What Is CISCO-XGCP-MIB?
CISCO-XGCP-MIB manages Cisco's xGCP (a superset covering SGCP and MGCP) media gateway control protocol configuration and statistics, used where a call agent/Media Gateway Controller (MGC) coordinates a set of media gateways converting between circuit and packet voice/ATM signals in VoIP/VoATM deployments. It exposes configuration for call agent (MGC) group membership and addressing, plus per-media-gateway protocol behavior such as request timeouts, retry counts, and retry methods. Monitoring it centers on the health of the call-control relationship: the MGC configuration table reveals which MGC addresses and UDP ports a gateway is configured to register with, while the media gateway table's request timeout/retry settings and counts help diagnose signaling instability between gateway and controller, excessive retries suggest network or MGC-side problems. It depends on the underlying xGCP/MGCP/SGCP protocol family it manages and complements Cisco's voice gateway hardware MIBs. It is deployed on Cisco voice gateways and media gateway controllers in VoIP/VoATM telephony networks. Engineers can download the CISCO-XGCP-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-XGCP-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 VoIP/VoATM media gateway
- Media Gateway Controller (MGC)/call agent
Monitoring Examples
Polling cXgcpMgcConfigTable/cXgcpMgcConfigEntry, keyed by cXgcpMgcConfigMgcGrpNum, shows the configured cXgcpMgcConfigAddress and cXgcpMgcConfigGatewayUdpPort a gateway uses to reach its call agent; an address mismatch would explain a gateway failing to register with its MGC. cXgcpMediaGwTable/cXgcpMediaGwEntry exposes cXgcpMediaGwRequestTimeOut and cXgcpMediaGwRequestRetries, where rising retry counts against a normally stable baseline indicate degraded signaling connectivity to the call agent. cXgcpNotifications would trap the operator when such failures occur.
What Can Be Monitored
- MGC address/port configuration
- gateway registration status
- request timeout and retry settings
- retry method/count anomalies

How to Use in IPNetwork Monitor
Example using cXgcpMsgStatsSuccessMessages OID:
Select a Cisco VoIP/VoATM media gateway / Media Gateway Controller (MGC) 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 cXgcpMsgStatsSuccessMessages 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. This object indicates the number of successful messages that communicate with the MGC on that IP address. 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 sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

| ciscoXgcpMIB | 1.3.6.1.4.1.9.9.318 | This MIB is an enhancement for existing XGCP-MIB. xGCP is a set of protocols, for example SGCP (Simple Gateway Control Protocol) and MGCP (Media Gateway Control Protocol), which are designed as a control protocol within a distributed system that appears to the outside as a single VoIP/VoATM gateway. This system is composed of a call agent (or MGC, Media Gateway Controller) and of a set of 'media gateways' that perform the conversion of media signals between circuits and packets. In the xGCP model, the gateways focus on the audio signal translation function, while the call agent handles the signaling and call processing functions. Examples of Gateway Control Protocols are: * Simple Gateway Control Protocol (SGCP) * Media Gateway Control Protocol (MGCP) xGCP assumes a connection model where the basic constructs are: Endpoints : sources or sinks of data that could be physical or virtual. Connections : an association between two or more endpoints with the purpose of transmitting data between these endpoints. Once this association is established for both endpoints, data transfer between these endpoints can take place. Connections are grouped in calls. One or more connections can belong to one call. Connections and calls are set up at the initiative of one or several call agents. Terminologies used: AAL : ATM Adaptation Layer AUCX : Audit Connection Command used by the MGC to find out the status of a given gateway connection. AUEP : Audit Endpoint Command used by the MGC to find out the status of a given endpoint. CCAPI : Call Control Application Program Interface. CID : Channel Identifier CRCX : Connection Command from a MGC to request the gateway MG : Media Gateway MGC : Media Gateway Controller DLCX : Delete Command. This command can be initiated by either the MGC or gateway. GSM : Global System for Mobile Communications GW : Gateway. HP : Hairpin MDCX : Modify Connection Command from a MGC to request the gateway NSE : Negative Stuffing Event NTFY : A Notify Command sent from a gateway to a MGC in response to a RQNT command. PSTN : Public Switched Telephone Network RQNT : Request To Nofity Command from a MGC to request the gateway to provide a notification for configuration changes. RSIP : Restart in Progress Command. This command can be initiated by either the MGC or gateway. SPRT : Simple Packet Relay Transport SSE : Silicon Switching Engine TDM : Time Division Multiplexing TGW : Target Gateway TWC : Three Way Calling VCCI : Virtual Circuit Connection Identifier VMG : Virtual Media Gateway. It is a logical representation of a module (or a set of modules) that has MG functionality. There could be multiple VMGs in a device. VoAAL2 : Voice over AAL2 | ||

The value of this object refers to the object cMgcGrpIndex from MGC Redundant Group Table, cMgcGrpParamTable. There are two conditions to associate a MGC group: 1. At least one MGC is associated with the MGC group 2. At least one protocol is associated with the MGC group If the value of the object is non-zero, it means the media gateway has a MGC Redundant Group. In the call setup, the parameters of call agents within the MGC Redundant Group will be sequentially tried according to its preference. This object cXgcpMgcConfigMgcGrpNum and object cXgcpMgcConfigAddress are mutually exclusive. The object cXgcpMgcConfigAddress can be set only when the object cXgcpMgcConfigMgcGrpNum is equal to 0. If the value of the object is 0, which means there is no MGC Redundant Group associated with the media gateway. It has only one call agent (in media gateway level) to communicate with.

The value of this object is the same as the value of object cMediaGwProtocolIndex from protocol table (cMediaGwProtocolTable). If the value of cXgcpMgcConfigMgcGrpNum is non-zero, this object will be ignored because the protocol will be determined by the MGC group. The initial value is 1, means the system should have at least one default protocol between the gateway and the MGC created in the cMeidaGwProtocolTable when the system is initialized. |
