The administrator must assign each port to the VLAN group in which it participates before the VLANs are enabled on the switch. When different devices are placed on the same Virtual Local Area Network (VLAN), the devices can talk to each other efficiently. By default, all the ports are assigned to VLAN1 as untagged port members. To participate in one or more VLANs and carry traffic for other network and host devices, add the port as a tagged port, otherwise add the port to the VLAN as an untagged port. The purpose of this document is to assign ports to multiple VLANs on the SFE/SGE Managed Switches.

Ports to Multiple VLANs
Step 1. Log in to the web configuration utility and choose Bridging > VLAN Management > VLAN to Port. The VLAN to Port page opens:
• The Port field displays the number of the port that is to be assigned to a VLAN group(s).
• The Mode field displays the operation state of the port. The possible option are:
– General — Represents that the port concerns with tagged or untagged user-defined VLAN.
– Access — Represents that the port concerns with untagged VLAN and the packet types cannot be designated.
– Trunk — Represents that the port concerns with tagged VLAN except for one.
– Customer — Represents that the port concerns with untagged VLAN.
• The VLANs field represents the PVID (port VLAN ID). A PVID is a default VLAN ID which is used to define the VLAN to which the port is connected.
• The LAG field represents whether the port is a member of a LAG or not. If the port is a member of a LAG then the port cannot be configured to a VLAN.
Step 2. Click the Join VLAN button on the desired port to assign it to one or more VLANs. The Join VLAN to Port window appears:
Step 3. Click the specific VLAN which you want the port to join and click >>.
Step 4. (Optional) Click the specific VLAN from which you want the port removed and click <<.
Note: An administrator can assign up to 20 VLANs to a single port.
Step 5. Click the desired radio button for the Tagging field. The possible options are:
• Tagged — The interface is a member of the chosen VLAN and packets sent from this interface destined to the chosen VLAN have the packet tagged with the VLAN ID.
• Untagged — The interface is a member of the chosen VLAN and packets sent from this interface destined to the chosen VLAN are not tagged with the VLAN ID. A port can be added as untagged only to one VLAN.
Step 6. Click Apply. The device is updated and the administrator is directed to the VLAN to Port page.
Caution: This only saves your configuration to the running configuration file. This means any changes made will be lost if the device is rebooted. If you wish to save these changes even after a system reboot, you need to copy the running configuration file to the startup configuration file. See Copy Configuration File on SFE/SGE Series Managed Switchesfor more information on how to do this.
