Parameters
interface-number: Specifies a VLAN interface number in the range of 1 to 4094.
Usage guidelines
Create the VLAN before you create the VLAN interface for a VLAN.
You cannot create VLAN interfaces for sub-VLANs.
Examples
# Create VLAN-interface 2, and enter its view.

Default
The MTU of a VLAN interface is 1500 bytes.
Views
VLAN interface view
Predefined user roles
network-admin
Parameters
size: Sets the MTU in bytes. The value range varies by interface card. .
Usage guidelines
If you configure both the mtu and ip mtu commands on a VLAN interface, the MTU set by the ip mtu command is used for fragmentation. For more information about the ip mtu command, see Layer 3—IP Services Command Reference.
Follow these guidelines when you set the MTU for a VLAN interface:
· The outgoing interface uses the MTU of 1280 bytes if its MTU is smaller than 1280 bytes and the incoming interface is on the specified cards. As a best practice, set the MTU of the outgoing interface to a value greater than 1280 bytes when the device is installed with the cards mentioned above.
· If a MIC subcard interface on the CSPEX-1104-E or CSPEX-1204 card is assigned to a VLAN, the MTU for the VLAN interface must be less than or equal to 2980. If you configure a MTU value greater than 2980, traffic through the VLAN interface is blocked. To resolve this problem, use the undo mtu command to restore the default and reconfigure an MTU.
Examples
# Set the MTU to 1492 bytes for VLAN-interface 1.
<Sysname> system-view
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface1] mtu 1492
Related commands

name
Use name to assign a name to a VLAN.
Use undo name to restore the default.
Syntax
name text
undo name
Default
The name of a VLAN is VLAN vlan-id. The vlan-id argument specifies the VLAN ID in a four-digit format. If the VLAN ID has fewer than four digits, leading zeros are added. For example, the name of VLAN 100 is VLAN 0100.

Usage guidelines
|
|
CAUTION: Executing the shutdown command on a VLAN interface will disconnect the link of the VLAN interface and interrupt communication. Use this command with caution. |
When a VLAN interface is not manually shut down, the following guidelines apply to the interface state:
· The VLAN interface is down if all ports in the VLAN are down.
· The VLAN interface is up if one or more ports in the VLAN are up.
When you use this command to shut down a VLAN interface, the VLAN interface remains in DOWN (Administratively) state. In this case, the VLAN interface state is not affected by the state of the ports in the VLAN.
Before you configure parameters for a VLAN interface, use this command to shut it down to prevent the configuration from affecting the network. After you complete the VLAN interface configuration, use the undo shutdown command to make the settings take effect.
To troubleshoot a failed VLAN interface, you can use the shutdown command and then the undo shutdown command on the interface to see whether it recovers.
In a VLAN, the state of each Ethernet port is independent of the state of the VLAN interface.
Examples
# Shut down VLAN-interface 2, and then bring it up.
<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] shutdown
[Sysname-Vlan-interface2] undo shutdown

Usage guidelines
If you execute the display interface vlan-interface command, the Last 300 seconds input rate or Last 300 seconds output rate field in the command output displays the average outbound or inbound traffic rate in the last 300 seconds.
By default, traffic rate = native frame length × packet count per second. Execute the traffic-statistic include-interframe command if you need the total traffic statistics, including the native frame length, interframe gap length, and preamble length, for a specific time period. With this command executed, traffic rate = (native frame length + interframe gap length + preamble length) × packet throughput per second.
Examples
# Enable interframe gap and preamble statistics in the traffic statistics for VLAN-interface 10.
<Sysname> system-view

Parameters
vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN ID or a range of VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. The value for the vlan-id2 argument must be equal to or greater than the value for the vlan-id1 argument.
all: Specifies all VLANs. To prevent unauthorized VLAN users from accessing restricted resources through the port, use the port trunk permit vlan all command with caution.
Usage guidelines
A trunk port can allow multiple VLANs. If you execute this command multiple times on a trunk port, the trunk port allows all the specified VLANs.
On a trunk port, packets only from the PVID can pass through untagged.
Examples
# Configure Ten-GigabitEthernet 3/1/1 as a trunk port, and assign it to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100.

Parameters
vlan-id: Specifies a VLAN by its ID in the range of 1 to 4094.
Usage guidelines
You can use a nonexistent VLAN as the PVID for a trunk port. When you delete the PVID of a trunk port by using the undo vlan command, the PVID setting of the port does not change.
For correct packet transmission, set the same PVID for a local trunk port and its peer.
To enable a trunk port to transmit packets from its PVID, you must assign the trunk port to the PVID by using the port trunk permit vlan command.
Examples
# Configure Ten-GigabitEthernet 3/1/1 as a trunk, set its PVID to VLAN 100, and assign it to VLAN 100.

Route interface |
Whether a VLAN interface is configured for the VLAN. |
|
IPv4 address |
Primary IPv4 address of the VLAN interface. This field is displayed only when an IPv4 address is configured for the VLAN interface. When the VLAN interface is also configured with secondary IPv4 addresses, you can view them by using one of the following commands: · display interface vlan-interface. · display this (VLAN interface view). |
|
IPv4 subnet mask |
Subnet mask for the primary IPv4 address of the VLAN interface. This field is displayed only when an IPv4 address is configured for the VLAN interface. |
|
IPv6 global unicast addresses |
Global unicast IPv6 address of the VLAN interface. This field is not displayed when no IPv6 address is configured for the VLAN interface. The IPv6 address states are as follows: · TENTATIVE—Initial state. DAD is being performed or is to be performed on the address. An address in this state cannot be used as the source address or destination address of packets. · DUPLICATE—DAD has been completed for the address. The address is not unique on the link and cannot be used. · PREFERRED—The address is preferred and can be used as the source or destination address of a packet. If an address is in this state, the command does not display the address state. · DEPRECATED—The address is beyond the preferred lifetime but within the valid lifetime. It is valid, but it cannot be used as the source address for a new connection. Packets destined to the address are processed correctly. |

Syntax
subvlan vlan-id-list
undo subvlan [ vlan-id-list ]
Default
A super VLAN is not associated with any sub-VLANs.
Views
VLAN view
Predefined user roles
network-admin
Parameters
vlan-id-list: Specifies a space-separated list of up to 10 sub-VLAN items. Each item specifies a sub-VLAN ID or a range of sub-VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for sub-VLAN IDs is 1 to 4094. The value for the vlan-id2 argument must be equal to or greater than the value for the vlan-id1 argument.
Usage guidelines
Make sure sub-VLANs already exist before you associate them with a super VLAN.
You can add ports to and remove ports from a sub-VLAN that is already associated with a super VLAN.
When you use the undo subvlan command, follow these guidelines:
· If you do not specify the vlan-id-list argument, this command dissociates all sub-VLANs from the current super VLAN.
· If you specify the vlan-id-list argument, this command dissociates the specified sub-VLANs from the current super VLAN.
Examples
# Associate super VLAN 10 with sub-VLANs 3, 4, and 5.
<Sysname> system-view
[Sysname] vlan 3 to 5
[Sysname] vlan 10
[Sysname-vlan10] supervlan
