SmartSwitch ATM Switch Reference Manual 2-235PortTrafficCongestionPortTrafficCongestionUse PortTrafficCongestion to manage traffic congestion at switch ports. You can program the values for the minimumand maximum threshold (in number of cells) for a specified priority queue. If the number of cells received by the switchon the specified priority queue for a port exceeds the maximum threshold, the switch discards the cell.Note You program values for minimum and maximum threshold by entering indexnumbers that correspond to cell numbers. Use MinMaxTableIndex to see thecorrespondance between index numbers and cell numbers.Operatorsmodify, showParametersParameter Description Value/Field Size Default[PortNumber] Port number on the switch.
