Description: Provides management objects for managing H.320 ISDN-based videoconference dial control on Cisco multimedia routers and gateways.

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-H320-DIAL-CONTROL-MIB?

CISCO-H320-DIAL-CONTROL-MIB is a Cisco MIB that extends the IETF Dial Control MIB (RFC 2128) to provide ITU-T H.320 videoconferencing call information over ISDN on Cisco multimedia routers and gateways. It exposes call history data for H.320 video calls, including call type, bandwidth used, and per-call transmit/receive video codec and packet/byte counts. This MIB is used to monitor the operational performance of videoconferencing calls, letting an administrator review cvH320CallHistoryUsedBandwidth and cvH320CallHistoryTxVideoCodec/RxVideoCodec to confirm calls negotiated the expected codec and bandwidth, and inspect packet/byte counters to detect degraded call quality or dropped video. It explicitly depends on and enhances the IETF Dial Control MIB (RFC 2128) for the underlying call/connection framework. It is typically deployed on Cisco ISDN-based videoconferencing gateways or multimedia routers bridging H.320 endpoints over narrowband ISDN telephony networks. Network engineers evaluating or troubleshooting this functionality can download the CISCO-H320-DIAL-CONTROL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-H320-DIAL-CONTROL-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.

Monitoring Examples

An administrator would poll cvH320CallHistoryTable/cvH320CallHistoryEntry keyed by cvH320CallHistoryConnectionId to review each completed call's cvH320CallHistoryH320CallType and cvH320CallHistoryUsedBandwidth, confirming the call used the negotiated bandwidth class. Comparing cvH320CallHistoryTxVideoPackets/TxVideoBytes against cvH320CallHistoryRxVideoPackets/RxVideoBytes for a given cvH320CallHistoryIncomingConnectionId would reveal an asymmetric or low-throughput call indicative of a poor ISDN line or codec negotiation problem.

What Can Be Monitored

H.320 call type
bandwidth used per call
transmit/receive video codec
transmit/receive video packet and byte counts
call connection history
