RXonis sent when the number of buffers used by the traffic falls below the specified level(default is 4). Rxoff is sent when the number of buffers used goes above the specifiedvalue (default is 6). The "flowcontrol" command is used to set the above thresholds. ItDOES NOT enable or DISABLE flow controlDisabled (default) – The port will not generate flow control packets and drops receivedflow control packetsEnabled: The port uses 802.3x Link Layer Flow Control, generates flow control packets,and processes received flow control packets.With the port speed set to auto (the default) and flow control set toenabled; the switch negotiates flow control on the indicated port. If theport speed is not set to auto, or if flow control is disabled on the port,then flow control is not used.To set flow controlSyntax flowcontrol xonlimit= xofflimit=125
