Description: This attribute indicates the congestion state of the receive cell memory on this FP.
This attribute indicates which rxCellMemoryThresholds corresponds to the current value of rxCellMemoryUsage. The congestion state is used to determine if cells of a particular discard priority (DP) are discarded before being queued for processing on this FP.
The congestion state of receive cell memory is indicated by a numeric value ranging from 3 to 0. When receive cell memory is in congestion state 'x', traffic with DP > 'x' is discarded before processing. Traffic with DP < 'x' may be queued for processing, depending on the congestion level of the processor or bus queue. Traffic with DP = 'x' may be either queued or discarded depending on how close the value of rxCellMemoryUsage is to the next threshold as displayed in rxCellMemoryThresholds. For example, CLP1 traffic is queued until the value indicated by rxCellMemoryUsage equals the value indicated in rxCellMemoryThresholds 3. At that point, CLP1 traffic is discarded.
What is lpEngArcRxCellMemoryCongestionState?
Reports the receive cell memory's congestion level (0-3) on this FP: traffic with discard priority greater than the current state is dropped before further processing, so an admin sees this drop toward 0 as the FP begins shedding lower-priority incoming ATM cells.
