Description: Eastern Research Inc. DNX nest system administration MIB for chassis, slot, and system-level management of DNX-88/DNX-11.

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 ERI-DNX-NEST-SYS-MIB?

This is Eastern Research Inc.'s enterprise MIB for administering the "nest" chassis system of the DNX-88/DNX-11 multiplexer platforms, managing slot, device, and redundancy configuration. It exposes a slot configuration table capturing configured vs. actual device type per slot, device operational state, alarm level, device name/version, and redundancy role, plus objects for software upgrade and nest expansion administration. This is a clear hardware status monitoring MIB: an operator can check slotDeviceState and slotAlarmLevel per slotNbr to detect a failed or alarming card, compare slotConfigDeviceType against slotActualDeviceType to catch a mismatched/incorrectly inserted module, and track slotDeviceRedundancy to confirm redundant slot pairing is intact. No explicit dependency on other MIBs is indicated; it appears self-contained. It is typically deployed in Eastern Research DNX-88/DNX-11 telecom multiplexer chassis used in carrier/enterprise transport networks. Network engineers evaluating or troubleshooting this functionality can download the ERI-DNX-NEST-SYS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ERI-DNX-NEST-SYS-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-88/DNX-11 nest multiplexer chassis

Monitoring Examples

Polling slotConfigTable for slotDeviceState and slotAlarmLevel per slotNbr identifies a slot reporting a fault or alarm condition, while comparing slotConfigDeviceType to slotActualDeviceType reveals a mismatch, such as a technician inserting the wrong card type into a slot. slotDeviceVersion shows the installed card's software/firmware version, useful for confirming all nest modules are running a consistent, supported release before a maintenance window.

What Can Be Monitored

  • per-slot device operational state
  • per-slot alarm level
  • configured vs. actual device type mismatch
  • device firmware/software version
  • slot redundancy role

How to Use in IPNetwork Monitor

Example using slotMiscState OID:

Select an Eastern Research Inc. DNX-88/DNX-11 nest multiplexer chassis (slot/redundancy administration) 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 slotMiscState into the Find box to locate it in the OID tree, then select it and click OK. The current slot/device miscellaneous state conditions. none (0) no misc condition errors (1) errors reported on device test (2) device is in test mode errors-test (3) errors reported on device while in test mode clockSrc (4) device is the source for the. 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 an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is anything other than 'none', since that indicates the condition this object reports has changed to one worth investigating. Click Finish to create the monitor; you can adjust any parameter later.
