1.2 Configuring Basic VLAN Attributes
Follow these steps to configure basic VLAN attributes:
To do…
Use the command…
Remarks
Enter system view
system-view
—
Create VLANs
vlan
{
vlan-id1
[
to
vlan-id2
]
| all
}
Optional
Using this command can create
multiple VLANs in a bulk.
Enter VLAN view
vlan
vlan-id
Required
If the specified VLAN does not
exist, the command creates the
VLAN and then enters its view.
By default, only the default VLAN
(that is, VLAN 1) exists in the
system.
Specify a descriptive
string for the VLAN
description text
Optional
VLAN ID used by default, for
example, “VLAN 0001”
Note:
z
As the default VLAN, VLAN 1 cannot be created or removed.
z
You cannot manually create or remove reserved VLANs, which are reserved for
specific functions.
z
Dynamic VLANs cannot be removed using the
undo vlan
command.
z
If a VLAN has a QoS policy configured, the VLAN cannot be removed.
z
If a VLAN is configured as a remote-probe VLAN for remote port mirroring, it cannot
be removed using the
undo vlan
command unless its remote-probe VLAN
configuration is removed.
1.3 Basic VLAN Interface Configuration
Hosts of different VLANs cannot communicate directly. That is, routers or Layer 3
switches are needed for packets to travel across different VLANs. VLAN interfaces are
used to forward VLAN packets on Layer 3.
VLAN interfaces are Layer 3 virtual interfaces (which do not exist physically on devices)
used for Layer 3 interoperability between different VLANs. Each VLAN can have one
VLAN interface. Packets of a VLAN can be forwarded on network layer through the
corresponding VLAN interface. As each VLAN forms a broadcast domain, a VLAN can
