Pressure Uses a special packet to halt the transmission of the
JAM pattern if there is a pending packet for
transmission while the port is transmitting the JAM
pattern.
Possible settings for this parameter are:
• Disable (default)
• Enable: If you select “Enable” when the port is running
“half-duplex” mode and the number of packets
received exceed the received threshold of the port
(which is 160 for 10/100 port, and 664 for 1 Gig port),
the port will transmit a JAM pattern for a short
amount of time.
NOTE: This parameter only applies to the port that is in
half-duplex mode.
