What Is CTRON-WAN-MIB?

CTRON-WAN-MIB is a Cabletron (Enterasys) enterprise MIB that manages WAN interface configuration on Cabletron routing devices, covering encapsulation settings, line parameters, and circuit status, including specific support for DDS (Digital Data Service) leased-line configuration. It exposes objects for backup-interface enablement on a WAN interface and a DDS configuration table describing per-circuit line settings. From a monitoring standpoint it functions mainly as a WAN circuit/interface configuration and failover-readiness check: wanInterfaceEntryBackUpIfEnable tells an operator whether a backup path is enabled for a given WAN interface, directly relevant to detecting whether a primary-circuit failure would actually trigger failover as intended. It complements the standard IF-MIB and DS1/DS3-style circuit MIBs, since Cabletron's WAN objects describe circuit-specific parameters layered on top of standard interface counters. It is deployed on Cabletron/Enterasys routers with WAN interface modules (e.g., leased-line DDS circuits) connecting branch or remote sites. Engineers can download the CTRON-WAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CTRON-WAN-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

  • Cabletron/Enterasys router with WAN/DDS interface modules

Monitoring Examples

An administrator would check wanInterfaceEntryBackUpIfEnable on a primary WAN interface to confirm backup-path failover is actually enabled before relying on it during an outage. Walking ddsConfigTable/ddsConfigEntry entries shows the configured line parameters for each DDS circuit, letting the admin verify a circuit's settings match what the carrier provisioned. A WAN interface with backup disabled that then goes down would explain a site losing connectivity instead of failing over as expected.
