Configuring VLANs > Creating VLANs

Creating VLANs

VLANs can be created in either the Network Workshop or the Device Workshop.

VLANs are not created on specific devices, but are available network-wide. Once created, a network-wide VLAN can be associated with an Ethernet port on the network, in turn creating an actual VLAN. Nothing is created on any device when a network-wide VLAN is created. A VLAN is actually created only when it is associated with an Ethernet port.

To create a VLAN:

1. On the Configuration menu, select Create, and click Virtual LAN.

The Create VLAN Interface dialog box appears.

2. Set the VLAN parameters (Table 27).

 Table 27:  VLAN Parameters

3. Click OK. The VLAN is added to the VLAN Name list.

Configuring a VLAN

You can view and configure a VLAN by choosing from the Configuration menu or the pop-up menu that is displayed by right-clicking an object.

You can change a VLAN ID or delete the VLAN if no upper bindings have been configured on any of its associated ports.

Modifying the VLAN ID changes the VLAN ID for every subinterface across all devices that have this VLAN associated with them. Deleting a VLAN removes all subinterfaces with the VLAN ID of the VLAN, provided no upper bindings exist on any of its associations.
