agentCosQueueMgmtTailDropThreshold
Module: NETGEAR-QOS-COS-MIB
OID (symbolic): NETGEAR-QOS-COS-MIB::agentCosQueueMgmtTailDropThreshold
OID (numeric): 1.3.6.1.4.1.674.10895.5000.2.6132.1.1.3.3.2.5.1.2
Node type: OBJECT-TYPE
Type: Sixteenths
Access: read-write
Description: Tail drop queue threshold above which all packets are dropped for the current drop precedence level. The value specifies the threshold based on a fraction of the overall device queue size in terms of sixteenths (0/16, 1/16, 2/16, ... 16/16). Since device implementations vary, the actual value deployed may be rounded up or down accordingly.
The default value is calculated from the agentCosQueueIndex and agentCosQueueDropPrecIndex as shown in the following table (values listed for drop precedence levels 1, 2, and 3, respectively): Queue Index 0: 16, 14, 12 Queue Index 1: 16, 14, 12 Queue Index 2: 16, 14, 12 Queue Index 3: 16, 14, 12 Queue Index 4: 16, 14, 12 Queue Index 5: 16, 14, 12 Queue Index 6: 16, 14, 12 Queue Index 7: 16, 14, 12
This object is only used when agentCosQueueMgmtType is set to taildrop(1).
What is agentCosQueueMgmtTailDropThreshold?
An obsolete object that specified the tail-drop threshold as a fraction of queue size in sixteenths (0/16-16/16); superseded by the percentage-based agentCosQueueMgmtPercentTailDropThreshold. Admins should configure the newer percent-based object instead.
