Description: Manages Cisco WAN SRCP (Simple Resource Coordination Protocol) for media gateway resource control.

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 CISCO-WAN-SRCP-MIB?

CISCO-WAN-SRCP-MIB manages SRCP (Simple Resource Coordination Protocol) implementations used between a Media Gateway Controller (MGC, acting as SRCP client) and a Media Gateway (MG, acting as SRCP server) on Cisco WAN voice platforms. It exposes protocol version and port configuration along with a peer table tracking each SRCP peer's name, port, heartbeat interval, and time since last heartbeat. Its central monitoring value is software/protocol liveness: srcpPeerTimeSinceHeartbeat rising toward or past srcpPeerHeartbeatInterval indicates a peer MGC or MG has stopped responding, signaling a control-plane failure between the gateway controller and gateway that would disrupt call setup/teardown even if the underlying hardware is otherwise healthy. It explicitly references CISCO-WAN-MG-MIB (abbreviated MGMIB) as a related module for gateway-side objects. It is deployed in Cisco MGX-based media gateway networks using SRCP for controller-to-gateway resource coordination, and administrators often load the module into a CISCO-WAN-SRCP-MIB MIB Browser to inspect peer heartbeat values interactively before scripting automated polling.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WAN-SRCP-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

  • Cisco WAN media gateways and media gateway controllers (MGX-based)

Monitoring Examples

An operator would poll srcpPeerTable by srcpPeerId to check srcpPeerTimeSinceHeartbeat against the configured srcpPeerHeartbeatInterval for each peer, flagging any peer where elapsed time exceeds the interval as a lost heartbeat/control-plane outage. srcpPeerMaxPduSize helps verify protocol negotiation parameters match between the MGC and MG, while srcpVersion confirms both ends are running compatible SRCP protocol versions.

What Can Be Monitored

  • peer heartbeat interval and elapsed time since last heartbeat
  • SRCP protocol version
  • peer port configuration
  • maximum PDU size negotiation

How to Use in IPNetwork Monitor

Example using srcpPeerGrpTimeSinceHeartbeat OID:

Select a Cisco WAN media gateway or media gateway controller (MGX-based) 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 srcpPeerGrpTimeSinceHeartbeat 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. It reports, in milliseconds, how long it has been since the last SRCP heartbeat was received from the peer media gateway controller. 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 this value exceeds 30,000 (30 seconds), which would indicate the peer has stopped sending heartbeats and may have failed. Click Finish to create the monitor; you can adjust any parameter later.
