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 Dell-AAA?

Dell-AAA is a Dell proprietary MIB that manages Authentication, Authorization, and Accounting (AAA) configuration on Dell network switches, controlling how RADIUS, TACACS+, local user, and line/system password authentication methods are enabled and prioritized. It exposes largely configuration and capability-flag data rather than traffic counters, indicating which AAA methods are supported and enabled on the device. Its monitoring value is verifying the software-level security configuration state of the switch, confirming whether RADIUS or TACACS+ authentication is actually enabled versus merely supported, and whether a fallback like local-user or always-success authentication is active (a potential security risk if left on). It is a self-contained vendor MIB but conceptually parallels the standard SNMPv2 security model and RADIUS/TACACS+ protocol concepts it configures. It is deployed on Dell PowerConnect/Networking switches in enterprise environments to audit and manage centralized authentication settings, where Dell-AAA SNMP monitoring helps confirm no insecure fallback method is left enabled.

IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-AAA. 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

  • Dell PowerConnect/Networking switch

Monitoring Examples

An admin would check rlAAARadiusEnabled and rlAAATacacsEnabled to confirm which centralized authentication backend is active, and specifically monitor rlAAAAlwaysSuccessEnabled, since this bypass mode granting automatic success would be a serious security misconfiguration if left enabled in production. rlAAAMibVersion and the various *Supported flags (rlAAARadiusSupported, rlAAALocalUserSupported) let a management system confirm feature availability across a fleet of Dell switches before pushing a consistent AAA policy via rlAAARetries and related settings.

What Can Be Monitored

  • RADIUS authentication enabled
  • TACACS+ authentication enabled
  • local user authentication enabled
  • always-success bypass state
  • system/line password authentication state
  • AAA retry count

How to Use in IPNetwork Monitor

Example using rlAAALineConsFailedLogins OID:

Select a Dell PowerConnect/Networking managed switch (AAA: RADIUS/TACACS+/local authentication) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type rlAAALineConsFailedLogins into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the number of last consecutive failed logins. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
