For example VLAN2 is correct; VLAN 2 will give an error. The VLAN name can be any 15 alphanumeric characters. Special characters are not allowed.


4-3-4-1. VLAN Configure

Choose a VLAN

In the VLAN Configure menu select the type of VLAN you want to configure: No VLAN (default), Port Based, 802.1Q, or 802.1Q with GVRP. Save the configuration.

There are 4 different options for VLANs to choose from using the space bar: Disabled, Port Based, 802.1Q and 802.1Q with GVRP.

To configure a new VLAN, select Edit and then use the tab key to select items you want to configure. The space bar allows you to select the different options.

After adding a VLAN group, the configuration option Edit a VLAN Group will allow you to change the membership by adding or deleting ports.

Port Based VLANs

These VLANs only apply to this switch. The VLANs can be overlapping, meaning that any port can belong to more than one VLAN. One configuration that is common for port based VLANs is to have all the ports on the switch on separate VLANs except for the port that has the server connected. The port connected to the server belongs to all the VLANs. This enables security between ports but allows all ports access to the server. Up to 256 different port based VLANs may be configured.


If IEEE802.1Q VLANs is selected, all the ports will belong to the default VLAN 1.


If more than one VLAN is necessary, the additional VLANs may be created.

PVID (Port VID): Set the port VLAN ID that will be assigned to untagged traffic on a given port. This feature is useful for accommodating devices that you want to participate in the VLAN, but don’t support tagging. Only one untagged VLAN is allowed per port. Other VLANs need to be tagged.

Ingress Filter 1: If this is set, the port will only forward packets with VID (VLAN ID) matching this port’s configured VID. Press the Space key to choose forward or drop the frame with the VID not matching this port’s configured VID.

Ingress Filter 2: Drop untagged frame. Press the Space key to choose drop or forward the untagged frame.
