Description: Manages Quanta Computer switch DiffServ private extensions for DSCP-to-queue mapping and per-class traffic handling.

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 QOS-DIFFSERV-PRIVATE-MIB?

QOS-DIFFSERV-PRIVATE-MIB is a Quanta Computer Inc. proprietary MIB (built on the shared FastPath-derived DiffServ object model) implementing DiffServ QoS classification and policy on Quanta switches. Its objects cover a global admin mode, class/class-rule/policy/policy-instance/policy-attribute/service table size and maximum counters, and a class table (index, name, type, ACL number, storage type, row status, ACL type, protocol type). As a configuration MIB it lets an administrator confirm which DiffServ classes and ACL-based rules are configured and remaining table capacity. It is deployed on Quanta Computer switches. Engineers can download the QOS-DIFFSERV-PRIVATE-MIB file directly to load it into their MIB browser.

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

  • Quanta Computer switches

Monitoring Examples

An administrator checks agentDiffServClassTable to confirm which DiffServ classes are currently configured on a Quanta Computer switch.

What Can Be Monitored

  • DiffServ class/policy configuration and capacity usage

How to Use in IPNetwork Monitor

Example using agentDiffServPolicyPerfInOfferedOctets OID:

Select a Quanta Computer switch (DiffServ QoS classification) 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 agentDiffServPolicyPerfInOfferedOctets 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 offered octets count for the inbound policy-class instance performance entry. 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.
