This chapter covers port-based VLAN, MAC-based VLAN, protocol-based VLAN, and IP subnet-based
VLAN. The port-based VLAN implementation is the basis of all other VLAN implementations. To use any
other VLAN implementations, you must configure port-based VLAN settings.
You can configure all these types of VLANs on a port at the same time. When the switch is determining
which VLAN a packet that passes through the port should be assigned to, it looks up the VLANs in the
default order of MAC-based VLAN, IP sub-based VLAN, protocol-based VLAN, and port-based VLAN.

Configuring basic VLAN settings
Configuration restrictions and guidelines
•
As the default VLAN, VLAN 1 cannot be created or removed.
•
You cannot manually create or remove VLANs reserved for special purposes.
•
To delete a protocol reserved VLAN, voice VLAN, management VLAN, dynamic VLAN, VLAN with
a QoS policy applied, control VLAN for a smart link group, control VLAN for an RRPP domain,
remote probe VLAN for remote port mirroring, remove the configuration from the VLAN first, and
execute the
undo vlan
command.
Configuration procedure
To configure basic VLAN settings:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create a VLAN and
enter its view, or create
VLANs in batches.
vlan
{
vlan-id1
[
to
vlan-id2
]
|
all
}
Optional.
By default, only the default VLAN (VLAN 1)
exists in the system.
3.
Enter VLAN view.
vlan
vlan-id
Required only when you create VLANs in
batches.
4.
Configure a name for
the VLAN.
name
text
Optional.
By default, the name of a VLAN is its VLAN
ID (
VLAN 0001
, for example).
5.
Configure a description
for the VLAN.
description
text
Optional.
The default description is VLAN
vlan-id
,
which is the ID of the VLAN. For example,
the description of VLAN 100 is
VLAN 0100
by default.
