Parameters

vlan-id: ID of the VLAN interface, in the range of 1 to 4,094.

Description

Use the interface vlan-interface command to create a VLAN interface and enter VLAN interface view.

Use the undo interface vlan-interface command to delete the VLAN interface.

Related commands: display interface vlan-interface.

l Before you can create a VLAN interface, you must create the corresponding VLAN.

l You can configure a maximum number of eight VLAN interfaces on the device.

Parameters

text: VLAN name, in the range of 1 character to 32 characters. It can contain special characters and spaces.

Description

Use the name command to assign a name to the current VLAN.

Use the undo name command to restore to the default VLAN name.

By default, the name of a VLAN is its VLAN ID, such as “VLAN 0001”.

Examples

# Specify the name of VLAN 2 as ”test vlan”.

shutdown

Syntax

shutdown

undo shutdown

View

VLAN interface view

Parameters

None

Description

Use the shutdown command to disable the VLAN interface.

Use the undo shutdown command to enable the VLAN interface.

By default, the VLAN interface is enabled. In this case, the physical status of the VLAN interface is affected by that of the ports in the VLAN.

l When all the Ethernet ports in the VLAN are down, the VLAN interface of the VLAN is down, that is, the VLAN interface is disabled.

l When one or more Ethernet ports in the VLAN are up, the VLAN interface of the VLAN is up, that is, the VLAN interface is enabled.

If you disable the VLAN interface, the status of the VLAN interface will always be down, regardless of the status of the ports in the VLAN.

You can use the undo shutdown command to enable a VLAN interface when its related parameters and protocols are configured. When a VLAN interface fails, you can use the shutdown command to disable the interface, and then use the undo shutdown command to enable this interface again, which may restore the interface.

The operation of enabling/disabling a VLAN interface does not influence the status of the Ethernet ports belonging to this VLAN.

Parameters

vlan-id: ID of the VLAN which you want to create and whose view you want to enter. This argument ranges from 1 to 4,094.

Description

Use the vlan command to enter VLAN view. If the VLAN identified by the vlan-id argument does not exist, this command creates the VLAN and then enters VLAN view.

Use the undo vlan command to remove the specified VLAN.

l VLAN 1 is the default VLAN and cannot be removed.

l When you use the undo vlan command to remove a VLAN which is the default VLAN of a trunk port or a hybrid port on the device, the configuration of the default VLAN of the trunk port or hybrid port does not change after the undo vlan command is executed, that is, the trunk port or the hybrid port will use the removed VLAN (the already non-existing VLAN) as its default VLAN.

l The VLANs kept by protocol , voice VLAN, management VLAN and the probe VLAN for remote mirroring cannot be removed using the undo vlan command.

Examples

# Enter VLAN 1 view.

Parameters

interface-list: List of Ethernet ports to be added to or removed from a VLAN. You need to provide this argument in the form of interface-list = { interface-type interface-number [ to interface-type interface-number ] } &<1-10>, where:

l interface-type is port type and interface-number is port number.

l The port number to the right of the to keyword must be larger than or equal to the one to the left of the keyword.

Parameters

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

protocol-index: Beginning protocol index in the range of 0 to 7.

to: Specifies multiple contiguous protocol indexes.

protocol-index-end: End protocol index in the range of 0 to 7. Note that this argument must be larger than or equal to the protocol-index argument.

all: Specifies all protocol indexes. If the all keyword in the port hybrid protocol-vlan vlan command is specified, this command associates the port with all the protocol indexes of the specified protocol-based VLAN; if the all keyword in the undo port hybrid protocol-vlan vlan command is specified, the command removes the associations between the port and all the protocol indexes of the specified protocol-based VLAN.

Description

Use the port hybrid protocol-vlan vlan command to associate the port with the specified protocol-based VLAN.

Use the undo port hybrid protocol-vlan vlan command to remove the association between the specified protocol-based VLAN and the port.

l The port hybrid protocol-vlan vlan command can be executed on hybrid ports only.

l Before you associate a port with the protocol-based VLAN, make sure the port belongs to the protocol-based VLAN.

l When the undo port hybrid protocol-vlan vlan command is being executed, the device will prompt operation failure if the index of the specified protocol to be removed does not exist. If a part of the specified protocol indexes to be removed do not exist, the device will remove the existing indexes when it prompts errors.

Related commands: display protocol-vlan interface.

undo protocol-vlan { protocol-index [ to protocol-index-end ] | all }

View

VLAN view

Parameters

at: Specifies the VLAN to be an AppleTalk-based VLAN.

ip: Specifies the VLAN to be an IP-based VLAN.

ipx: Specifies the VLAN to be an IPX-based VLAN. The ethernetii, llc, raw and snap keywords specify the four IPX encapsulation types.

mode: Configures user-defined protocol templates.

ethernetii etype-id: Matches the Ethernet II encapsulation format and the corresponding protocol type value of the packet. The etype-id argument ranges from 0x0600 to 0xFFFF.

llc: Matches LLC encapsulation format.

dsap-id: Destination service access point. This argument ranges 0x0000 to 0x00FF.

ssap-id: Source service access point. This argument ranges from 0x0000 to 0x00FF.

snap etype-id: Matches SNAP encapsulation format and the corresponding protocol type value of the packet. The etype-id argument ranges from 0x0600 to 0xFFFF.

protocol-index: Beginning protocol index ranging from 0 to 7. Note that this argument must be less than or equal to the protocol-end argument. If you do not specify this argument, the beginning protocol index will be determined by the system.

protocol-index-end: End protocol index ranging from 0 to 7. Note that this argument must be larger than or equal to the protocol-index argument.

all: Specifies all the protocol indexes.

When you use the mode keyword to configure a user-defined protocol template, if you set the etype-id argument for Ethernet II or SNAP packets to 0x0800, 0x089B, or 0x8137, the matching packets have the same format as that of IP, IPX, and AppleTalk packets respectively. To prevent two commands from processing packets of the same protocol type in different ways, the device will prompt that you cannot set the etype-id argument for Ethernet II or SNAP packets to 0x0800, 0x089B, or 0x8137.

Description

Use the protocol-vlan command to configure the protocol template used for classifying protocol-based VLANs.

Use the undo protocol-vlan command to disable the configuration.

Related commands: display protocol-vlan vlan.

Examples

# Configure VLAN 3 as a protocol-based VLAN and assign IP packets to VLAN 3 for transmission.

<device> system-view

System View: return to User View with Ctrl+Z.

[device] vlan 3

[device-vlan3] protocol-vlan ip

Because the IP protocol is closely associated with the ARP protocol, you are recommended to configure the ARP protocol type when configuring the IP protocol type and associate the two protocol types with the same port, in case that ARP packets and IP packets are not assigned to the same VLAN, which will cause IP address resolution failure.

# Configure an ARP protocol template. The code for the ARP protocol is 0x0806.

l Perform the following command when Ethernet encapsulation is used.

[device-vlan3] protocol-vlan mode ethernetii etype 0806

l Perform the following configuration when 802.3 encapsulation format is used.

[device-vlan3] protocol-vlan mode snap etype 0806
