CAUTION:

The default command might interrupt ongoing network services. Make sure you are fully aware of the impact 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.

Predefined user roles

network-admin

Parameters

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (In IRF mode.)

Usage guidelines

Specify a traffic processing slot for a VLAN interface if all traffic on the VLAN interface must be processed on the same slot.

For high availability, you can specify one primary and one backup traffic processing slot by using the service command and the service standby command, respectively.

To avoid processing slot switchover, specify the primary slot before specifying the backup slot. If you specify the backup slot before specifying the primary slot, traffic is switched over to the primary slot immediately after you specify the primary slot.

If you specify both primary and backup slots for an interface, traffic on that interface is processed as follows:

· The backup slot takes over when the primary slot becomes unavailable. The backup slot continues to process traffic for the interface after the primary slot becomes available again. The switchover will not occur until the backup slot becomes unavailable.

· When no specified traffic processing slots are available, the traffic is processed on the slot at which it arrives. Then, the processing slot that first becomes available again takes over.

If you do not specify a primary or a backup traffic processing slot for an interface, traffic on that interface is processed on the slot at which the traffic arrives.

Examples

# Specify a primary traffic processing slot for VLAN-interface 2.

Default

A VLAN interface is not manually shut down.

Views

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 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.

Parameters

vlan-id1: 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 all VLANs except reserved VLANs. The keyword is not supported when the maximum number of VLANs that can be created on a device is less than 4094.

Usage guidelines

You cannot create or delete the system default VLAN (VLAN 1) or reserved VLANs.

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

Parameters

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 GigabitEthernet 1/0/1 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 GigabitEthernet 1/0/1 as a trunk, set its PVID to VLAN 100, and assign it to VLAN 100.

Parameters

group-name: Specifies a VLAN group by its name, a case-sensitive string of 1 to 31 characters. The first character must be an alphabetical character.

Usage guidelines

A VLAN group includes a set of VLANs. You can add multiple VLAN lists to a VLAN group.

On an authentication server, a VLAN group name represents a group of authorization VLANs. When an 802.1X user passes authentication, the authentication server assigns a VLAN group name to the device. The device then uses the received VLAN group name to match the locally configured VLAN group names. If a match is found, the device selects a VLAN from the group and assigns the VLAN to the user.

Examples

# Create a VLAN group named test001 and enter VLAN group 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.

Usage guidelines

A VLAN cannot be configured as both a super VLAN and a guest VLAN, Auth-Fail VLAN, or critical VLAN. For more information about guest VLANs, Auth-Fail VLANs, and critical VLANs, see Security Configuration Guide.

As a best practice, do not configure VRRP for a super VLAN interface, because the configuration affects network performance.

Layer 2 multicast configuration for super VLANs does not take effect because they do not have physical ports.

Parameters

minutes: Sets the voice VLAN aging timer in the range of 5 to 43200 in minutes.

Usage guidelines

In automatic voice VLAN assignment mode, the device starts an aging timer for a voice VLAN when assigning a port to the voice VLAN. If no voice packets are received on the port before the timer expires, the device removes the port from the voice VLAN.

The aging timer of a voice VLAN starts only when the dynamic MAC address entry of the voice VLAN ages out. The aging period for the voice VLAN equals the sum of the voice VLAN aging timer and the aging timer for its dynamic MAC address entry. For more information about the aging timer for dynamic MAC address entries, see MAC address table configuration in Layer 2—LAN Switching Configuration Guide.

Set the voice VLAN aging timer only when the voice VLAN assignment mode is automatic.

Examples

# Set the voice VLAN aging timer to 100 minutes.

Parameters

mac-address: Specifies a source MAC address of voice traffic, in the format of H-H-H. For example, 1234-1234-1234.

mask oui-mask: Specifies the valid length of the OUI address by using a mask in the format of H-H-H. The mask contains consecutive 1s and 0s. For example, ffff-0000-0000. To match the voice devices of a vendor, set the mask to ffff-ff00-0000.

description text: Specifies the OUI address description, a case-sensitive string of 1 to 30 characters.

oui: Specifies an OUI address to delete, in the format of H-H-H. For example, 1234-1200-0000. An OUI address is the logical AND result of the mac-address and oui-mask arguments. It cannot be a broadcast address, a multicast address, or an all-zero address.

Usage guidelines

You can manually delete or add the system default OUI addresses.

The maximum number of configurable OUI addresses depends on the device model.
