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