VLAN view, VLAN interface view
Default Level
2: System level
Parameters
text: Description of a VLAN or VLAN interface. Currently, the device supports the following types of characters or symbols: standard English characters (numbers and case-sensitive letters), special English characters, spaces, and other characters or symbols that conform to the Unicode standard.
l For a VLAN, the description string contains 1 to 32 characters.
l For a VLAN interface, the description string contains 1 to 80 characters.
l A port description can be the mixture of English characters and other Unicode characters. The mixed description cannot exceed the specified length.
l To use a type of Unicode characters or symbols in a port description, you need to install the corresponding Input Method Editor (IME) and log in to the device through remote login software that supports this character type.
l Each Unicode character or symbol (non-English characters) takes the space of two regular characters. 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 parts. As a result, garbled characters may be displayed at the end of a line.
Case-sensitive string that describes the current VLAN or VLAN interface. Spaces can be included in the description.
l For a VLAN, this is a string of 1 to 32 characters.
l For a VLAN interface, this is a string of 1 to 80 characters.
Description
Use the description command to configure the description of the current VLAN or VLAN interface.
Use the undo description command to restore the default.
For a VLAN, the default description is the VLAN ID, for example, VLAN 0001; for a VLAN interface, the default description is the name of the interface, for example, Vlan-interface 1 Interface.
You can configure a description to describe the function or connection of a VLAN or VLAN interface for management sake.

Default Level
2: System level
Parameters
vlan-interface-id: VLAN interface number, in the range of 1 to 4094.
Description
Use the interface vlan-interface command to create a VLAN interface and enter its view or enter the view of an existing VLAN interface.
Before you can create the VLAN interface of a VLAN, create the VLAN first.
Use the undo interface vlan-interface command to remove the specified VLAN interface.
You can use the ip address command in VLAN interface view to configure an IP address for a VLAN interface to perform IP routing.
Related commands: display interface Vlan-interface.
Examples
# Create VLAN-interface 2.
<Sysname> system-view
[Sysname] vlan 2

Syntax
ip address ip-address { mask | mask-length } [ sub ]
undo ip address [ ip-address { mask | mask-length } [ sub ] ]
View
VLAN interface view
Default Level
2: System level
Parameters
ip-address: IP address to be assigned to the current VLAN interface, in dotted decimal format.
mask: Subnet mask in dotted decimal notation.
mask-length: Subnet mask length, the number of consecutive ones in the mask. The value range is 0 to 32.
sub: Indicates the address is a secondary IP address.
Description
Use the ip address command to assign an IP address and subnet mask to a VLAN interface.
Use the undo ip address command to remove the IP address and subnet mask for a VLAN interface.
By default, no IP address is assigned to any VLAN interface.
In general conditions, you need to assign only one IP address for a VLAN interface. For a VLAN to connect to multiple subnets, you need to assign multiple IP addresses for the VLAN interface. Among these IP addresses, one is primary and the others are secondary. On an S5810 switch, you can assign up to ten IP addresses for a VLAN interface.
When configuring IP addresses for a VLAN interface, consider the following:
l You can assign only one primary IP address to an interface.
l Before removing the primary IP address, remove all secondary IP addresses.
l To remove all IP addresses, use the undo ip address command without any parameter.
l To remove the primary IP address, use the undo ip address ip-address { mask | mask-length } command.
l To remove a secondary IP address, use the undo ip address ip-address { mask | mask-length } sub command.
Related commands: display ip interface (IP Address Commands in the IP Services Volume).
Examples
# Specify the IP address as 1.1.0.1, the subnet mask as 255.255.255.0 for VLAN-interface 1.

VLAN view
Default Level
2: System level
Parameters
text: VLAN name, a string of 1 to 32 characters. Spaces and special characters can be included in the name.
Description
Use the name command to configure a name for the current VLAN.
Use the undo name command to restore the default name of the VLAN.
The default name of a VLAN is its VLAN ID, VLAN 0001 for example.
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 switch. When there are a large number of VLANs, you can use VLAN names rather than VLAN IDs to better locate VLANs.
Examples
# Configure the name of VLAN 2 as test vlan.
<Sysname> system-view
[Sysname] vlan 2
[Sysname-vlan2] name test vlan
Syntax
shutdown
undo shutdown
View
VLAN interface view
Default Level
2: System level
Parameters
None
Description
Use the shutdown command to shut down a VLAN interface.
Use the undo shutdown command to bring up a VLAN interface.
By default, a VLAN interface is up except when all ports in the VLAN are down.
You can use the undo shutdown command to bring up a VLAN interface after configuring related parameters and protocols for the VLAN interface. When a VLAN interface fails, you can shut down the interface with the shutdown command and then bring it up with the undo shutdown command. In this way, the interface may resume.
The state of any Ethernet port in a VLAN is independent of the VLAN interface state.
Examples
# Shut down VLAN interface 2 and then bring it up.
<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] shutdown

vlan-id1 to vlan-id2: Specifies a VLAN range. A VLAN ID is in the range 1 to 4094.
all: Creates or removes 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.
Description
Use the vlan vlan-id command to create a VLAN and enter its view or enter the view of an existing VLAN.
Use the vlan vlan-id1 to vlan-id2 command to create a range of VLANs specified by vlan-id1 to vlan-id2, except reserved VLANs.
Use the undo vlan command to remove the specified VLAN(s).
l As the default VLAN, VLAN 1 cannot be created or removed.
l You cannot create/remove reserved VLANs reserved for specific functions.
l You cannot use the undo vlan command to directly remove reserved VLANs, management VLANs, dynamic VLANs, VLANs configured with QoS policies, control VLANs configured for SmartLink, or remote probe VLANs configured for port mirroring. To remove these VLANs, you need to first remove related configurations.

Default Level
2: System level
Parameters
vlan-id: VLAN ID, in the range of 1 to 4094. Be sure that the VLAN specified by the VLAN ID already exists.
Description
Use the port access vlan command to assign the current access port(s) to the specified VLAN.
Use the undo port access vlan command to restore the default.
By default, all access ports belong to VLAN 1.
You can assign an access port to only one VLAN. When doing that, note the following:
l In port group view, this command applies to all ports in the port group. For information about port groups, refer to Ethernet Interface Configuration in the Access Volume.
l In Layer-2 aggregate interface view, this command applies to the Layer-2 aggregate interface and all its member ports. After you perform the configuration, the system starts applying the configuration to the aggregate interface and its aggregation member ports. If the system fails to do that on the aggregate interface, it stops applying the configuration to the aggregation member ports. If it fails to do that on an aggregation member port, it simply skips the port and moves to the next port. For information about Layer-2 aggregate interfaces, refer to Link Aggregation Configuration in the Access Volume.

Parameters
vlan-id: VLAN ID, in the range of 1 to 4094.
Description
Use the port hybrid pvid vlan command to configure the default VLAN ID of the hybrid port.
Use the undo port hybrid pvid command to restore the default.
By default, the default VLAN of a hybrid port is VLAN 1.
You can use a nonexistent VLAN as the default VLAN for a hybrid port. Removing the default VLAN of a hybrid port with the undo vlan command does not affect the setting of the default VLAN on the port.
l In port group view, this command applies to all ports in the port group. For information about port groups, refer to Ethernet Interface Configuration in the Access Volume.
l In Layer-2 aggregate interface view, this command applies to the Layer-2 aggregate interface and all its member ports. After you perform the configuration, the system starts applying the configuration to the aggregate interface and its aggregation member ports. If the system fails to do that on the aggregate interface, it stops applying the configuration to the aggregation member ports. If it fails to do that on an aggregation member port, it simply skips the port and moves to the next port. For information about Layer-2 aggregate interfaces, refer to Link Aggregation Configuration in the Access Volume.
l You are recommended to set the same default VLAN ID for the local and remote hybrid ports.
l After configuring the default VLAN for a hybrid port, you must use the port trunk permit vlan command to configure the hybrid port to allow packets from the default VLAN to pass through, so that the port can forward packets from the default VLAN.
Related commands: port link-type, port hybrid vlan.

View
Ethernet interface view, port group view, Layer-2 aggregate interface view
Default Level
2: System level
Parameters
vlan-id-list: VLANs that the trunk port(s) will be assigned to. This argument is expressed in the format of [vlan-id1 [ to vlan-id2 ] ]&<1-10>, where vlan-id ranges from 1 to 4094 and &<1-10> indicates that you can specify up to 10 VLAN IDs or VLAN ID ranges.
all: Permits all VLANs to pass through the trunk port(s). On GVRP-enabled trunk ports, you must configure the port trunk permit vlan all command to ensure that the traffic of all dynamically registered VLANs can pass through. However, When GVRP is disabled on a port, you are discouraged to configure the command on the port. This is to prevent users of unauthorized VLANs from accessing restricted resources through the port.
Description
Use the port trunk permit vlan command to assign the current trunk port(s) to the specified VLAN(s).
Use the undo port trunk permit vlan command to remove the trunk port(s) from the specified VLANs.
By default, a trunk port allows only packets from VLAN 1 to pass through.
A trunk port can carry multiple VLANs. If you execute the port trunk permit vlan command multiple times, the VLANs the trunk port carries are the set of VLANs specified by vlan-id-list in each execution.
Note that on a trunk port, only traffic of the default VLAN can pass through untagged.
l In port group view, this command applies to all ports in the port group. For information about port groups, refer to Ethernet Interface Configuration in the Access Volume.
l In Layer-2 aggregate interface view, this command applies to the Layer-2 aggregate interface and all its member ports. After you perform the configuration, the system starts applying the configuration to the aggregate interface and its aggregation member ports. If the system fails to do that on the aggregate interface, it stops applying the configuration to the aggregation member ports. If it fails to do that on an aggregation member port, it simply skips the port and moves to the next port. For information about Layer-2 aggregate interfaces, refer to Link Aggregation Configuration in the Access Volume.

This port is not a Trunk port!” indicates that the configuration failed on GigabitEthernet 1/0/2 because GigabitEthernet 1/0/2 was not a trunk port; “Configuring GigabitEthernet 1/0/3... Done” indicates that the configuration on GigabitEthernet 1/0/3 succeeded.
Syntax
port trunk pvid vlan vlan-id
undo port trunk pvid
View
Ethernet interface view, port group view, Layer-2 aggregate interface view
Default Level
2: System level
Parameters
vlan-id: VLAN ID, in the range of 1 to 4094
Description
Use the port trunk pvid vlan command to configure the default VLAN ID for the trunk port.
Use the undo port trunk pvid command to restore the default.
By default, the default VLAN of a trunk port is VLAN 1.
You can use a nonexistent VLAN as the default VLAN for a trunk port. Removing the default VLAN of a trunk port with the undo vlan command does not affect the setting of the default VLAN on the port.
l In port group view, this command applies to all ports in the port group. For information about port groups, refer to Ethernet Interface Configuration in the Access Volume.
l In Layer-2 aggregate interface view, this command applies to the Layer-2 aggregate interface and all its member ports. After you perform the configuration, the system starts applying the configuration to the aggregate interface and its aggregation member ports. If the system fails to do that on the aggregate interface, it stops applying the configuration to the aggregation member ports. If it fails to do that on an aggregation member port, it simply skips the port and moves to the next port. For information about Layer-2 aggregate interfaces, refer to Link Aggregation Configuration in the Access Volume.
l The local and remote trunk ports must use the same default VLAN ID for the traffic of the default VLAN to be transmitted properly.
l After configuring the default VLAN for a trunk port, you must use the port trunk permit vlan command to configure the trunk port to allow packets from the default VLAN to pass through, so that the port can forward packets from the default VLAN.

Examples
# Configure VLAN 100 as the default VLAN of the trunk port GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] port link-type trunk
[Sysname-GigabitEthernet1/0/1] port trunk pvid vlan 100
# Configure VLAN 100 as the default VLAN of the trunk Layer-2 aggregate interface Bridge-aggregation 1, assuming Bridge-aggregation 1 does not have member ports.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] port trunk pvid vlan 100
# Configure VLAN 100 as the default VLAN of the trunk Layer-2 aggregate interface Bridge-aggregation 1. Among the member ports of the aggregation group corresponding to Bridge-aggregation 1, GigabitEthernet 1/0/2 is an access port and GigabitEthernet 1/0/3 is a trunk port.

[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] port trunk pvid vlan 100
Error: Failed to configure on interface GigabitEthernet 1/0/2! This port is not a Trunk port!
The output above shows that the configuration on Bridge-aggregation 1 and the member port GigabitEthernet 1/0/3 succeeded; the configuration on GigabitEthernet 1/0/2 failed because GigabitEthernet 1/0/2 was not a trunk port.
