hm2AgentCosQueueMgmtWredDropProbability
Module: HM2-PLATFORM-QOS-COS-MIB
OID (symbolic): HM2-PLATFORM-QOS-COS-MIB::hm2AgentCosQueueMgmtWredDropProbability
OID (numeric): 1.3.6.1.4.1.248.12.3.3.2.5.1.9
Node type: OBJECT-TYPE
Type: Percent
Access: read-write
Description: A scaling factor used for the WRED calculation to determine the packet drop probability for the current drop precedence level. Packet dropping begins when hm2AgentCosQueueMgmtWredMinThreshold is reached and proceeds linearly up to the percentage value specified by this object until the hm2AgentCosQueueMgmtWredMaxThreshold is reached, beyond which all packets are dropped.
The default value is 10.
This object is only used when hm2AgentCosQueueMgmtType is set to wred(2).
What is hm2AgentCosQueueMgmtWredDropProbability?
The maximum WRED packet drop probability (as a percentage, default 10) reached once the queue hits its WRED max threshold; drop probability ramps up linearly from zero starting at the WRED min threshold. Only applies when hm2AgentCosQueueMgmtType is set to wred — raise it to drop more aggressively under sustained congestion, or lower it to be more tolerant of bursts.
