Configuring basic VLAN settings
Configuration restrictions and guidelines
• As the default VLAN, VLAN 1 cannot be created or removed.
• You cannot manually create or remove VLANs reserved for special purposes.

Configuring basic settings of a VLAN interface
You can use VLAN interfaces to provide Layer 3 communication between hosts of different VLANs. 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 the IP address as the gateway address for the devices in
the VLAN, so that traffic can be routed to other IP subnets.
Before you create a VLAN interface for a VLAN, make sure that the VLAN already exists.
To configure basic settings of a VLAN interface:
