agentCosQueueWredDecayExponent
Module: QOS-COS-MIB
OID (symbolic): QOS-COS-MIB::agentCosQueueWredDecayExponent
OID (numeric): 1.3.6.1.4.1.7244.2.3.3.2.3.1.4
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?
Tuning parameter (0-15, default 9) controlling how quickly WRED's average-queue-length calculation reacts to the current queue depth; setting it too low lets short traffic bursts trigger excessive drops, while setting it too high makes WRED slow to notice real congestion, so most admins should leave it at the default.
Examples
Walk all instances (SNMPv2c):
