Figure 16. Port Configuration To change the port setting, click on the ID parameter to enter the selected port to configure its Speed/Disable, Flow control, and QoS setting. Figure 17. Speed: This setting has six modes-1000M Full, 100M Full, 100M Half, 10M Full, 10M Half, Auto, and Disable-for speed or port disable selections. Note: If the speed set to 100M full mode or 10M full mode, flow control should have the fixed setting set to disable. Flow Control: This setting determines whether or not the Switch will be handling flow control. Set FlowCtrl to Enable for avoiding data transfer overflow. Or if it is set to Disable, there is either no flow control or other hardware/software management. When the port is set to forced mode, then the flow control will automatically set to Disable. Note: Sending packets between two groups may cause packet loss. QoS: In some ports that need to have a high priority to manage the data transfer, QoS should be changed. Set the port's QoS to high to determine that the port will always transfer its data first. VLAN Settings (Virtual Local Area Network) A VLAN is a collection of switch ports that make up a single broadcast domain. You can configure a VLAN for a single switch, or for multiple switches. When you create a VLAN, you can control traffic flow and ease the administration of moves, adds, and changes on the network, by eliminating the need to change physical cabling. On VLAN settings, there are two main settings, VID Table Setting and Port VLAN Setting. VID: Select the VID group that you set. When you select VID Table Setting, press "Add new VID" to create new VID group, from port 01 ~ port 16. Select Untag Port, Tag Port, or Not Member for each port. To save the VID group, press the "Apply" button. To remove the selected VID group, select the 24

Speed:
This setting has six modes—
1000M Full
,
100M Full
,
100M Half
,
10M Full
,
10M Half
,

and Disable
—for speed or port
disable selections.
Note:
If the speed set to 100M full mode or 10M full mode, flow control should have the fixed setting set to disable.
Flow Control:
This setting determines whether or not the Switch will be handling flow control. Set
FlowCtrl
to
Enable
for avoiding data transfer
overflow. Or if it is set to
Disable
, there is either no flow control or other hardware/software management.
When the port is set to
forced mode
, then the flow control will automatically set to
Disable
.
Note:
Sending packets between two groups may cause packet loss.
QoS:
In some ports that need to have a high priority to manage the data transfer, QoS should be changed. Set the port’s QoS to high to
determine that the port will always transfer its data first.
