Description: An extension to the Eltex MES interfaces MIB that adds per-interface configuration and statistics objects on MES platforms.

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 ELTEX-MES-eltInterfaces?

This Eltex private enterprise MIB extends interface management on Eltex MES switches beyond the standard IF-MIB, adding switch-media-specific configuration and real-time utilization statistics per physical interface. It exposes an interface configuration table including SFP transceiver operating mode, plus a separate utilization table tracking current inbound/outbound packet counts and rates averaged over a configurable time window for each interface. Its monitoring value is direct performance and hardware status tracking at the port level: administrators can watch real-time traffic rates and packet counts per port to spot congestion or a link running far above/below expected utilization, and check SFP operation mode to confirm optical transceiver configuration matches the installed module. It explicitly builds on and extends the standard IF-MIB (ifTable/ifIndex model), referencing ifIndex-style indexing for its own tables. It is deployed on Eltex MES switches wherever granular per-port traffic utilization and SFP status monitoring beyond basic IF-MIB counters is needed. Engineers can download the ELTEX-MES-eltInterfaces file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ELTEX-MES-eltInterfaces. 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

Eltex MES Ethernet switch

Monitoring Examples

An admin walks eltSwIfTable/eltSwIfEntry by eltSwIfIndex to check eltSwIfSfpOperationMode, confirming an installed SFP module is running in the expected mode (e.g., auto-negotiation vs. forced speed). Polling eltSwIfUtilizationTable/eltSwIfUtilizationEntry for eltSwIfUtilizationCurrentInRate and eltSwIfUtilizationCurrentOutRate over the eltSwIfUtilizationAverageTime window reveals a port approaching link saturation, while eltSwIfUtilizationCurrentInPkts/CurrentOutPkts show packet-level throughput.

What Can Be Monitored

SFP transceiver operation mode
current inbound/outbound packet rate
current inbound/outbound packet count
utilization averaging interval

How to Use in IPNetwork Monitor

Example using eltSwIfUtilizationCurrentInPkts OID:

Select an Eltex MES Ethernet switch (SFP mode/per-port utilization) 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 eltSwIfUtilizationCurrentInPkts 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 all (UC, MC and BC) packets received on the interface during last 5 seconds. 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.
