Configuring Basic Settings Of A Vlan Interface - H3C S7500E-X Configuration Manual

NOTE:
• As the system default VLAN, VLAN 1 cannot be created or deleted.
• Before you delete a dynamic VLAN or a VLAN locked by an application, you must first remove
the configuration from the VLAN.

Configuring basic settings of a VLAN interface

For hosts of different VLANs to communicate at Layer 3, 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 and
assign an IP address to it. The VLAN interface acts as the gateway of the VLAN to forward packets
destined for another IP subnet.
When you configure a VLAN interface, follow these restrictions and guidelines:
•
Before you create a VLAN interface for a VLAN, create the VLAN first.
•
You cannot create a VLAN interface for a sub-VLAN. For more information about sub-VLANs,
see "Configuring super
•
You cannot create VLAN interfaces for secondary VLANs that have the following
characteristics:
Associated with the same primary VLAN.
Enabled with Layer 3 communication in VLAN interface view of the primary VLAN interface.
For more information about secondary VLANs, see

N/A
If the VLAN interface already exists,
you enter its view directly.
By default, no VLAN interface is
created.
By default, no IP address is assigned to
a VLAN interface.
The default setting is the VLAN
interface name. For example,
Vlan-interface1 Interface.
The default setting is 1500 bytes.
By default, the expected bandwidth (in
kbps) is the interface baud rate divided
by 1000.
