Configuring VLAN interfaces

Before creating a VLAN interface, you must create the corresponding VLAN in Network > VLAN. For
more information, see

Overview

For hosts of different VLANs to communicate, you must use a router or Layer 3 switch to perform layer 3
forwarding. To achieve this, you can use VLAN interfaces.
VLAN interfaces are virtual interfaces used for Layer 3 communication between different VLANs. They do
not exist as physical entities on devices. For each VLAN, you can create one VLAN interface. You can
assign the VLAN interface an IP address, and specify it as the gateway of the VLAN to forward the traffic
destined for an IP network segment different from that of the VLAN.

Creating a VLAN interface

When you create a VLAN interface, you can select to assign an IPv4 address and an IPv6 link-local
address to the VLAN interface in this step or in a separate step. If you do not select to configure an IP
address, you can create the VLAN interface, and configure an IP address for the VLAN interface by
modifying it.
To create a VLAN interface:
1. From the navigation tree, select Network > VLAN Interface.
2. Click Create to enter the page for creating a VLAN interface.
"Configuring VLANs."
