Configuring Basic Settings Of A Vlan Interface; Configuration Procedure - H3C S3600V2 SERIES Layer 2-Lan Switching Configuration Manual

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.

Configuration procedure

To configure basic settings of a VLAN interface:
Step
1. Enter system view.
2. Create a VLAN interface
and enter VLAN interface
view.
3. Assign an IP address to the
VLAN interface.
4. Configure a description for
the VLAN interface.
5. Set the MTU for the VLAN
interface.
6. Restore the default settings
for the VLAN interface.

Remarks
N/A
If the VLAN interface already exists, you
enter its view directly.
•
When the device starts up with empty
configuration, the software initial settings
are used, and no VLAN interface exists
on the device.
•
When the device starts up with the
default configuration file, the software
default settings are used, and VLAN
interface 1 exists on the device.
For more information about the initial
settings and default configuration file, see
Fundamentals Configuration Guide.
Optional.
•
When the device starts up with empty
configuration, the software initial settings
are used, and no IP address is configured
for a VLAN interface.
•
When the device starts up with the
default configuration file, the software
default settings are used, and VLAN
interface 1 automatically obtains an IP
address through DHCP.
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.
