CISCOSB-WeightedRandomTailDrop-MIB

Description: Configures Weighted Random Early/Tail Drop (WRED/WRTD) QoS queuing on Cisco Small Business devices.

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.

CISCOSB-WeightedRandomTailDrop-MIB is a small Cisco Small Business private MIB that reports the operational status of the switch's Weighted Random/Tail Drop (WRED/WRTD) congestion-avoidance QoS feature, which selectively drops lower-priority packets from queues as they approach capacity to avoid global TCP synchronization. It exposes only a current status object and a status-after-reset object, making it a minimal feature-status MIB rather than a broad configuration or data-rich module. Its monitoring relevance is software/feature-state status: it lets an administrator confirm whether WRED/tail-drop congestion control is currently active on the device and what state it will resume in after a reboot, which affects how the switch behaves under queue congestion. It has no notable dependency on other MIBs beyond the shared CISCOSB private-enterprise structure. It is used on small-business switches where QoS queue-congestion behavior needs to be verified as part of broader traffic-management troubleshooting. Network engineers evaluating or troubleshooting this functionality can download the CISCOSB-WeightedRandomTailDrop-MIB file directly to load it into their MIB browser.

An administrator would poll rlWeightedRandomTailDropCurrentStatus to confirm whether WRED/WRTD is presently enabled or disabled on the switch, and check rlWeightedRandomTailDropStatusAfterReset to see what state it will revert to on the next reboot. If queue congestion symptoms (excessive drops or bursty latency) appear, confirming rlWeightedRandomTailDropCurrentStatus is set as expected is a quick first check. Because the MIB exposes only these two status objects, it offers coarse on/off visibility rather than per-queue statistics.
