Chapter 5: Port Parameters
82 Section I: Basic Operations
Enabled - The port discards egress unknown unicast packets.
Disabled - The port forwards egress unknown unicast packets. This is
the default setting.
Ingress Unknown Multicast Filter
Use this parameter to configure a port to forward or discard ingress
unknown multicast packets. The possible settings are:
Enabled - The port discards ingress unknown multicast packets.
Disabled - The port forwards ingress unknown multicast packets. This
is the default setting.
Egress Unknown Multicast Filter
Use this parameter to configure a port to forward or discard egress
unknown multicast packets. The possible settings are:
Enabled - The port discards egress unknown multicast packets.
Disabled - The port forwards egress unknown multicast packets. This
is the default setting.
Flow Control
Sets flow control on a port. This option only applies to ports operating
in full-duplex mode. A switch port uses back pressure to control the
flow of ingress packets. The switch sends 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. The
possible settings are:
Auto - The port uses flow control if it detects that the end node is using
it.
Disabled - No flow control on the port. This is the default.
Enabled - Flow control is activated.
For further information about flow control, refer to Chapter 6, “Port
Parameters,” in the AT-S63 Management Software Menus Interface
User’s Guide.
Back Pressure
Use this parameter to set back pressure on a port. This option only
appears for ports operating in half-duplex mode. A switch port uses
back pressure to control the flow of ingress packets. The possible
settings are:
Enabled - Back pressure is enabled.
Disabled - Back pressure is disabled. This is the default.
