Table 5-2. Media supported.
Media Type Auto-negotiation 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, there is no default value. In Forced mode, the default value depends on your setting.
Flow Control: You can tick the check box to enable flow control. If flow control is set to Enable, both parties can send PAUSE
frames to the transmitting device(s) if the receiving port is too busy to handle the traffic. When it is set to Disable, there will be
no flow control in the port. It drops the packet if it is too much to handle. The default is disable.
5.2.3 VLAN Mode Configuration
The switch supports Port-based VLAN and Tag-based VLAN (8 02.1q). Its VLAN mode supports 10 active VLANs and the available
VLAN ID range is from 1–4094. VLAN configuration is used to divide a LAN into smaller ones. With proper configuration, you can
gain not only improved security and increased performance, but also save a lot of VLAN management effort.
Function name: VLAN Mode Setting
Function description: The VLAN Mode Selection function includes four modes: Port-based, Tag-based, Metro mode, or Disable.
Choose one of them via the drop-down menu. Then, click on the “Apply” button, and the settings will take effect immediately.
Figure 5-7. Select VLAN Mode
Parameter description:
VLAN Mode:
Port-based: Port-based VLAN is defined by port. Any packet coming in or going out from any one port of a port-based VLAN will
be accepted. A no-filtering criterion applies in port-based VLAN. The only criterion is the physical port you connect to. For
example, a port-based VLAN named PVLAN-1 contains port members Port 1, 2, 3, and 4. If you are on Port 1, you can
communicate with Port 2, 3, or 4. If you are on Port 5, then you cannot talk to them. Each port-based VLAN you build must be
assigned a group name. This switch can support up to 12 groups.
Tag-based: Tag-based VLAN identifies its members by VID. This is quite different from port-based VLAN. If there are any more
rules in ingress filtering list or egress filtering list, the packet will be screened with more filtering criteria to determine if it can be
forwarded. The switch supports a supplement of 802.1q. For more details, see VLAN in Section 4.6.
Each tag-based VLAN you built must be assigned a VLAN name and a VLAN I D. A valid VLAN ID is 1–4094. Users can create up
to 16 VLANs simultaneously.
5.2.4 VLAN Group Configuration
Function name: Tag-Based VLAN Configuration (Tag based VLAN mode)
Function description: The VLAN membership configuration for the selected switch can be monitored and modified here. Up to
4094 VLANs are supported. This page allows for adding and deleting VLANs as well as adding and deleting port members of
each VLAN.
