Description: This attribute is migrated to the Lp/n Eng Arc Ov attribute txCellMemoryAllocation. It is converted from frame percentage to cell percentage by subtracting this value from 100.
This attribute specifies the percentage of the transmit CQM memory which should be allocated to the transmit frame free list on the ATM-FP. The remaining transmit CQM memory is allocated to the transmit cell free list. Frame memory is used for trunks, ATM VCC testing and for inter-card communication. There is an absolute minimum quantity of frame buffers which is required by ATM software on the FP. If the value of this attribute is smaller than the absolute minimum, the ATM software will allocate the minimum required, rather than the actual number requested.
The actual percentage of the transmit CQM memory allocated to the transmit frame free list is indicated by the Aru txFrameMemoryAllocation attribute. A difference between the provisioned and the operational values may exist due to the requirement for a minimum number of frame buffers or rounding during computation within the FP.
What is lpArcTxFrameMemoryAllocation?
Sets what percentage (0-100, default 50) of the FP's transmit CQM memory is reserved for the transmit frame free list -- used for trunk traffic, ATM VCC testing, and inter-card messages -- with the remainder going to the transmit cell free list. The FP enforces an absolute minimum of frame buffers, so the value actually applied may differ slightly and is visible in the corresponding lpAru operational attribute.
