Chapter 2: Port Parameters
46 Section I: Basic Operations
Ingress Unknown Unicast Filter
Use this parameter to configure a port to forward or discard unknown
ingress unicast packets. The possible settings are:
Enabled - The port discards unknown ingress unicast packets.
Disabled - The port forwards unknown ingress unicast packets. This is
the default setting.
Egress Unknown Unicast Filter
Use this parameter to configure a port to forward or discard unknown
egress unicast packets. The possible settings are:
Enabled - The port discards unknown egress unicast packets.
Disabled - The port forwards unknown egress unicast packets. This is
the default setting.
Ingress Unknown Multicast Filter
Use this parameter to configure a port to forward or discard unknown
ingress multicast packets. Possible settings are:
Enabled - The port discards unknown ingress multicast packets.
Disabled - The port forwards unknown ingress multicast packets. This
is the default setting.
Egress Unknown Multicast Filter
Use this parameter to configure a port to forward or discard unknown
egress multicast packets. Possible settings are:
Enabled - The port discards unknown egress multicast packets.
Disabled - The port forwards unknown egress 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 flow control 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. Possible
settings are:
Disabled - No flow control on the port. This is the default.
Enabled - Flow control is activated.
Back Pressure
Use this parameter to set backpressure on a port. This option only
appears for ports operating in half-duplex mode. A port uses
backpressure to control the flow of ingress packets. Possible settings
are:
Enabled - Backpressure is enabled.
