Description: Marvell Semiconductor Weighted Random Tail Drop (WRTD) MIB providing queue congestion management and QoS drop policy objects.
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 MARVELL-WeightedRandomTailDrop-MIB?
MARVELL-WeightedRandomTailDrop-MIB is a Marvell Semiconductor proprietary module exposing configuration and status for the Weighted Random Tail Drop (WRTD) queue congestion-management mechanism used in QoS traffic management on Marvell switch silicon. It provides objects reflecting the current WRTD feature status and its status following a device reset, indicating whether the congestion-avoidance drop policy is active. Its monitoring value is centered on QoS/software configuration status: operators can verify whether WRTD is currently enabled and whether that setting persisted correctly across a reset, which affects how the switch handles queue congestion and packet drops under load. As a narrowly scoped feature MIB, it is used alongside broader Marvell QoS and queue-management MIBs for complete traffic-management visibility. It is typically deployed on Marvell-chipset-based switches in environments sensitive to congestion behavior, such as data center or service-provider aggregation switches. Engineers can download the MARVELL-WeightedRandomTailDrop-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in MARVELL-WeightedRandomTailDrop-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
- Marvell-chipset-based switches
Monitoring Examples
An operator would poll rlWeightedRandomTailDropCurrentStatus to confirm whether WRTD congestion management is currently active, and compare it with rlWeightedRandomTailDropStatusAfterReset to see the expected post-reboot state. A mismatch between the two values would reveal that the WRTD configuration was not applied or persisted correctly after the last device reset, potentially causing unexpected tail-drop behavior under congestion.
What Can Be Monitored
- current WRTD feature status
- WRTD status after reset
