Usage guidelines

| 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.

<Sysname> system-view

[Sysname] interface vlan-interface 1

[Sysname-Vlan-interface1] default

VLAN commands -- Basic VLAN commands -- description

Use description to configure the description of 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.

Parameters

vlan-interface-id1: Specifies a VLAN by its ID in the range of 1 to 4094.

vlan-interface-id1 to vlan-interface-id2: Specifies a range of VLAN IDs. The value ranges for the vlan-interface-id1 and vlan-interface-id2 arguments are both 1 to 4094. The value for the vlan-interface-id2 argument must be greater or equal to the value for the vlan-interface-id1 argument.

global: Specifies global VLAN interface resources. If you do not specify this keyword, the command reserves local VLAN interface resources.

Usage guidelines

The VLAN interface resource reservation of a VLAN conflicts with the VLAN creation. Select the unused VLANs for resource reservation.

As a best practice to simplify management and configuration, reserve VLAN interface resources as follows:

· Bulk reserve resources of VLAN interfaces that are numbered in consecutive order.

· Preferentially reserve resources of VLAN interfaces numbered in the range of 3000 to 3500.

Before creating a Layer 3 Ethernet subinterface or aggregate subinterface, do not reserve a resource for the VLAN interface whose interface number matches the subinterface number. After you reserve a VLAN interface resource, do not create a Layer 3 Ethernet subinterface or aggregate subinterface whose subinterface number is the VLAN interface number. A Layer 3 Ethernet subinterface or aggregate subinterface uses the VLAN interface resource for processing tagged packets whose VLAN ID matches the subinterface number.

A reserved VLAN interface resource can only be of the local or global type. To change the type of a reserved VLAN interface resource, first remove the reservation. You cannot remove the reservation of a VLAN interface resource if this resource has been used.

After the software upgrades to support this feature, first reserve VLAN interface resources for existing configurations that require the reservation.

Examples

# Reserve the local resource of VLAN-interface 3000.

<Sysname> system-view

[Sysname] reserve-vlan-interface 3000

# Reserve local resources of VLAN-interfaces 3000 through 3400.

<Sysname> system-view

[Sysname] reserve-vlan-interface 3000 to 3400

# Reserve global resources of VLAN-interfaces 3400 through 3500.

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

When you need to examine or troubleshoot the network, you can enable packet statistics for a VLAN to monitor the total number of packets in the VLAN. The VLAN packet statistics include statistics on unicast, multicast, and broadcast packets.

Disable packet statistics for a VLAN to save system resources when you do not need this feature.

After packet statistics is enabled for a VLAN, you can use the display vlan statistics command to display the packet statistics for the VLAN.

The system does not automatically clear the packet statistics for VLANs. To clear the packet statistics for a VLAN, use the reset vlan statistics command.

Examples

# Enable packet statistics for VLAN 2.

<Sysname> system-view

[Sysname] vlan 2

[Sysname-vlan2] statistics enable

Parameters

mac-address mac-address: Specifies a MAC address in the format of H-H-H. The MAC address cannot be a multicast MAC address or all 0s. When you configure a MAC address, leading zeros in each H section can be omitted. For example, to configure a MAC address 000f-00e2-0001, you can enter only f-e2-1.

mask mac-mask: Specifies the MAC address mask. For the mac-mask argument, the high-order bits must be consecutive 1s in binary notation or consecutive Fs in hexadecimal notation. The default value is ffff-ffff-ffff.

vlan vlan-id: Specifies a VLAN ID in the range of 1 to 4094.

dot1q priority: Specifies the 802.1p priority of the VLAN specific to the MAC-to-VLAN entry. The value range for the priority argument is 0 to 7, and the default value is 0. The higher the value, the higher the 802.1p priority.

all: Specifies all static MAC-to-VLAN entries.

Usage guidelines

For successful dynamic MAC-based VLAN assignment, use static VLANs when you create MAC-to-VLAN entries.

Different types of MAC-to-VLAN entries are created depending on whether you specify the mask keyword.

· When you specify this keyword, the created MAC-to-VLAN entry describes the relationship among a group of MAC addresses, a VLAN, and the 802.1p priority for the VLAN.

· When you do not specify this keyword, the created MAC-to-VLAN entry describes the relationship among a MAC address, a VLAN, and the 802.1p priority for the VLAN.

These different types of MAC-to-VLAN entries are stored separately in two tables. The system updates the two tables according to the configuration.

Examples

# Associate the MAC address 0000-0001-0001 with VLAN 100, and set the 802.1p priority to 7 for VLAN 100 in this entry.

<Sysname> system-view

[Sysname] mac-vlan mac-address 0-1-1 vlan 100 dot1q 7

Parameters

at: Specifies the AppleTalk-based VLAN.

ipv4: Specifies the IPv4-based VLAN.

ipv6: Specifies the IPv6-based VLAN.

ipx: Specifies the IPX-based VLAN. The keywords ethernetii, llc, raw, and snap specify IPX encapsulation formats.

mode: Configures a user-defined protocol template for the VLAN. The keywords ethernetii, llc, and snap specify the available encapsulation formats.

ethernetii etype etype-id: Matches the Ethernet II encapsulation format and the specified protocol type ID. The etype-id argument specifies the protocol type ID of inbound packets, in the range of 600 to ffff in hexadecimal notation, excluding 800, 86dd, 809b, and 8137.

llc: Matches the LLC encapsulation format.

dsap dsap-id: Specifies the destination service access point in hexadecimal notation, in the range of 0 to ff.

ssap ssap-id: Specifies the source service access point in hexadecimal notation, in the range of 0 to ff.

snap etype etype-id: Matches the SNAP encapsulation format and the specified protocol type value. The etype-id argument specifies the Ethernet type of inbound packets, in the range of 600 to ffff in hexadecimal notation, excluding 8137.

protocol-index: Specifies a protocol template index that is associated with the VLAN. The value range for this argument is 0 to 65535. The system will automatically assign an index if you do not specify this argument.

to protocol-end: Specifies an end protocol template index of a protocol template range, in the range of 0 to 65535. The value for the protocol-end argument must be greater than or equal to the value for the protocol-index argument.

all: Specifies all protocols associated with the VLAN.

Usage guidelines

| CAUTION: IP uses ARP for address resolution in Ethernet. To prevent communication failures, configure the IP and ARP templates in the same VLAN and associate them with the same port.

‌

When you use the mode keyword to configure a protocol template, follow these restrictions and guidelines:

· Do not set the etype-id argument in the ethernetii etype etype-id option to the following hexadecimal values:

?span style='font:7.0pt "Times New Roman"'> 800—Specifies the IPv4 protocol in Ethernet II encapsulation.

?span style='font:7.0pt "Times New Roman"'> 809b—Specifies the AppleTalk protocol in Ethernet II encapsulation.

?span style='font:7.0pt "Times New Roman"'> 8137—Specifies the IPX protocol in Ethernet II encapsulation.

?span style='font:7.0pt "Times New Roman"'> 86dd—Specifies the IPv6 protocol in Ethernet II encapsulation.

· Do not set both the dsap-id and ssap-id arguments to any of the following hexadecimal values:

?span style='font:7.0pt "Times New Roman"'> e0—Specifies the 802.2 LLC encapsulation format for IPX packets.

?span style='font:7.0pt "Times New Roman"'> ff—Specifies the 802.3 raw encapsulation format for IPX packets.

?span style='font:7.0pt "Times New Roman"'> aa—Specifies the 802.2 SNAP encapsulation format.

When either of the dsap-id and ssap-id arguments is configured, the system assigns the hexadecimal value aa to the other argument.

· Do not set the etype-id argument in the snap etype etype-id option to the hexadecimal value 8137. Otherwise, the template format will be the same as that of the IPX protocol. You can set the etype-id argument to the hexadecimal value 800, 809b, or 86dd. The hexadecimal values 800, 809b, and 86dd correspond to IPv4, AppleTalk, and IPv6, respectively.

Examples

# Assign ARP packets in Ethernet II encapsulation and IPv4 packets to VLAN 3 for transmission. (The protocol type ID for ARP is 0806 in hexadecimal notation.)

Usage guidelines

If the port has been assigned to a secondary VLAN, the command assigns the port to the primary VLAN associated with the secondary VLAN. Also, the following events occur:

· For an access port, the device performs the following operations:

?span style='font:7.0pt "Times New Roman"'> Changes the port link type to hybrid.

?span style='font:7.0pt "Times New Roman"'> Configures the secondary VLAN as the PVID.

?span style='font:7.0pt "Times New Roman"'> Assigns the port to the primary VLAN as an untagged member.

· For a trunk port, the device does not change the port link type or PVID.

· For a hybrid port, the device does not change the port link type or PVID.

?span style='font:7.0pt "Times New Roman"'> If the hybrid port has been a tagged or untagged member of the primary VLAN, this member attribute remains in the primary VLAN.

?span style='font:7.0pt "Times New Roman"'> If the hybrid port does not allow the primary VLAN, the device assigns the port to the primary VLAN as an untagged member.

You can assign the port to a secondary VLAN before or after you execute this command.

The undo port private-vlan command does not change the VLAN attributes (allowed VLANs, port link type, and PVID) of the port.

The port private-vlan host command is mutually exclusive with the port private-vlan trunk promiscuous and port private-vlan trunk secondary commands.

Examples

In this example, VLAN 20 is a secondary VLAN and is associated with primary VLAN 2.

# Configure GigabitEthernet 1/0/1 as a host port, and then verify the configuration.

Parameters

vlan-id: Specifies a VLAN ID in the range of 1 to 4094. Though VLAN 1 is in the valid value range, it cannot be configured in the command.

Usage guidelines

If the specified VLAN is a primary VLAN that has been associated with secondary VLANs, the command assigns the port to the associated secondary VLANs. Also, the following events occur:

· For an access port, the device performs the following operations:

?span style='font:7.0pt "Times New Roman"'> Changes the port link type to hybrid.

?span style='font:7.0pt "Times New Roman"'> Configures the primary VLAN as the PVID.

?span style='font:7.0pt "Times New Roman"'> Assigns the port to the primary VLAN and its associated secondary VLANs as an untagged member.

· For a trunk port, the device does not change the port link type or PVID.

· For a hybrid port, the device does not change the port link type or PVID.

?span style='font:7.0pt "Times New Roman"'> If the hybrid port has been a tagged or untagged member of the primary VLAN and part of its associated secondary VLANs, this member attribute remains in these VLANs. The device assigns the hybrid port to the rest of the associated secondary VLANs as an untagged member.

?span style='font:7.0pt "Times New Roman"'> If the hybrid port does not allow any of the primary VLAN and its associated secondary VLANs, the command assigns the port to these VLANs as an untagged member.

If you execute this command on a promiscuous port multiple times, the most recent configuration takes effect.

The undo port private-vlan command does not change the VLAN attributes (allowed secondary VLANs, link type, and PVID) of the port. When you execute the undo port private-vlan command on a promiscuous port of a VLAN, the command removes the port from the VLAN.

You can configure the VLAN as a primary VLAN before or after you execute the port private-vlan promiscuous command.

This command is mutually exclusive with the port private-vlan trunk promiscuous and port private-vlan trunk secondary commands.

Examples

In this example, VLAN 2 is a primary VLAN, and it is associated with secondary VLAN 20.

Parameters

vlan-id-list: Specifies a space-separated list of up to 10 primary VLAN items. Each item specifies a primary VLAN ID or a range of primary VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for primary 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. Though the system default VLAN (VLAN 1) is in the valid value range, it cannot be configured in the command.

Usage guidelines

If the specified VLANs are primary VLANs that have been associated with secondary VLANs, the command assigns the port to the associated secondary VLANs. Also, the following events occur:

· For an access port, the device performs the following operations:

?span style='font:7.0pt "Times New Roman"'> Changes the port link type to hybrid. The PVID of the port does not change.

?span style='font:7.0pt "Times New Roman"'> Assigns the port to the primary VLANs and the associated secondary VLANs as a tagged member.

· For a trunk port, the device does not change the port link type or PVID.

· For a hybrid port, the device does not change the port link type or PVID.

?span style='font:7.0pt "Times New Roman"'> If the hybrid port has been a tagged or untagged member of part of the primary VLANs and their associated secondary VLANs, this member attribute remains in these VLANs. The device assigns the hybrid port to the rest of the primary VLANs and their associated secondary VLANs as a tagged member.

?span style='font:7.0pt "Times New Roman"'> If the hybrid port does not allow any of the primary VLANs and their associated secondary VLANs, the device assigns the port to these VLANs as a tagged member.

The undo form of this command does not change the VLAN attributes (allowed secondary VLANs, port link type, and PVID) of the port.

If you execute the undo form of this command on a trunk promiscuous port, the command removes the port from the VLANs specified by the vlan-id-list argument.

You can configure the specified VLANs as primary VLANs before or after you execute this command.

This command is mutually exclusive with the port private-vlan host, port private-vlan promiscuous and port private-vlan trunk secondary commands.

For an uplink port to permit multiple primary VLANs, use the port private-vlan trunk promiscuous command to assign the port to these VLANs. The port can then transmit packets from these primary VLANs with VLAN tags. For an uplink port to permit only one primary VLAN, use the port private-vlan promiscuous command to assign the port to the VLAN. The port can then transmit packets from the primary VLAN without VLAN tags.

Examples

In this example, VLANs 2 and 3 are primary VLANs. VLAN 2 is associated with secondary VLAN 20. VLAN 3 is associated with secondary VLAN 30.

Parameters

vlan-id-list: Specifies a space-separated list of up to 10 secondary VLAN items. Each item specifies a secondary VLAN ID or a range of secondary VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for secondary 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. Though the system default VLAN (VLAN 1) is in the valid value range, it cannot be configured in the command.

Usage guidelines

If the specified VLANs are secondary VLANs that have been associated with primary VLANs, the command also assigns the port to the associated primary VLANs. Also, the following events occur:

· For an access port, the device performs the following operations:

?span style='font:7.0pt "Times New Roman"'> Changes the port link type to hybrid. The PVID of the port does not change.

?span style='font:7.0pt "Times New Roman"'> Assigns the port to the secondary VLANs and the associated primary VLANs as a tagged member.

· For a trunk port, the device does not change the port link type or PVID.

· For a hybrid port, the device does not change the port link type or PVID.

?span style='font:7.0pt "Times New Roman"'> If the port has been an untagged or tagged member of part of the secondary VLANs and their associated primary VLANs, this member attribute remains in these VLANs. The device assigns the port to the rest of the secondary VLANs and their associated primary VLANs as a tagged member.

?span style='font:7.0pt "Times New Roman"'> If the hybrid port does not allow any of the secondary VLANs and their associated primary VLANs, the device assigns the port to these VLANs as a tagged member.

A trunk secondary port can join only one secondary VLAN among all secondary VLANs associated with a primary VLAN. However, it can join multiple secondary VLANs that are associated with different primary VLANs.

The undo form of this command does not change the VLAN attributes (allowed primary VLANs, port link type, and PVID) of the port.

When you execute the undo form of this command on a trunk secondary port of the VLANs specified by the vlan-id-list argument, one of the following events occurs:

· If the port is an access port, the device does not change the VLAN configuration of the port.

· If the port is a trunk or hybrid port, the device removes the port from the specified VLANs.

You can associate the specified VLANs with their respective primary VLANs before or after you execute this command.

This command does not take effect on the specified VLAN if any of the following conditions applies:

· The specified VLAN does not exist.

· The specified VLAN is not a secondary VLAN and is used for other purposes.

· The specified VLAN shares the same primary VLAN with other secondary VLANs, and the current port has been configured as a trunk secondary port in one of the other secondary VLANs.

This command is mutually exclusive with the port private-vlan host, port private-vlan promiscuous and port private-vlan trunk promiscuous commands.

For a downlink port to permit multiple secondary VLANs associated with different primary VLANs, use the port private-vlan trunk secondary command to assign the port to these secondary VLANs. The port can then transmit packets from these secondary VLANs with VLAN tags. For a downlink port to permit only one secondary VLAN, use the port private-vlan host command to assign the port to the secondary VLAN. The port can then transmit packets from the secondary VLAN without VLAN tags.

Examples

· In this example, VLANs 2 and 3 are primary VLANs. VLAN 2 is associated with secondary VLAN 20. VLAN 3 is associated with secondary VLAN 30.

Parameters

vlan-id-list: Specifies a space-separated list of up to 10 secondary VLAN items. Each item specifies a secondary VLAN ID or a range of secondary VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for secondary 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

This command takes effect only when the following conditions exist:

· This command is executed in VLAN interface view of the primary VLAN interface.

· Secondary VLANs are associated with the primary VLAN.

· No VLAN interfaces are created for secondary VLANs.

· An IP address is assigned to the primary VLAN interface.

· Local proxy ARP or ND is enabled on the primary VLAN interface.

You can create VLAN interfaces for secondary VLANs that are not enabled with Layer 3 communication. If secondary VLANs are enabled with Layer 3 communication, do not create VLAN interfaces for them.

When you execute this command in the same primary VLAN interface view multiple times, all the specified secondary VLANs are interoperable at Layer 3.

When you execute the undo private-vlan command, follow these guidelines:

· If you specify the secondary vlan-id-list option, this command cancels the Layer 3 communication configuration only for the specified secondary VLANs.

· If you do not specify the secondary vlan-id-list option, this command cancels the Layer 3 communication configuration for all secondary VLANs of the primary VLAN.

Examples

This example shows how to meet the following requirements:

· VLAN 4 is a secondary VLAN, and it is associated with primary VLAN 2.

· The uplink port (GigabitEthernet 1/0/2) is a promiscuous port of VLAN 2.

· Downlink ports GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 are host ports of VLANs 3 and 4, respectively.

Parameters

minutes: Sets the voice VLAN aging timer to 0 minutes or a value in the range of 5 to 43200 minutes. If you set the voice VLAN aging timer to 0 minutes, the voice VLAN does not age out.

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.

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.

<Sysname> system-view

[Sysname] voice-vlan aging 100

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.

Examples

# Add OUI address 1234-1200-0000 by specifying the MAC address as 1234-1234-1234 and the mask as fff-ff00-0000. Configure the OUI address description as PhoneA.
