Description: Defines Sonus Networks softswitch common objects, enterprise OID root, and shared platform parameters.

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-COMMON-MIB?

SONUS-COMMON-MIB is a common platform MIB from Sonus Networks (a VoIP/softswitch and session border controller vendor, later part of Ribbon Communications) that defines shared management objects and the enterprise OID root used across all Sonus device families. Unlike many "common" registration MIBs, it does expose live configuration/status data, specifically a network-management client table that tracks the SNMP management stations authorized to interact with a Sonus device. Through this table, operators can monitor which management clients are configured, their operational state, IP address, access level (read/write), and per-client SNMP community strings and trap-delivery state -- useful for auditing and troubleshooting who can manage or receive alerts from the softswitch. Its main dependency is on standard SNMPv2-SMI conventions for indexing and community-based security, and it forms the common base that Sonus's call-signaling, media, and trunk-group MIBs build upon. It is deployed across Sonus/Ribbon softswitch and session border controller platforms in carrier and enterprise VoIP networks. Loading SONUS-COMMON-MIB into a MIB Browser lets an administrator inspect the sonusNetMgmtClientTable structure directly, confirming which management stations and access levels are defined before relying on it in a live softswitch deployment.

IPNetwork Monitor allows you to monitor SNMP objects defined in SONUS-COMMON-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 / Ribbon Communications softswitch and SBC platforms, entire device family (SNMP management-client table)

Monitoring Examples

An admin can poll sonusNetMgmtClientTable/sonusNetMgmtClientEntry to see each configured NMS client's sonusNetMgmtClientName, sonusNetMgmtClientState, and sonusNetMgmtClientIpAddr, confirming whether a management station is active and reachable. Checking sonusNetMgmtClientAccess alongside sonusNetMgmtClientSnmpCommunityGet/Set reveals whether a client has read-only or read-write access and which community strings it uses -- useful when auditing SNMP security on a softswitch. sonusNetMgmtClientTrapState shows whether trap delivery to that client is enabled, so an admin can diagnose why alerts from the Sonus platform aren't reaching a particular NMS.

What Can Be Monitored

configured SNMP management clients
management client operational state
management client IP address
SNMP access level (read/write)
SNMP community strings per client
trap delivery state per client

How to Use in IPNetwork Monitor

Example using sonusNetMgmtInformReqDiscards OID:

Select a Sonus Networks / Ribbon Communications softswitch or SBC platform 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 sonusNetMgmtInformReqDiscards into the Find box to locate it in the OID tree, then select it and click OK. It reports the number of InformRequest notification PDUs that were discarded for a management client. 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 Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since discarded InformRequests mean notifications aren't reliably reaching that management client. Click Finish to create the monitor; you can adjust any parameter later.

When the maximum number has been reached, consectutive InformRequest PDUs will be discarded (i.e. not sent.) Increasing this number will increase the memory consumed by the GSX software and the CPU time required to process the InformRequest PDUs. This MIB object does not apply to SNMPv1 or SNMPv2 Trap PDUs.
NTF sonusNetMgmtClientInformReqQueueFlushedNotification	1.3.6.1.4.1.2879.2.1.5.2.0.1			The specified number of InformRequest PDUs destined to the specified Management Client were flushed from the InformRequest PDU queue because no Response PDUs were were received from the Management Client. This situtation could occur if the Management Client cannot quickly process and respond to InformRequest PDUs that it receives, or if communications is lost with the Management Client. If this situation occurs occasionally, it is recommended to increase the InformRequest PDU timeout and/or retry values (see sonusNetMgmtClientInformReqTimeout and sonusNetMgmtClientInformReqRetries.) If this situation occurs repeatedly, it is an indication that communications is lost with the Management Client, either because of network problems, or because the Management Client is no longer operational. It is recommended that this device be configured to send a Trap PDU, not an InformRequest PDU, for this Notification to all Management Clients, thus bypassing a problematic InformRequest PDU queue and allowing the situation to be quickly identified and resolved.
NTF sonusNetMgmtClientInformReqQueueFullNotification	1.3.6.1.4.1.2879.2.1.5.2.0.2			The specified number of InformRequest PDUs destined to the specified Management Client were discard because its InformRequest PDU queue was full. This situtation could occur if the Management Client cannot quickly process and respond to InformRequest PDUs that it receives, or if communications is lost with the Management Client. If this situation occurs occasionally, it is recommended to increase the InformRequest PDU queue size (see sonusNetMgmtClientInformReqMaxQueue.) If this situation occurs repeatedly, it is an indication that communications is lost with the Management Client, either because of network problems, or because the Management Client is no longer operational. It is recommended that this device be configured to send a Trap PDU, not an InformRequest PDU, for this Notification to all Management Clients, thus bypassing a problematic InformRequest PDU queue and allowing the situation to be quickly identified and resolved.
