Administrator

Modifies the traffic congestion settings for a specified port or all ports. You can change the minimum and maximum buffer thresholds, in cells, for each priority queue on a port. Cell buffer memory then reserves the minimum buffer size for cells on the specified priority queue of that port. Cells are discarded when the maximum buffer threshold is reached.
