lpAruTxFrameFreeListCongestionState 1.3.6.1.4.1.562.2.4.1.12.20.100.1.56

This attribute indicates the congestion state of the transmit frame free list on this ATM-FP. The congestion state of a free list is indicated by a numeric value ranging from 0 to 3. When a free list is in a congested state x, only traffic with discard priority (DP) 0 to x will be stored. Traffic with DP > x will be discarded. Therefore, if the congestion state is 3, there is no congestion and all traffic is stored. Likewise, when the congestion state is 0, there is maximum congestion and only traffic with DP=0 will be stored.
