5-4-4. Port Controls
The menu allows changing of port configurations.
State: User can disable or enable each port.
Negotiation: User can set auto negotiation mode for each port to Auto,
Nway (specify the speed/duplex on this port and enable auto-negotiation) or
Force.
Speed: User can set 100Mbps or 10Mbps speed on Ports 1 to 24. User can
set 1000Mbps, 100Mbps or 10Mbps speed on Ports 25 and 26, depending
on module installed.
Duplex: User can set full-duplex or half-duplex mode for each port.
Flows control: User can set flow control function to enabled (ON) or
disabled (OFF) in Full Duplex mode.
Back Pressure: User can set backpressure to enabled (ON) or disabled
(OFF) in Half Duplex mode.
Band Width: Ports 1 to 24 support by-port ingress and egress rate control.
For example, if port 1 is set to 10Mbps, you can set it’s effective egress rate
to 1Mbps and ingress rateto 500Kbps. The MIL-SM2401M will perform flow
control or backpressure to confine the ingress rate to meet the specified
rate.
In: Enter the port effective ingress rate. The valid range is 0 to 1000. The
unit is 100K.
0: disable rate control.
1 to 1000: valid rate value
Out: Enter the port effective egress rate. The valid range is 0 to 1000.
The unit is 100K.
0: disable rate control.
1 to 1000: valid rate value.
Priority: This static priority is based on each port setting. If the port priority
is set high, incoming frames from this port will always be high priority
frames.
Security: A port in security mode will be “locked” unless address learning is
enabled. Only the incoming packets with SMAC already existing in the
address table can be forwarded normally. User can disable the port from
learning any new MAC addresses, and then use the static MAC
