Configuring VLAN interfaces
Before creating a VLAN interface, you must create the corresponding VLAN in Network > VLAN. For
more information, see " Configuring VLANs ."
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 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. Select Network > VLAN Interface from the navigation tree.
2. Click Create to enter the page for creating a VLAN interface.
