PortTrafficCongestion
Use PortTrafficCongestion to manage traffic congestion at switch ports. You can program the values for the minimum
and maximum threshold (in number of cells) for a specified priority queue. If the number of cells received by the switch
on the specified priority queue for a port exceeds the maximum threshold, the switch discards the cell.
2 p›F
You program values for minimum and maximum threshold by entering index
numbers that correspond to cell numbers. Use MinMaxTableIndex to see the
correspondance between index numbers and cell numbers.
