Description: MIB for PictureTel VCS H.323 IP videoconferencing statistics covering call bandwidth, logical channel, video encoder/decoder, and audio metrics

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 PICTURETEL-VCS-H323-MIB?

This is a PictureTel (an early videoconferencing vendor later merged into Polycom) private MIB for its VCS H.323 videoconferencing endpoints, covering call setup and per-channel media statistics for H.323-based IP video calls. It exposes call-level configuration (bandwidth, restriction flags), encoder/decoder counts, and per-channel statistics for video, audio, and T.120 data-collaboration streams exchanged with the far-end endpoint. Its monitoring value is software/call-quality status: ptH323CallBandwidth and ptH323CallRestricted reveal the negotiated call parameters, while the per-channel transmit/receive counters for video and audio let an admin detect asymmetric or degraded media flow (e.g., video transmitting but not receiving, indicating a one-way video fault) during a live call. It implements the ITU-T H.323 call model rather than depending on other IETF MIBs directly. It's typically deployed in enterprise videoconferencing bridge/endpoint monitoring for call-quality troubleshooting. Engineers can download the PICTURETEL-VCS-H323-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PICTURETEL-VCS-H323-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

PictureTel (Polycom) VCS H.323 videoconferencing endpoint/bridge

Monitoring Examples

An admin would poll ptH323ChannelStatTable, indexed by ptH323ChannelStatIndex, comparing ptH323ChannelVideoTransmitToFarEnd against ptH323ChannelVideoReceiveFromFarEnd to detect a one-way video failure on an active call. ptH323CallBandwidth confirms the call negotiated the expected bandwidth tier, and ptH323VideoNumberOfEncoders shows how many encoder resources are in use, useful when diagnosing capacity limits on a busy VCS bridge. ptH323ChannelTransmitT120Data and ptH323ChannelReceiveT120Data would reveal whether a data-collaboration (whiteboard/file-share) session alongside the video call is exchanging data correctly.

What Can Be Monitored

negotiated call bandwidth
call restriction flag
video transmit/receive byte counts
audio transmit/receive byte counts

How to Use in IPNetwork Monitor

Example using ptH323AudioTransmitActualBitRate OID:

Select a PictureTel (Polycom) VCS H.323 videoconferencing endpoint/bridge 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 ptH323AudioTransmitActualBitRate into the Find box to locate it in the OID tree, then select it and click OK. It reports the actual transmit bit rate (bits/sec). 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 Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the value drifts significantly from its normal baseline, since an unexpected change often points to a real underlying issue. Click Finish to create the monitor; you can adjust any parameter later.
