QOSTRAFFIC-MIB

Description: Manages Nortel Networks QoS traffic classification policies, DSCP marking rules, and traffic shaping configuration.

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.

QOSTRAFFIC-MIB is a Nortel Networks enterprise MIB, part of the Meridian/Succession Multimedia (SMP) Call Server product family, that reports zone-based QoS traffic statistics for VoIP/telephony traffic managed by the Call Server; its actual content is a per-zone traffic report table rather than DSCP marking/shaping configuration. It captures call volume, blocked calls, latency violations, packet loss, and jitter statistics for each configured network zone. This is a performance/quality monitoring MIB focused on voice call quality - ztCallsBlockedIn and ztInThrViol reveal capacity or threshold problems, while ztUnacpLatencyIn, ztUnacpPacketLossIn, and ztUnacpJitterIn directly measure whether voice quality has degraded below acceptable levels in a given zone, the telephony equivalent of a performance-health check. It's part of the Nortel Meridian/SMP Call Server MIB family and depends on that platform's zone-based network configuration model. It's deployed in enterprise Nortel Meridian/Succession telephony deployments to monitor voice quality across WAN-connected sites/zones. Engineers can download the QOSTRAFFIC-MIB file directly to load it into their MIB browser.

An admin polls ztZoneTable/ztZoneEntry to compare ztCallsMadeIn against ztCallsBlockedIn for a given zone, spotting call admission control blocking calls due to insufficient bandwidth. ztUnacpLatencyIn, ztUnacpPacketLossIn, and ztUnacpJitterIn are checked together to confirm whether a zone is experiencing unacceptable voice quality, and a spike in ztInThrViol (threshold violations) over ztIntervalIn flags a zone needing bandwidth or QoS remediation. ztPeakIn and ztAvgIn give call-volume trend context for capacity planning.

Vendor-private MIB for Quality of Service traffic management; manages QoS policies, traffic classification, and priority queuing.
