Description: NETGEAR-QOS-DIFFSERV-EXTENSIONS-MIB module

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 NETGEAR-QOS-DIFFSERV-EXTENSIONS-MIB?

NETGEAR-QOS-DIFFSERV-EXTENSIONS-MIB is a private Netgear FastPath MIB that extends standard DiffServ QoS configuration with auxiliary multi-field classifier objects, allowing traffic classification rules based on combinations of destination/source IP address, mask, protocol, and Layer 4 port ranges. It exposes a classifier table where each entry defines matching criteria used to bucket traffic into DiffServ classes for QoS treatment. This MIB is chiefly configuration-oriented rather than a live counter set, but it supports monitoring in the sense that an administrator can verify classifier rules are correctly provisioned to ensure the right traffic receives prioritized or restricted treatment, catching misclassification that could cause application performance problems. It is explicitly an extension of the IETF standard DiffServ MIB, adding multi-field classification beyond what the base DiffServ MIB provides. It is deployed on Netgear FastPath-based managed switches implementing QoS policies in enterprise networks. Engineers can download the NETGEAR-QOS-DIFFSERV-EXTENSIONS-MIB file directly to load it into their MIB browser.

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

  • Netgear FastPath-based managed switch

Monitoring Examples

An administrator would walk agentDiffServAuxMfClfrTable/agentDiffServAuxMfClfrEntry by agentDiffServAuxMfClfrId to verify agentDiffServAuxMfClfrDstAddr/agentDiffServAuxMfClfrDstMask and agentDiffServAuxMfClfrSrcL4PortMin/Max match the intended traffic-matching rule for a QoS policy, such as classifying VoIP or iSCSI traffic. An unexpected agentDiffServAuxMfClfrProtocol value or a missing classifier entry would explain why certain traffic isn't receiving its expected QoS treatment. agentDiffServAuxMfClfrNextFree is checked to confirm classifier table capacity before provisioning new rules.

What Can Be Monitored

  • multi-field classifier rules
  • source/destination IP and mask match criteria
  • protocol and L4 port range criteria
  • classifier table capacity/next free index
