36 CHAPTER 4: CONFIGURING THE SWITCH VLAN Click Device, then VLAN on the menu. A screen appears with seven tabs that include: ■ Setup ■ Modify VLAN ■ Modify Port ■ Rename ■ Remove ■ Port Detail ■ VLAN Detail Setup Use the Setup screen to create VLANs on the Switch. To propagate information about VLAN groups used on this Switch to external devices, you must specify a VLAN ID for each VLAN. Figure 25 Setup Screen Available option on the Setup screen include: ■ VLAN ID - ID of configured VLAN (1-4094, no leading zeroes) For examples on setting up VLANs, refer to "Sample VLAN Configurations". CAUTION: At least one port must always be an untagged member of VLAN 1 (the management VLAN). If you choose to connect all ports to VLANs other than VLAN 1, you will no longer be able to access the Web interface. If this happens, you will need to reset the Switch to factory settings. By default, all ports belong to VLAN 1 as an untagged member. However, they can belong to multiple VLANs as a tagged member. Also, newly created VLANs will initially have no ports associated with them. Modify VLAN Use the Modify VLAN screen to change the VLAN to which a port belongs, and configure the port to communicate with all other VLANs, or a selected VLAN.
