interface Vlan-interface vlan-id
undo interface Vlan-interface vlan-id
View
System view
Parameter
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 or enter VLAN interface view.
Use the undo interface Vlan-interface
command to delete the VLAN interface.
Related command: display interface Vlan-interface.
Example
# Enter Vlan-interface 1 view
<H3C>
system-view
System View: return to User View with
Ctrl+Z.
[H3C] interface Vlan-interface 1

Syntax
name text
undo name
View
VLAN view
Parameter
text: String
that refers to the name of the current VLAN, in the range of 1 character to 32
characters. It can contain special characters and space.
Parameter
Use the name command to assign a
name to a 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”.
Example
# Specify the name of VLAN 2 to be “test
vlan”.
<H3C> system-view
System View: return to User View with
Ctrl+Z.
[H3C] vlan 2
[H3C-vlan2] name test vlan
Syntax
shutdown
undo shutdown
View
VLAN interface view
Parameter
None
Description
Use the shutdown command to disable
the VLAN interface.
Use the undo shutdown command to
enable the VLAN interface.
By default, a VLAN interface is enabled. In
this scenario, a VLAN interface’s status is determined by the status of
its Ethernet ports, that is, if all the Ethernet ports of the VLAN interface
are down, the VLAN interface is down (disabled); if one or more Ethernet ports
of the VLAN interface are up, the VLAN interface is up (enabled).
If a VLAN interface is disabled, its status
is not determined by the status of its Ethernet ports.
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 all the Ethernet ports belonging to this VLAN.
Example
# Disable Vlan-interface2.
<H3C> system-view
System View: return to User View with
Ctrl+Z.
[H3C] interface Vlan-interface 2
[H3C-Vlan-interface2] shutdown
Syntax
vlan vlan-id
undo vlan vlan-id
View
System view
Parameter
vlan-id: ID
of the VLAN to be created or to be configured. 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
a VLAN.
Note that:
l
VLAN 1 is the default VLAN and cannot be
removed.
l
If the management VLAN to be removed is not the
default management VLAN, VLAN 1 becomes the management VLAN after the current
management VLAN is removed.
Example
# Enter VLAN 1 view.
<H3C> system-view
System View: return to User View with
Ctrl+Z.
[H3C] vlan 1
[H3C-vlan1]
# Delete VLAN 5.
[H3C-vlan1] quit
[H3C] undo vlan 5

are to be created. This argument ranges from 1 to 4,094.
to:
Specifies the VLAN ID range.
vlan-id2:
End VLAN ID of the VLAN ID range. This argument ranges from 1 to 4,094 and need
to be larger than the vlan-id1 argument.
all: Specifies all VLANs.
Parameter
Use the vlan to command to create VLANs
in batches.
Use the undo vlan to command to
remove VLANs in batches.
Note that VLAN 1 is the default VLAN and cannot
be removed.

1.2 Port-Based VLAN Configuration Commands
Syntax
port interface-list
undo port interface-list
View
VLAN view
Parameter
interface-list: List of Ethernet ports. 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 to keyword specifies a group of
successive ports. The port number to the right of the to keyword need to
be larger than or equal to the one to the left of the keyword.
l
&<1-10> means that you can provide up
to ten Ethernet ports/Ethernet port lists.
Parameter
Use the port command to add a port
or multiple ports to a VLAN.
Use the undo port command to remove
a port or multiple ports from a VLAN.
By default, all the ports belong to the
default VLAN.
Caution:
The port command is only applicable to access ports. To add
trunk ports and hybrid ports to a VLAN, you can use the port trunk permit vlan and port
hybrid vlan commands in Ethernet port view. Refer to the Port Command
section in H3C S3100-SI Series Ethernet Switch Command Manual for more.
Example
# Add Ethernet1/0/1 through Ethernet1/0/4
ports to VLAN 2.
<H3C> system-view
System View: return to User View with
Ctrl+Z.
[H3C] vlan 2
[H3C-vlan2] port ethernet1/0/1 to
ethernet1/0/4
