Predefined user roles

network-admin

mdc-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, except reserved VLANs.

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 }

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 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

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.

mdc-admin

Parameters

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 all Fs in hexadecimal notation.

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 specify the 802.1p priority as 7 for VLAN 100 in this entry.

# Associate VLAN 100 with MAC addresses whose six high-order bits are 121122, and specify the 802.1p priority as 4 for VLAN 100 in this entry.

Views

VLAN view

Predefined user roles

at: Specifies the AppleTalk-based VLAN.

mdc-admin

Parameters

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 0x0600 to 0xFFFF, excluding 0x0800, 0x809B, 0x8137, and 0x86DD.

llc: Matches the LLC encapsulation format.

dsap dsap-id: Specifies the destination service access point in the range of 0x00 to 0xFF.

ssap ssap-id: Specifies the source service access point in the range of 0x00 to 0xFF.

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 0x0600 to 0xFFFF, excluding 0x8137.

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 configure the following values for the etype-id argument in the ethernetii etype etype-id option:

¡ 0x0800—Specifies the IPv4 protocol in Ethernet II encapsulation.

¡ 0x809B—Specifies the AppleTalk protocol in Ethernet II encapsulation.

¡ 0x8137—Specifies the IPX protocol in Ethernet II encapsulation.

¡ 0x86DD—Specifies the IPv6 protocol in Ethernet II encapsulation.

These values conflict with the ipv4, at, ipx, and ipv6 keywords of the command, respectively.

· Do not configure any of the following values for both the dsap-id and ssap-id arguments when you specify the llc keyword:

¡ 0xE0—Specifies the 802.2 LLC encapsulation format for IPX packets.

¡ 0xFF—Specifies the 802.3 raw encapsulation format for IPX packets.

¡ 0xAA—Specifies the 802.2 SNAP encapsulation format.

When either of the dsap-id and ssap-id arguments is configured, the system assigns 0xAA to the other argument.

· Do not set the etype-id argument in the snap etype etype-id option to 0x8137. Otherwise, the template format will be the same as that of the IPX protocol. You can set the etype-id argument to 0x0800, 0x809B, or 0x86DD, which correspond to IPv4, AppleTalk, and IPv6, respectively.

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 associating 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.

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 tasks:

¡ Changes the port link type to hybrid.

¡ Configures the secondary VLAN as the PVID.

¡ 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.

¡ If the hybrid port has been a tagged or untagged member of the primary VLAN, this member attribute remains in the primary VLAN.

¡ 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 that 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 tasks:

¡ Changes the port link type to hybrid.

¡ Configures the primary VLAN as the PVID.

¡ Assign 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.

¡ 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.

¡ 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 tasks:

¡ Changes the port link type to hybrid. The PVID of the port does not change.

¡ 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.

¡ 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.

¡ 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 tasks:

¡ Changes the port link type to hybrid. The PVID of the port does not change.

¡ 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.

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

¡ 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.

¡ 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 separately associated with multiple 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 that are 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

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

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

Typically, an OUI address refers to the first 24 bits of a MAC address (in binary notation) and is a globally unique identifier that IEEE assigns to a vendor.
