Back Pressure— Indicates if back pressure is enabled or disabled
on the port. Back pressure is used by a port during periods of
packet congestion to temporarily stop its network counterpart from
transmitting more packets. This prevents a buffer overrun and the
subsequent loss and retransmission of network packets. A port
initiates back pressure by transmitting on the shared link to cause a
data collision, which causes its link partner to cease transmission.
The default setting is “Disabled.”
Back Pressure Limit— Indicates the threshold level for back
pressure on the port. Specifies the number of cells for back
pressure. The default value is 7935 cells.
Flow Control— Indicates if flow control (send and receive) is
enabled or disabled on a port. If flow control is enabled, a port
sends pause packets when it reaches the point of packet
congestion. Also, the port stops transmitting packets when it
receives pause packets from its local or remote counterpart. When
flow control is disabled, the port sends pause packet regardless of
packet congestion. In addition the port continues transmitting
packets when it receives pause packets from its local or remote
counterpart. The default is “Disabled.”
Flow Control Limit— Indicates the threshold level for flow control
on a port. The default value is 7935.
Description— Indicates the description of a port. To specify this
field, see “Changing the Port Settings” on page 72.
