What Is CISCO-MEDIA-GATEWAY-MIB?

CISCO-MEDIA-GATEWAY-MIB is a Cisco Systems MIB module for managing Trunk Media Gateways, the Cisco media gateway network elements that convert audio between PSTN telephone circuits and Voice-over-IP/ATM packet networks, interfacing to Class 4/5 PSTN switches on one side and a VoIP/ATM network on the other. It exposes call-control and gateway-configuration data: per-gateway table entries with domain name and physical index, administrative and service (operational) state, IP-related configuration, and feature toggles such as source filtering, lawful-intercept enablement, and V.23 signaling support. Its monitoring emphasis is on software/operational status of the gateway function - checking cmgwServiceState against cmgwAdminState reveals whether a gateway is actually in service versus administratively down or transitioning, and cmgwGraceTime shows whether a graceful shutdown/reload is in progress, all key indicators of call-handling availability. It depends on Cisco's broader VoIP/media-gateway control architecture and typically works alongside signaling/call-control MIBs (e.g., MGCP- or H.248/Megaco-related MIBs) for complete call-path visibility. It is deployed on Cisco trunk media gateway platforms in service-provider and enterprise VoIP interconnection networks.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MEDIA-GATEWAY-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.

What Can Be Monitored

  • gateway administrative vs. service state
  • graceful shutdown/reload timer
  • lawful intercept enablement
  • source filtering status
  • V.23 signaling support status
  • gateway domain/IP configuration

Supported Devices

  • Cisco Trunk Media Gateway platforms (VoIP/PSTN interconnection)

Monitoring Examples

An operator would poll cMediaGwTable/cMediaGwEntry, keying on cmgwIndex, to compare cmgwAdminState against cmgwServiceState for each gateway and detect one that has failed to come into service after being administratively enabled. cmgwGraceTime would be checked to see if a gateway is mid-way through a graceful drain, while cmgwLawInterceptEnabled and cmgwV23Enabled reveal whether specific compliance or legacy-signaling features are turned on for that gateway's domain (cmgwDomainName).

OIDs
OID symbolicOID numericTypeAccessDescription
ciscoMediaGatewayMIB1.3.6.1.4.1.9.9.324The MIB module for managing Trunk Media Gateway. A Media Gateway is a network element that provides conversion between the audio signals carried on telephone circuits and data packets carried over the Internet or over other packet data networks. Trunk Media Gateway interface is between the telephone network and a Voice over IP/ATM network. The interface on a Trunk Gateway terminates a trunk connected to PSTN switch (e.g., Class 5, Class 4, etc.). Media Gateways use a call control architecture where the call control 'intelligence' is outside the gateways and handled by external call control elements, called Media Gateway Controllers (MGCs). The MGCs or Call Agents, synchronize with each other to send coherent commands to the gateways under their control. MGCs use master/slave protocols to command the gateways under their control. Examples of these protocols are: * Simple Gateway Control Protocol * Media Gateway Control Protocol * Megaco (H.248) * Simple Resource Control Protocol To connect MG to MGCs using these control protocols through an IP/UDP Ports which must be configured. To resolve IP Addresses, DNS name services may be used.

For example cmgwSignalProtocol is 'h248(3)' and this object can be string '1' or '1.0', '2' or '2.0'. 'MAX' is a special string indicating the gateway will use the highest protocol version supported in the gateway, but it can be changed to lower version after it negotiates with MGC. The final negotiated protocol version will be indicated in cmgwSignalProtocolVersion. The version strings other than 'MAX' can be specified for the gateway to communicate with the MGC which doesn't support service capabilities negotiation. For example if a MGC supports only version 1.0 MGCP, this object should be set to '1' to instruct the gateway using MGCP version 1.0 format messages to communicate with MGC.

A cluster is a group of endpoints that share a particular bearer possibility for connections among each other. disabled(1) - The generation of the cluster attribute is disabled. enabled(2) - Unconditionally generate the cluster attribute. conditionalEnabled(3) - The generation of the cluster attribute is upon MGC request.
INT cMediaGwCcCfgDefBearerTraffic1.3.6.1.4.1.9.9.324.1.1.7.1.17INTEGERread-writeThis object specifies the combination of the network type (IP/ATM), virtual circuit type (PVC/SVC) and ATM adaptation layer type (AAL1/AAL2/AAL5) for the connection used in transporting bearer traffic. ipPvcAal5 (1) - The bearer traffic is transported in IP network, through Permanent Virtual Circuit(PVC) over AAL5 adaptation layer. atmPvcAal2 (2) - The bearer traffic is transported in ATM network, through Permanent Virtual Circuit(PVC) over AAL2 adaptation layer. atmSvcAal2 (3) - The bearer traffic is transported in ATM network, through Switching Virtual Circuit(SVC) over AAL2 adaptation layer. atmSvcAal1 (4) - The bearer traffic is transported in ATM network, through Switching Virtual Circuit(SVC) over AAL1 adaptation layer. In MGCP, if the call agent specifies the bear traffic type in the local connection options (CRCX request), configuration of this object will have no effect, otherwise the value of this object will be used when media gateway sending CRCX response.
STR cMediaGwCcCfgDefRtpNamePrefix1.3.6.1.4.1.9.9.324.1.1.7.1.18SnmpAdminStringread-writeThis object specifies the prefix of the name schema for default RTP terminations.
