Description: Manages Ethernet interface parameters, traffic counters, and port configuration on Net Insight Nimbra nodes.

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 NETI-ETH-MIB?

NETI-ETH-MIB is a vendor-specific SNMP module from Net Insight, used to manage Ethernet-like transport services and physical/logical interfaces on Nimbra media transport nodes. It exposes configuration and status data for Ethernet trail termination points (virtual interfaces), physical port settings, interface groups used for 1+1 protection, and forwarding function bindings between physical and logical interfaces. It is used heavily for monitoring hardware and software interface status, including port operational/administrative state, protection-switching status, and per-interface traffic load (transmit/receive utilization) as performance counters. The MIB references vendor-specific capability flags (e.g. performance monitoring and fault management support), indicating dependence on companion Net Insight Nimbra platform MIBs sharing the same device model. It is typically deployed in broadcast and media transport networks where Nimbra nodes carry Ethernet services over a DTM (Dynamic synchronous Transfer Mode) backbone, and a NETI-ETH-MIB download is typically the starting point for loading the module into an SNMP management platform.

IPNetwork Monitor allows you to monitor SNMP objects defined in NETI-ETH-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

  • Net Insight Nimbra media transport node
  • Ethernet transport/service gateway

Monitoring Examples

An administrator would poll ethDevIfgFirstIndex/ethDevIfgNextIndex to enumerate protection interface groups and check ethDevCapConfigurableFaultMgmt to confirm which fault-management features a device supports. Polling ethStatDcap1TxLoad and ethStatDcap1RxLoad on a given port reveals current transmit/receive load percentages, and a sustained spike near 100% would indicate link congestion or a misconfigured bandwidth allocation. The ethFwdCustomerId object lets an operator correlate forwarding function entries back to specific customer services for SLA verification.

What Can Be Monitored

  • Ethernet port admin/operational status
  • protection interface group state
  • transmit/receive load percentage
  • forwarding function customer mapping
  • fault management capability flags

How to Use in IPNetwork Monitor

Example using ethFwdRstpTopologyChangeCount OID:

Select a Net Insight Nimbra media transport node (Ethernet transport services) 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 ethFwdRstpTopologyChangeCount 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 total number of topology changes detected by this bridge since the management entity was last reset or initialized. 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.
