Description: Manages IEEE 802.1X port-based network access control on Dell network switches.

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-DOT1X-MIB?

Dell-DOT1X-MIB is a Dell private MIB for configuring and monitoring IEEE 802.1X port-based network access control on Dell network switches. It exposes per-session authentication statistics, guest VLAN and unauthenticated VLAN configuration, and user-based VLAN assignment settings for ports running 802.1X. Its monitoring focus is software/protocol status rather than physical hardware: rldot1xExtAuthSessionStatsTable/Entry and rlDot1xAuthSessionAuthenticMethod reveal which authentication method succeeded (or is in use) per session, while the guest-VLAN and unauthenticated-VLAN objects show whether a port has fallen back to a restricted VLAN because 802.1X authentication failed or was never attempted. This MIB depends on and complements the IEEE 802.1X standard and typically coexists with the vendor's core VLAN and port MIBs. It is deployed on Dell access-layer switches in enterprise networks enforcing NAC (network access control) policy at the switch port. Engineers can download the Dell-DOT1X-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-DOT1X-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

  • Dell network switch (802.1X access-layer)

Monitoring Examples

An admin would walk rldot1xExtAuthSessionStatsTable/rldot1xExtAuthSessionStatsEntry to see per-session 802.1X authentication statistics and check rlDot1xAuthSessionAuthenticMethod to confirm which method (e.g., EAP type) was used. rldot1xGuestVlanVID and rldot1xGuestVlanPorts show which ports have fallen into the guest VLAN, and rldot1xUnAuthenticatedVlanTable/Entry with rldot1xUnAuthenticatedVlanStatus reveals ports operating in the unauthenticated VLAN. A rising count of ports landing in the guest or unauthenticated VLAN would indicate a wave of 802.1X authentication failures, e.g., from a misconfigured RADIUS server or expired credentials.

What Can Be Monitored

  • per-session 802.1X authentication method/statistics
  • guest VLAN assignment/ports
  • unauthenticated VLAN status
  • user-based VLAN assignment support

How to Use in IPNetwork Monitor

Example using rldot1xAuthMultiEapolFramesRx OID:

Select a Dell PowerConnect/Networking managed switch (802.1X port access control) 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 rldot1xAuthMultiEapolFramesRx 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. The number of valid EAPOL frames of any type that have been received by this Authenticator. 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 sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
