Description: Manages Sonus Networks softswitch IP protocol stack parameters, QoS marking, and transport settings.

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-IP-PROTOCOL-MIB?

SONUS-IP-PROTOCOL-MIB is a vendor-specific MIB from Sonus Networks that mirrors the standard IP-MIB to expose the IP/ICMP protocol stack statistics of its softswitch platforms. It covers IP forwarding mode, default TTL, and counters for received, forwarded, discarded, and delivered datagrams, plus header and address errors. Its monitoring value is squarely software/network-stack health: rising sonusIpInHdrErrors, sonusIpInAddrErrors, or sonusIpInDiscards indicate malformed traffic or a misconfigured network path reaching the device, while sonusIpInDelivers versus sonusIpInReceives shows how much inbound traffic is actually being processed locally versus dropped. It closely parallels the standard IETF IP-MIB/ICMP-MIB object semantics, reimplemented under the Sonus enterprise tree (sonusIp, sonusIcmp) for platform-specific reporting. It is deployed on Sonus softswitches and media gateways as a general network-health diagnostic alongside the call-signaling MIBs. Engineers can download the SONUS-IP-PROTOCOL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SONUS-IP-PROTOCOL-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

  • Sonus Networks softswitch/media gateway

Monitoring Examples

A network engineer would poll sonusIpInReceives, sonusIpInDelivers, and sonusIpForwDatagrams together to understand traffic volume flowing through and being forwarded by the device, and would watch sonusIpInDiscards and sonusIpInUnknownProtos for signs of traffic being dropped due to congestion or unsupported protocols. sonusIpInHdrErrors and sonusIpInAddrErrors climbing steadily would point to a misbehaving upstream device sending malformed IP packets. sonusIpDefaultTTL and sonusIpForwarding confirm the box's basic IP configuration matches expectations.

What Can Be Monitored

  • IP datagrams received/delivered/forwarded
  • header and address errors
  • discarded and unknown-protocol packets
  • default TTL
  • IP forwarding mode

How to Use in IPNetwork Monitor

Example using sonusIpInReceives OID:

Select a Sonus Networks softswitch/media gateway (IP/ICMP protocol-stack statistics) 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 sonusIpInReceives 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 input datagrams received from interfaces, including those received in error. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
