What Is ERI-DNX-OCTAL-HIGH-SPEED-MIB?

ERI-DNX-OCTAL-HIGH-SPEED-MIB is an Eastern Research Inc. (ERI) enterprise MIB for the "octal high-speed" port module of the DNX multiplexer/digital cross-connect platform, managing multiple synchronous serial WAN interfaces (e.g., V.35/X.21/EIA-530 style) on a single card. It exposes a configuration table (oHSConfigTable/Entry) with per-port objects for port address/resource, port name, administrative status, operating mode, line speed, electrical interface type, clocking source, and network loopback control. It is used to monitor and configure the hardware/operational status of each high-speed serial port — checking oHSCfgStatus for port up/down state and oHSCfgClock/oHSCfgNetLoop for clocking source and loopback test mode — which is essential for diagnosing WAN link problems on multiplexed DNX serial cards. There is no notable dependency on external standard MIBs evident beyond ERI's own DNX enterprise tree; it is a self-contained vendor MIB. It was typically deployed on Eastern Research DNX digital cross-connect/multiplexer chassis providing multiple synchronous serial WAN circuits in telco or enterprise WAN aggregation environments. Engineers can download the ERI-DNX-OCTAL-HIGH-SPEED-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ERI-DNX-OCTAL-HIGH-SPEED-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

  • Eastern Research Inc. DNX multiplexer/digital cross-connect chassis

Monitoring Examples

A network technician would poll oHSConfigTable entries indexed by oHSCfgPortAddr, checking oHSCfgStatus and oHSCfgMode to confirm a given high-speed port is administratively up and running in the correct mode, and oHSCfgSpeed/oHSCfgType to verify the line speed and electrical interface type match the connected circuit. If a port shows an unexpected status, or its oHSCfgClock source doesn't match the intended master/slave clocking scheme, it would point to a misconfigured or failing synchronous serial link.

What Can Be Monitored

  • per-port administrative/operational status
  • port line speed and interface type
  • clocking source configuration
  • network loopback test mode
