SYNTAX SEQUENCE OF AtmIfTxCellMemoryThresholdEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"This attribute is a vector which indicates the size and three discard
thresholds for transmit cell memory for this AtmIf. This attribute is
not applicable, and is not displayed on CQC-based ATM FPs.
Transmit cell memory used for storing ATM cells to be transmitted
by connections under this AtmIf. It includes all cells in connections
at the nrt-VBR or UBR service category. It includes cells in CBR or
rt-VBR connections which are doing per-VC queueing. It does not
include cells in CBR or rt-VBR connections which are allocated
from the dedicated buffer for CBR common queuing or rt-VBR
common queuing.
The first value indicates the transmit cell memory size. It is the
multiplication of the Lp/x Eng Arc Aqm/y txCellMemoryThreshold 0
attribute by the txCellMemoryPercentage attribute of this AtmIf.
The current value of txCellMemoryUsage together with the vector
of values in txCellMemoryThreshold determines the
txCellMemoryCongestionState. The congestion state determines
whether cells of a given discard priority (DP) are discarded or
queued for transmit.
When the txCellMemoryUsage attribute is between threshold 0 and
threshold 1, the txCellMemoryCongestionState indicates the value
0. In congestion state 0, traffic with DP >
