Views

VLAN-interface view

Default command level

2: System level

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 and system restrictions. You can identify these commands by using the display this command in interface view, and then use their undo forms or follow the command reference to individually restore their default settings. If your restoration attempt still fails, follow the error message to resolve the problem.

When you execute this command on VLAN interface 1, the IP address of the interface is deleted and will not be restored to the default address (192.168.0.50).

Examples

# Restore the default settings for VLAN-interface 2.

<Sysname> system-view

[Sysname] interface vlan-interface 2

[Sysname-Vlan-interface2] default

This command will restore the default settings. Continue? [Y/N]:y

description

Use description to change the description of the VLAN or VLAN-interface.

Use undo description to restore the default.

Syntax

description text

undo description

Default

The description for a VLAN is VLAN vlan-id, which is the ID of the VLAN. For example, the default description of VLAN 100 is VLAN 0100. The default description for a VLAN-interface is the name of the interface. For example, the default description of VLAN-interface 1 is Vlan-interface1 Interface.

Views

VLAN view, VLAN-interface view

Default command level

2: System level

Parameters

text: Specifies a description for a VLAN or VLAN-interface. The string can include case-sensitive letters, digits, special characters such as tilde (~), exclamation point (!), at sign (@), pound sign (#), dollar sign ($), percent sign (%), caret (^), ampersand sign (&), asterisk (*), left brace({), right brace (}), left parenthesis ((), right parenthesis ()), left bracket ([), right bracket (]), left angle bracket (<), right angle bracket (>), hyphen (-), underscore(_), plus sign (+), equal sign (=), vertical bar (|), back slash (\), colon (:), semi-colon (;) quotation marks ("), apostrophe ('), comma (,), dot (.), and slash (/), spaces, and other Unicode characters and symbols.

· For a VLAN, this is a string of 1 to 32 characters.

· For a VLAN-interface, this is a string of 1 to 80 characters.

When you specify a description, follow these guidelines:

· Each Unicode character takes the space of two regular characters.

· To use Unicode characters or symbols in an interface description, install the specific input method editor and log in to the device through remote login software that supports the character type.

· When the length of a description string reaches or exceeds the maximum line width on the terminal software, the software starts a new line, possibly breaking a Unicode character into two and creating garbled characters at the end of a line.

Usage guidelines

Configure a description to describe the function or connection of a VLAN or VLAN-interface for easy management.

Examples

# Change the description of VLAN 2 to sales-private.

<Sysname> system-view

[Sysname] vlan 2

[Sysname-vlan2] description sales-private

# Change the description of VLAN-interface 2 to linktoPC56.

<Sysname> system-view

The string can include case-sensitive letters, digits, special characters such as tilde (~), exclamation point (!), at sign (@), pound sign (#), dollar sign ($), percent sign (%), caret (^), ampersand sign (&), asterisk (*), left brace({), right brace (}), left parenthesis ((), right parenthesis ()), left bracket ([), right bracket (]), left angle bracket (<), right angle bracket (>), hyphen (-), underscore(_), plus sign (+), equal sign (=), vertical bar (|), back slash (\), colon (:), semi-colon (;) quotation marks ("), apostrophe ('), comma (,), dot (.), and slash (/), spaces, and other Unicode characters and symbols.

Usage guidelines

When 802.1X or MAC address authentication is configured on the device, you can use a RADIUS server to issue VLAN configuration to ports that have passed the authentication. Some servers can send IDs or names of the issued VLANs to the device.

Use VLAN names, rather than VLAN IDs, to distinguish a large number of VLANs.

Examples

# Configure the name of VLAN 2 as Test VLAN.

<Sysname> system-view

[Sysname] vlan 2

[Sysname-vlan2] name Test VLAN

Related commands

Views

User view

Default command level

2: System level

Parameters

vlan-interface-id: Specifies a VLAN-interface number.

Usage guidelines

Before collecting the traffic statistics within a specific period of time on an interface, clear the existing statistics first.

If the vlan-interface-id argument is not specified, this command clears the statistics of all VLAN-interfaces.

If the vlan-interface-id argument is specified, this command clears the statistics of the specified VLAN-interface.

Examples

# Clear the statistics on VLAN-interface 2.

<Sysname> reset counters interface vlan-interface 2

Related commands

display interface vlan-interface

shutdown

Use shutdown to manually shut down a VLAN-interface.

Use undo shutdown to cancel the action of shutting down a VLAN-interface.

Syntax

shutdown

undo shutdown

Default

A VLAN-interface is not manually shut down. The VLAN-interface is up if one or more ports in the VLAN is up, and goes down if all ports in the VLAN go down.

Views

VLAN-interface view

Default command level

2: System level

Usage guidelines

A VLAN-interface shut down with the shutdown command is in DOWN (Administratively) state until you bring it up, regardless of how the state of the ports in the VLAN changes.

Before configuring parameters for a VLAN-interface, shut down the VLAN-interface with the shutdown command to prevent the configurations from affecting the network. Use the undo shutdown command to bring up a VLAN-interface after you have configured related parameters and protocols for the VLAN-interface.

You can shut down a failed interface with the shutdown command and then bring it up with the undo shutdown command to see if it recovers.

In a VLAN, the state of any Ethernet port is independent of the state of the VLAN-interface.

Examples

# Shut down VLAN-interface 2, and then cancel the action of shutting it down.

<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 enter the view of an existing VLAN.

Use vlan vlan-id1 to vlan-id2 to create VLANs ranging from vlan-id1 to vlan-id2, except reserved VLANs.

Use undo vlan to remove the specified VLANs.

Syntax

vlan { vlan-id1 [ to vlan-id2 ] }

undo vlan { vlan-id1 [ to vlan-id2 ] | all }

Default

Only the default VLAN (VLAN 1) exists in the system.

Views

System view

Default command level

2: System level

Parameters

vlan-id1, vlan-id2: Specifies a VLAN ID, ranging from 1 to 4094.

vlan-id1 to vlan-id2: Specifies a VLAN range. vlan-id2 must be no smaller than vlan-id1.

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 remove the default VLAN (VLAN 1).

You cannot create or remove VLANs reserved for specific functions.

To remove the following VLANs, remove the related configurations first, because you cannot use the undo vlan command to directly remove them:

· Protocol reserved VLANs

· Management VLANs

· Dynamic VLANs

· VLANs configured with QoS policies

Examples

# Create VLAN 2, and enter VLAN 2 view.

<Sysname> system-view

[Sysname] vlan 2

[Sysname-vlan2]

# Create VLAN 4 through VLAN 100.

<Sysname> system-view

[Sysname] vlan 4 to 100

The configuration made in Ethernet or WLAN-BSS interface view applies only to the port.

The configuration made in Layer 2 aggregate interface view applies to the aggregate interface and its aggregation member ports.

· If the system fails to apply the configuration to the aggregate interface, it stops applying the configuration to aggregation member ports.

· If the system fails to apply the configuration to an aggregation member port, it skips the port and moves to the next member port.

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

# Configure Layer 2 aggregate interface Bridge-Aggregation 1 and its member ports as hybrid ports.

port trunk permit vlan

Use port trunk permit vlan to assign the trunk ports to the specified VLANs.

Use undo port trunk permit vlan to remove the trunk ports from the specified VLANs.

Syntax

port trunk permit vlan { vlan-list | all }

undo port trunk permit vlan { vlan-list | all }

Default

A trunk port allows only packets from VLAN 1 to pass through.

Views

Ethernet interface view, Layer 2 aggregate interface view

Default command level

2: System level

Parameters

vlan-list: Specifies a list of VLANs that the trunk ports will be assigned to in the format of { vlan-id1 [ to vlan-id2 ] }&<1-10>, where vlan-id1 and vlan-id2 represent VLAN IDs and each range from 1 to 4094, vlan-id2 must be no smaller than vlan-id1, and &<1-10> indicates that you can specify up to 10 VLAN IDs or VLAN ID ranges. Make sure the specified VLANs already exist.

all: Permits all VLANs to pass through the trunk ports.

Usage guidelines

A trunk port can carry multiple VLANs. If you execute the port trunk permit vlan command multiple times, the trunk port carries the set of VLANs specified by vlan-list in each execution.

On a trunk port, only traffic of the PVID can pass through untagged.

To prevent unauthorized VLAN users from accessing restricted resources, use the port trunk permit vlan all command with caution.

The configuration made in Ethernet interface view applies only to the port.

The configuration made in Layer 2 aggregate interface view applies to the aggregate interface and its aggregation member ports.

· If the system fails to apply the configuration to the aggregate interface, it stops applying the configuration to aggregation member ports.

· If the system fails to apply the configuration to an aggregation member port, it skips the port and moves to the next member port.

Examples

# Assign the trunk port GigabitEthernet 1/0/1 to VLAN 2, VLAN 4, and VLAN 50 through VLAN 100.

<Sysname> system-view

[Sysname] interface GigabitEthernet 1/0/1

[Sysname-GigabitEthernet1/0/1] port link-type trunk

[Sysname-GigabitEthernet1/0/1] port trunk permit vlan 2 4 50 to 100

port trunk pvid

Use port trunk pvid to configure the PVID for the trunk port.

Use undo port trunk pvid to restore the default.

Syntax

port trunk pvid vlan vlan-id

undo port trunk pvid

Default

The PVID of a trunk port is VLAN 1.

Views

Ethernet interface view, Layer 2 aggregate interface view

Default command level

2: System level

Parameters

vlan-id: Specifies a VLAN ID, ranging from 1 to 4094.

Usage guidelines

You can use a nonexistent VLAN as the PVID for a trunk port. If you use the undo vlan command to remove the PVID of a trunk port, it does not affect the setting of the PVID on the port.

The local and remote trunk ports must use the same PVID for the traffic of the PVID to be transmitted properly.

You must use the port trunk permit vlan command to configure the trunk port to allow and forward packets from the PVID.

The configuration made in Ethernet interface view applies only to the port.

The configuration made in Layer 2 aggregate interface view applies to the aggregate interface and its aggregation member ports.

· If the system fails to apply the configuration to the aggregate interface, it stops applying the configuration to aggregation member ports.

· If the system fails to apply the configuration to an aggregation member port, it skips the port and moves to the next member port.

Parameters

mac-address mac-address: Specifies a MAC address.

mask mac-mask: Specifies a mask for the MAC address in the format of H-H-H. 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 all Fs in hexadecimal notation.

vlan vlan-id: Specifies a VLAN ID, ranging from of 1 to 4094.

priority pri: Specifies the 802.1p priority value corresponding to the specified MAC address. The pri argument ranges from 0 to 7.

all: Removes all the static MAC address-to-VLAN entries.

Usage guidelines

Two MAC address-to-VLAN entry tables exist in a device. One table contains the MAC address-to-VLAN entries configured with the mask keyword specified. A MAC address-to-VLAN entry of this type describes the relationship between a group of MAC addresses and a VLAN, and a priority value. Another table contains the MAC address-to-VLAN entries configured without the mask keyword specified. A MAC address-to-VLAN entry of this type describes the relationship between a single MAC address and a VLAN, and a priority value. The system adds or removes MAC address-to-VLAN entries to or from the two tables according to the configuration.

Examples

# Associate a single MAC address 0-1-1 with VLAN 100 and 802.1p priority 7.

<Sysname> system-view

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

# Associate the MAC addresses with the high-order six hexadecimal digits being 121122 with VLAN 100 and 802.1p priority 4.

<Sysname> system-view

[Sysname] mac-vlan mac-address 1211-2222-3333 mask ffff-ff00-0000 vlan 100 priority 4
