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
