Category: Quality of Service, Vendor: 3Com

Description: Manages Quality of Service configuration on 3Com SuperStack switching systems, including priority queue assignments and traffic class mappings.

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 A3COM-SWITCHING-SYSTEMS-QOS-MIB?

A3COM-SWITCHING-SYSTEMS-QOS-MIB is a 3Com private-enterprise MIB that manages Quality of Service configuration on 3Com SuperStack switching systems, covering generic traffic classification and flow-based classification for priority queueing. It exposes configuration data such as class definitions, class names, and flow-classification rules keyed on IP protocol type and source address, placing it in the configuration category rather than raw hardware sensor data. Its monitoring value lies mainly in the software/configuration domain: verifying that QoS classes and flow classifiers are correctly provisioned so traffic is prioritized as intended, and detecting classification errors that could cause traffic to be mis-queued. As a vendor-specific QoS module it is part of the broader 3Com switching-systems MIB tree and would typically be used alongside standard interface and traffic-statistics MIBs for full visibility. It is typically deployed on 3Com SuperStack switches in enterprise LANs that need class-based traffic prioritization. Engineers can download the A3COM-SWITCHING-SYSTEMS-QOS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-SWITCHING-SYSTEMS-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

  • 3Com SuperStack switch

Monitoring Examples

An administrator would inspect the a3ComQosGenClassTable (keyed by a3ComQosGenClassIndex) to confirm generic QoS class definitions like a3ComQosGenClassName and a3ComQosGenClassControlId are correctly provisioned, and check the a3ComQosFlowClassTable for flow-specific classification entries such as a3ComQosFlowClassIpProtoType and a3ComQosFlowClassSrcAddr. An unexpected or missing entry in either table would reveal a misconfigured QoS policy causing traffic from a given source or protocol to not receive its intended priority treatment.

What Can Be Monitored

  • QoS class definitions
  • flow classification rules
  • traffic priority/class mappings
  • protocol-based classification filters
