Description: Manages Quality of Service (QoS) settings on AudioCodes devices, including DSCP marking, traffic shaping, and prioritization for voice media and signaling traffic.

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 AC-QOS-MIB?

AC-QOS-MIB is an AudioCodes proprietary MIB covering Quality of Service configuration on AudioCodes VoIP gateways, session border controllers, and media gateways. It exposes configuration-oriented data such as DSCP marking policies, traffic shaping parameters, and prioritization rules applied to voice media (RTP) and signaling (SIP/H.323) traffic streams. While primarily a configuration MIB, it supports monitoring of the device's QoS enforcement status, letting administrators verify that voice traffic is receiving its intended priority and that shaping/marking settings are being applied correctly, which is important for detecting call-quality degradation caused by misconfigured QoS. As an AudioCodes-specific extension it works alongside standard networking concepts (e.g. IF-MIB, DiffServ marking) though it does not require them for basic use. It is typically deployed in enterprise or carrier VoIP networks where AudioCodes equipment handles PSTN gateway or SBC functions and QoS must be tuned to protect real-time voice traffic, and administrators can get an AC-QOS-MIB download to load these QoS objects into their SNMP management tool.

IPNetwork Monitor allows you to monitor SNMP objects defined in AC-QOS-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

AudioCodes VoIP gateway
AudioCodes Session Border Controller (SBC)

Monitoring Examples

No sample object names were provided for this MIB, so specific table/object names cannot be confirmed; in practice such a MIB would be expected to expose objects for per-class DSCP values and shaping rates that an administrator polls to confirm signaling and media queues are correctly marked. An anomaly such as an unexpected DSCP value or a shaping rate reverting to a default could explain voice-quality complaints like jitter or dropped calls. Because no sample_objects were supplied, this description is necessarily general rather than citing exact object names.

What Can Be Monitored

DSCP marking configuration
traffic shaping parameters
voice media traffic priority
signaling traffic priority

How to Use in IPNetwork Monitor

Example using acQoSQueueStatsPacketSent OID:

Select an AudioCodes Mediant-series gateway/SBC 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 acQoSQueueStatsPacketSent 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 the number of packets sent. AC INI-Param: N/A. 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.
