Note 2: The priority of Gigabit Fiber port is higher than Copper. 21 To change the port setting, click on the ID parameter to enter the selected port to configure its Speed/Disable and Flow control. Figure 18. Port Setting Speed/Disable: This setting has six modes--100M Full, 100M Half, 10M Full, 10M Half, Auto and Disable--for speed or port disable selections. Flow Control: This setting determines whether or not the Switch will be handling flow control. Set Flow Control to Enable for avoiding data transfer overflow. 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, the flow control will automatically be set to Disable. Default Priority: The Default Priority is specific the 802. 1P QoS priority level to related port, all of the received data packet will follow the Default Priority level forwarding data packet to other port. 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, Port VLAN Setting, and Port Egress Setting. 22 VID Table Setting: 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 48, select Untag Port, Tag Port, or Not Member for each port. To save the VID group, press "Apply" button. To remove the selected VID group, select the VID group and press "Remove the VID" button. To modify the VID group setting, select the VID group and change the setting, and press "Apply" button to save the settings. Figure 19. VID Table Setting Port VID Setting: When you select Port VLAN setting, fill in each port's PVID value between 1 and 4094. Figure 20. 23 Port Egress Setting: The Port Egress is used to set the 802. 1Q VLAN Egress rule in each port; the selected port will include the TCI (Tag Control Information) data packets. Figure 21. Port Egress Setting Trunk Setting The Trunk function enables the Switch to cascade two or more devices with larger bandwidths. There are ten Trunking groups to be set, and there are default ports in each member.
