Back Pressure
You can use this selection only if the port or ports you specified
are operating at half-duplex mode. When you specify that a port
is in this mode and it has a packet that is pending transmission,
then the software suspends the JAM pattern before sending the
packet. After the packet is sent, the JAM pattern resumes.
To select a value, click the circle next it. Possible values are:
❑ Enabled - Indicates back pressure is activated on this port. When
the port is receiving too many packets, the port sends a signal to
the end node to stop sending information.
❑ Disabled - Indicates back pressure is not activated on this port.
When the port is receiving too many packets, the port does not
send a signal to the end node to stop sending information. This is
the default.
Flow Control
Flow control applies only to ports operating in full-duplex mode.
The switch uses a special pause packet to stop the end node from
sending frames. The pause packet notifies the end node to stop
transmitting for a specified period of time.
To select a value, click the circle next it. Possible values are:
❑ Auto - Indicates the port conforms to the flow control setting of
the end node. For example, if flow control is active on the end
node then flow control is active on this port. Also, if flow control is
not active on the end node, then flow control is not active on this
port. This is the default.
❑ Disabled - Indicates that no flow control occurs on the port.
❑ Enabled - Indicates that flow control occurs on the port.
MDI/MDIX Crossover
The operating configuration of the port. Auto indicates that the
port automatically determines the appropriate MDI or MDI-X
setting.
