agentCosQueueMgmtTailDropThreshold
Module: EdgeSwitch-QOS-COS-MIB
OID (symbolic): EdgeSwitch-QOS-COS-MIB::agentCosQueueMgmtTailDropThreshold
OID (numeric): 1.3.6.1.4.1.4413.1.1.3.3.2.5.1.2
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?
Obsolete tail-drop threshold for this queue/drop-precedence combination, expressed in sixteenths of the device's overall queue size, above which all packets at this drop precedence are discarded; only used when queue management is taildrop.
