4-2-2. Port Configuration  

 
Function name: 

Port Configuration 

Function description: 

Port Configuration is applied for the settings of the ports on the switch. By this function, you can set 
or reset the values for Mode and Flow Control. 

Parameter description:

 

Enable Jumbo Frames: 

This function support jumbo frames of up to 9600 bytes, Just tick the check box (

;

) to enable 

it. 

Default: disable 

Link: 

     Show link status of this port. 

Mode:  

Set the speed and duplex of the port. If the media is 1Gbps fiber, there are three modes to 
choose: Auto Speed, 1000 Full and Disable. If the media is TP, the Speed/Duplex is comprised 
of the combination of speed mode, 10/100/1000Mbps, and duplex mode, full duplex and half 
duplex. The following table summarizes the function the media supports. 

Media type 

NWay 

Speed 

Duplex 

1000M TP 

ON/OFF 

10/100/1000M 

Full for all, Half for 10/100 

1000M Fiber 

ON/OFF 

1000M 

Full 

In Auto Speed mode, no default value. In Forced mode, default value depends on your setting. 

Flow Control:  

You can just check the check box (

;

) to enable flow control. If flow control is set to Enable, 

both parties can send PAUSE frame to the transmitting device(s) if the receiving port is too 
busy to handle.  When it is set to Disable, there will be no flow control in the port. It drops the 
packet if there is too much to handle.   

Default: Disable
