Configuring basic settings of a VLAN interface

VLAN interface overview

For hosts of different VLANs to communicate, you must use a router or Layer 3 switch to perform Layer 3
forwarding. You use VLAN interfaces to achieve this.
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 traffic
destined for an IP subnet different from that of the VLAN.

Configuration procedure

Follow these steps to configure basic settings of a VLAN interface:
To do...
Enter system view
Create a VLAN interface and
enter VLAN interface view
Assign an IP address to the
VLAN interface
Configure the description of the
VLAN interface
Set the MTU for the VLAN
interface
Restore the default settings for
the VLAN interface
Shut down the VLAN interface
NOTE:
Before you create a VLAN interface for a VLAN, create the VLAN.
Use the command...
system-view
interface vlan-interface
vlan-interface-id
ip address ip-address
{ mask | mask-length }
[ sub ]
description text
mtu size
default
shutdown
117
Remarks
—
Required
If the VLAN interface already exists, you
enter its view directly.
Optional
By default, no IP address is assigned to any
VLAN interface.
Optional
By default, the description of a VLAN is the
VLAN interface name. For example,
Vlan-interface1 Interface.
Optional
By default, the MTU is 1500 bytes.
Optional
Optional
By default, a VLAN interface is in the up
state. The VLAN interface is up if one or
more ports in the VLAN is up, and goes
down if all ports in the VLAN go down.
A VLAN interface shut down with the
shutdown command is in the DOWN
(Administratively) state until you bring it up,
regardless of how the state of the ports in the
VLAN changes.
