agentCosQueueMgmtWredDropProbScale
Module: NETGEAR-QOS-COS-MIB
OID (symbolic): NETGEAR-QOS-COS-MIB::agentCosQueueMgmtWredDropProbScale
OID (numeric): 1.3.6.1.4.1.674.10895.5000.2.6132.1.1.3.3.2.5.1.5
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: A scaling factor used for the WRED calculation to determine the packet drop probability for the current drop precedence level. The value is specified as a number S from 1-15 and is used in the formula: 1/(2** S), meaning one packet is dropped out of every (2** S). Packet dropping begins when agentCosQueueMgmtWredMinThreshold is reached and proceeds linearly up to the (2**S) value specified by this object until the agentCosQueueMgmtWredMaxThreshold is reached, beyond which all packets are dropped. Smaller values of S produce a steeper slope, hence a higher incidence of randomly dropped packets.
The default value is 10, which corresponds to a drop rate of 1 out of every (2**10)=1024 packets.
This object is only used when agentCosQueueMgmtType is set to wred(2).
What is agentCosQueueMgmtWredDropProbScale?
An obsolete object that specified the WRED drop-probability scaling factor S (1-15) in the formula 1/(2**S); superseded by the percentage-based agentCosQueueMgmtWredDropProbability. Admins should configure the newer percent-based object instead.
