5.2.1. Creating a VLAN Interface

Using the Add VLAN button, the administrator can create sub-interfaces. To create a VLAN, provide the following settings:




Enables the VLAN.


The VLAN name. Assigned automatically based on the physical port name and the VLAN tag.


An optional interface description.


Specify the interface type as Layer 3 or Mirror. An interface operating in the Layer 3 mode can be assigned an IP address and used in firewall rules, content filtering, and other rules. This is the standard operating mode of a network interface. An interface operating in the Mirror mode can receive traffic from a SPAN port of network equipment for subsequent analysis.

VLAN tag

The sub-interface number. Up to 4094 interfaces can be created.

Node name

The node name in the cluster where this VLAN is being created.


The physical interface on which the VLAN is being created.


The zone to which the VLAN belongs.

Netflow profile

The Netflow profile to send statistical data to the Netflow collector. You can read about Netflow profiles in chapter Netflow Profiles.


The IP address assignment method: no address, a static IP address, or a dynamic IP address obtained using DHCP.

DHCP relay

Configure DHCP relay for a VLAN interface. Enable DHCP relay, enter the IP address of the interface on which the relay function is added in the UserGate address field, and specify one or more DHCP servers where client DHCP requests are to be forwarded.
