Description: D-Link 3100 AAA MIB providing authentication, authorization, and accounting configuration and status management objects.

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 DLINK-3100-AAA?

DLINK-3100-AAA is a D-Link private MIB for the DGS/DES-3100 series managed switches, covering Authentication, Authorization, and Accounting (AAA) configuration for device management access. It exposes configuration objects controlling which authentication methods are enabled (RADIUS, TACACS+, local user database, system or line password), retry counts, and TACACS+-specific settings. As a configuration/security-status module, it lets an administrator verify the software configuration governing who can log into the switch and by what method, which is critical for confirming that management access is locked down as intended rather than left in an insecure fallback mode. It is a vendor-private MIB that parallels concepts from the standard RADIUS/TACACS+ protocols but does not appear to import a standard IETF AAA MIB directly. It is typically deployed by network administrators managing centralized authentication for a fleet of D-Link 3100-series access switches. Network engineers evaluating or troubleshooting this functionality can download the DLINK-3100-AAA file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DLINK-3100-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

  • D-Link DES-3100/DGS-3100 series managed switch

Monitoring Examples

An operator would check rlAAARadiusEnabled, rlAAATacacsEnabled, and rlAAALocalUserEnabled to confirm which authentication backends are active, along with rlAAARetries for the login retry limit. The rlAAAAlwaysSuccessEnabled flag is particularly worth monitoring, since if left enabled it would mean the switch grants access regardless of credential validity -- a serious security misconfiguration. Checking rlAAASystemPasswordEnabled versus rlAAALinePasswordEnabled clarifies whether the switch is relying on a shared system password or per-line passwords for fallback authentication.

What Can Be Monitored

  • AAA method enabled status (RADIUS/TACACS+/local)
  • authentication retry count
  • system/line password authentication mode
  • always-success authentication flag

How to Use in IPNetwork Monitor

Example using rlAAALineConsFailedLogins OID:

Select a D-Link DES-3100/DGS-3100 series managed switch (AAA) 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.
