Description: Monitors Sonus Networks transport network resource utilization including bandwidth and bearer channel allocation.

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 SONUS-TRANSPORT-RESOURCES-MIB?

SONUS-TRANSPORT-RESOURCES-MIB is a vendor-specific MIB from Sonus Networks that monitors transport-layer network interface (NIF) resource utilization on its softswitch/media gateway platforms, including bandwidth and bearer-channel allocation. It exposes per-NIF state, active call and reserved-resource counts, and current/maximum/actual link speed along with speed deviation. Its monitoring value is centered on hardware/transport resource status: sonusNifStatState shows whether a transport interface is operational, and sonusNifStatSpeedDeviation flags a bearer path running slower than expected, both signs of transport-layer degradation that would affect voice quality or call admission. It also tracks packet network server (PNS) administration via sonusPnsAdmnTable, tying transport resources to the platform's overall resource-management framework. It is deployed on Sonus media gateways in carrier VoIP networks where bearer transport capacity must be tracked to avoid call blocking. Engineers can download the SONUS-TRANSPORT-RESOURCES-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SONUS-TRANSPORT-RESOURCES-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.

Sonus Networks media gateway/softswitch

Monitoring Examples

A capacity planner would poll sonusNifStatTable/sonusNifStatEntry, checking sonusNifStatCallNum against sonusNifStatResNum to see how close a network interface is to its reserved resource limit, and sonusNifStatState to confirm the interface is up. sonusNifStatSpeedCur versus sonusNifStatSpeedMax and sonusNifStatSpeedActual would be compared to detect a link running below its provisioned speed, with sonusNifStatSpeedDeviation quantifying the gap. sonusPnsAdmnTable would be reviewed for administrative state of the packet network server resources feeding these interfaces.

How to Use in IPNetwork Monitor

Example using sonusNifStatState OID:

Select a Sonus Networks media gateway/softswitch (transport interface/bandwidth resource status) 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 sonusNifStatState 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 state of this NIF. 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 'inService', 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.
