lp Eng Arc Ov Rx Cell Memory Allocation

This attribute specifies the fraction of the receive memory which should be allocated to the reception of cells on an FP. The remaining receive memory is allocated for the reception of frames. Frame memory is used for trunks, ATM VCC testing and for inter- card communication. Cell memory is used for Atm Bearer Service, ATM SVCs and ATM PVCs. 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 allocates the minimum required, rather than the actual number requested. The actual percentage of the receive memory allocated to the receive cell memory is indicated by the Arc rxCellMemoryAllocation 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.
