Creating VLANs You can create a VLAN, but this has no effect until the VLAN is attached to at least one port, either manually or dynamically. Ports must always belong to one or more VLANs. The 300 Series device supports up to 4K VLANs, including the default VLAN. Each VLAN must be configured with a unique VID (VLAN ID) with a value from 1 to 4094. The device reserves VID 4095 as the Discard VLAN. All packets classified to the Discard VLAN are discarded at ingress, and are not forwarded to a port. To create a VLAN: STEP 1 Click VLAN Management > VLAN Settings. This page displays the following fields for all VLANs: • VLAN ID—User-defined VLAN ID. • VLAN Name—User-defined VLAN name. • Originators—VLAN type: - GVRP—VLAN was dynamically created through Generic VLAN Registration Protocol (GVRP). - Static—VLAN is user-defined. - Default—VLAN is the default VLAN. STEP 2 Click Add to add a new VLAN. The page enables the creation of either a single VLAN or a range of VLANs. STEP 3 To create a single VLAN, select the VLAN radio button, enter the VLAN ID (VID), and optionally the VLAN Name. To create a range of VLANs, select the Range radio button, and specify the range of VLANs to be created by entering the Starting VID and Ending VID, inclusive. When using the Range function, the maximum number of VLANs you can create at one time is 100. STEP 4 Click Apply to create the VLAN(s).
Configuring Port to VLAN Use the Port to VLAN page to display and configure the ports within a specific VLAN. To map ports or LAGs to a VLAN: STEP 1 Click VLAN Management > Port to VLAN. STEP 2 Select a VLAN and the interface type (Port or LAG), and click Go to display or to change the port characteristic with respect to the VLAN. The port mode for each port or LAG appears with its current port mode (Access, Trunk, General or Customer) configured from the Interface Settings page. Each port or LAG appears with its current registration to the VLAN. STEP 3 Change the registration of an interface to the VLAN by selecting the desired option from the following list: • Forbidden—The interface is not allowed to join the VLAN even from GVRP registration. When a port is not a member of any other VLAN, enabling this option on the port makes the port part of internal VLAN 4095 (a reserved VID). • Excluded—The interface is currently not a member of the VLAN. This is the default for all the ports and LAGs. The port can join the VLAN through GVRP registration. • Tagged—The interface is a tagged member of the VLAN. • Untagged—The interface is an untagged member of the VLAN. Frames of the VLAN are sent untagged to the interface VLAN. • Multicast TV VLAN—The interface used for Digital TV using Multicast IP. The port joins the VLAN with a VLAN tag of Multicast TV VLAN. See Access Port Multicast TV VLAN for more information. • PVID—Select to set the PVID of the interface to the VID of the VLAN. PVID is a per-port setting. STEP 4 Click Apply. The interfaces are assigned to the VLAN, and written to the Running Configuration file. You can continue to display and/or configure port membership of another VLAN by selecting another VLAN ID.
