agentCosQueueWredDecayExponent
Module: FASTPATH-QOS-COS-MIB
OID (symbolic): FASTPATH-QOS-COS-MIB::agentCosQueueWredDecayExponent
OID (numeric): 1.3.6.1.4.1.674.10895.5000.2.6132.1.1.3.3.2.3.1.4
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The decay exponent value used with the weighted random early discard (WRED) algorithm to determine how quickly the average queue length calculation reacts to the current length of the queue. A higher value produces a slower response, meaning previously sampled queue length values are factored into the calculation for a longer period of time. The default value is 9.
Use caution when changing this value from its default. If set too low, short traffic bursts can cause WRED to drop too many packets. If set too high, WRED might not detect queue congestion in a timely manner and becomes ineffective. The default value should be sufficient for most users.
This object value is only used when the agentCosQueueMgmtType is set to wred(2) and is otherwise ignored.
What is agentCosQueueWredDecayExponent?
Sets the WRED decay exponent (0-15, default 9) controlling how quickly the average-queue-length calculation reacts to the current queue depth; a higher value smooths the average over a longer window. Only takes effect when agentCosQueueMgmtTypeIntf is wred(2) -- set too low, short bursts trigger excess drops, and set too high, WRED becomes slow to react to real congestion.
