Sixteenths
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).
