management-plane AAA. It exposes server enable state, accounting/authentication UDP ports, shared secret keys (plaintext and MD5), trap enables for accounting/authentication success/failure events, and RADIUS server-group definitions tied to VLANs. Its monitoring relevance is centered on software/security configuration status, confirming the RADIUS service is enabled, correctly ported, and that trap notifications for authentication failures are active, which are key indicators for detecting authentication problems or attacks. No explicit external MIB dependency is stated, though it complements standard 802.1X port-authentication MIBs on the same device. It is typically deployed on Cisco Small Business series switches in SMB networks needing local RADIUS-based 802.1X authentication without a dedicated external AAA server. Engineers can download the CISCOSB-RADIUSSRV file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCOSB-RADIUSSRV. 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

  • Cisco Small Business switch (CISCOSB series)

Monitoring Examples

Checking rlRadiusServEnable confirms the local RADIUS service is administratively enabled, while rlRadiusServAcctPort and rlRadiusServAuthPort verify it is listening on the expected UDP ports (typically 1813/1812). rlRadiusServTrapAuthFailure being disabled would mean authentication failures go unreported to the NMS, and rlRadiusServGroupTable's rlRadiusServGroupVLAN shows which VLAN a given RADIUS server group is associated with, useful for confirming per-VLAN authentication policy is correctly scoped.

What Can Be Monitored

  • RADIUS server enable status
  • accounting/authentication UDP port configuration
  • shared secret key configuration
  • authentication success/failure trap enable state
  • RADIUS server group VLAN association
