Description: This attribute indicates the maximum txFrameFreeListSize and the discard thresholds of the transmit frame free list. The transmit frame free list is the memory (in units of ATM cells) used for storing frames to be transmitted by the Lp.

The first parameter indicates the total size of the transmit frame free list. This is derived based upon the connectionPoolCapacity and the txFrameMemoryAllocation under the ARC component.

When the txFrameFreeListSize decreases to the second value, the txFrameFreeListCongestionState changes from 3 to 2. In congestion state 2, traffic with discard priority (DP) = 3 is discarded. This threshold is set approximately at 25 percent of the first value, the maximum transmit frame free list size.

When the txFrameFreeListSize decreases to the third value, the txFrameFreeListCongestionState changes from 2 to 1. In congestion state 1, traffic with discard priority (DP) = 2 is discarded. This threshold is set approximately at 20 percent of the first value, the maximum transmit frame free list size.

When the txFameFreeListSize decreases to the fourth value, the txFameFreeListCongestionState changes from 1 to 0. In congestion state 0, traffic with discard priority (DP) = 1 is discarded. This threshold is set approximately at 10 percent of the first value, the maximum transmit frame free list size.
