VLAN commands
Basic VLAN commands
bandwidth
Use bandwidth to set the expected bandwidth of an interface.
Use undo bandwidth to restore the default.
Syntax
bandwidth bandwidth-value
undo bandwidth
Default
The expected bandwidth (in kbps) is the interface baud rate divided by 1000.

network-admin
Parameters
bandwidth-value: Specifies the expected bandwidth in the range of 1 to 400000000 kbps.
Usage guidelines
The expected bandwidth is an informational parameter used only by higher-layer protocols for calculation. You cannot adjust the actual bandwidth of an interface by using this command.
Examples
# Set the expected bandwidth to 10000 kbps for VLAN-interface 1.
<Sysname> system-view
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface1] bandwidth 10000
default
Use default to restore the default settings for a VLAN interface.
Syntax

CAUTION: The default command might interrupt ongoing network services. Make sure you are fully aware of the impacts of this command when you use it on a live network. |
This command might fail to restore the default settings for some commands for reasons such as command dependencies or system restrictions. Use the display this command in interface view to identify these commands, and then use their undo forms or follow the command reference to restore their default settings. If your restoration attempt still fails, follow the error message instructions to resolve the problem.
Examples
# Restore the default settings for VLAN-interface 1.
<Sysname> system-view
[Sysname] interface vlan-interface 1
[Sysname-Vlan-interface1] default
description
Use description to set the description for a VLAN or VLAN interface.
Use undo description to restore the default.
Syntax
description text
undo description
Default
For a VLAN, the description 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 default description of VLAN 100 is VLAN 0100.
For a VLAN interface, the description is the name of the interface. For example, Vlan-interface1 Interface.

Usage guidelines
You can configure a description to describe the function or connection of a VLAN or VLAN interface. The descriptions are helpful when a large number of VLANs and VLAN interfaces are created on the device.
Examples
# Set the description of VLAN 2 to sales-private.
<Sysname> system-view
[Sysname] vlan 2
[Sysname-vlan2] description sales-private
# Set the description of VLAN-interface 2 to linktoPC56.
<Sysname> system-view

Use undo shutdown to bring up a VLAN interface.
Syntax
shutdown
undo shutdown
Default
A VLAN interface is not manually shut down.
Views
VLAN interface view
Predefined user roles
network-admin
Usage guidelines
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 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
vlan
Use vlan vlan-id to create a VLAN and enter its view or to enter the view of an existing VLAN.
Use vlan vlan-id1 to vlan-id2 to create VLANs vlan-id1 through vlan-id2.
Use vlan all to create VLANs 1 through 4094.
Use undo vlan to delete the specified VLANs.
Syntax
vlan { vlan-id1 [ to vlan-id2 ] | all }
undo vlan { vlan-id1 [ to vlan-id2 ] | all }
Default
VLAN 1 (system default VLAN) exists.

Predefined user roles
network-admin
Parameters
vlan-id1, vlan-id2: Specifies a VLAN ID in the range of 1 to 4094.
vlan-id1 to vlan-id2: Specifies a VLAN range. The vlan-id1 and vlan-id2 arguments specify VLAN IDs. The value range for each of the two arguments 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 VLANs1 through 4094.
Usage guidelines
You cannot create or delete the system default VLAN (VLAN 1).
Before you delete a dynamic VLAN or a VLAN locked by an application, you must first remove the configuration from the VLAN.
Examples
# Create VLAN 2 and enter its view.
<Sysname> system-view
[Sysname] vlan 2
[Sysname-vlan2]
# Create VLANs 4 through 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 of a hybrid port. When you delete the PVID of a hybrid 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 hybrid port and its peer.
To enable a hybrid port to transmit packets from its PVID, you must assign the hybrid port to the PVID by using the port hybrid vlan command.
Examples
# Set the PVID of the hybrid port GigabitEthernet 1/0/1 to VLAN 100, and assign GigabitEthernet 1/0/1 to VLAN 100 as an untagged member.

tagged: Configures the port as a tagged member of the specified VLANs. A tagged member of a VLAN sends packets from the VLAN without removing VLAN tags.
untagged: Configures the port as an untagged member of the specified VLANs. An untagged member of a VLAN sends packets from the VLAN after removing VLAN tags.
Usage guidelines
A hybrid port can allow multiple VLANs. If you execute this command multiple times on a hybrid port, the hybrid port allows the VLANs specified by the vlan-id-list argument in each execution.
Examples
# Configure GigabitEthernet 1/0/1 as a hybrid port, and assign it to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100 as a tagged member.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] port link-type hybrid
[Sysname-GigabitEthernet1/0/1] port hybrid vlan 2 4 50 to 100 tagged

Parameters
access: Sets the port link type to access.
hybrid: Sets the port link type to hybrid.
trunk: Sets the port link type to trunk.
Usage guidelines
To change the link type of a port from trunk to hybrid or vice versa, first set the link type to access.
Examples
# Configure GigabitEthernet 1/0/1 as a trunk port.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] port link-type trunk
port trunk permit vlan
Use port trunk permit vlan to assign a trunk port to the specified VLANs.
Use undo port trunk permit vlan to remove a trunk port from the specified VLANs.
Syntax
port trunk permit vlan { vlan-id-list | all }
undo port trunk permit vlan { vlan-id-list | all }
Default
A trunk port allows packets only from VLAN 1 to pass through.

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 a 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 the VLANs specified by the vlan-id-list argument in each execution.
On a trunk port, packets only from the PVID can pass through untagged.
Examples
# Configure GigabitEthernet 1/0/1 as a trunk port, and assign it to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1

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
# Set the PVID of the trunk port GigabitEthernet 1/0/1 to VLAN 100, and assign GigabitEthernet 1/0/1 to VLAN 100.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
