to a different value. For compatibility with a neighbor device, configure the TPID value on the
device to be the same as the neighbor device.
•
Priority—3-bit long, identifies the 802.1p priority of the frame. For more information, see ACL
and QoS Configuration Guide.
•
CFI—1-bit long canonical format indicator that indicates whether the MAC addresses are
encapsulated in the standard format when packets are transmitted across different media.
Available values include:
0 (default)—The MAC addresses are encapsulated in the standard format.
1—The MAC addresses are encapsulated in a non-standard format.
This field is always set to 0 for Ethernet.
•
VLAN ID—12-bit long, identifies the VLAN to which the frame belongs. The VLAN ID range is 0
to 4095. VLANs 0 and 4095 are reserved, and VLAN 1 is user configurable.
The way a network device handles an incoming frame depends on whether the frame has a VLAN
tag and the value of the VLAN tag (if any). For more information, see "Introduction."
Ethernet supports encapsulation formats Ethernet II, 802.3/802.2 LLC, 802.3/802.2 SNAP, and
802.3 raw. The Ethernet II encapsulation format is used here. For information about the VLAN tag
fields in other frame encapsulation formats, see related protocols and standards.
For a frame that has multiple VLAN tags, the device handles it according to its outermost VLAN tag
and transmits its inner VLAN tags as the payload.

Configuring basic VLAN settings

Step
Enter system view.
1.
(Optional.) Create a
2.
VLAN and enter its
view, or create a list of
VLANs.
Enter VLAN view.
3.
Configure a name for
4.
the VLAN.
Configure the
5.
description of the
VLAN.
Command
system-view
vlan { vlan-id1 [ to vlan-id2 ] |
all }
vlan vlan-id
name text
description text
115
Remarks
N/A
By default, only the system default VLAN
(VLAN 1) exists.
To configure a VLAN after you create a
list of VLANs, you must perform this step.
By default, the name of a VLAN is VLAN
vlan-id. The vlan-id argument specifies
the VLAN ID in a four-digit format. If the
VLAN ID has fewer than four digits,
leading zeros are added. For example,
the name of VLAN 100 is VLAN 0100.
By default, the description of a VLAN is
VLAN vlan-id. The vlan-id argument
specifies the VLAN ID in a four-digit
format. If the VLAN ID has fewer than four
digits, leading zeros are added. For
example, the default description of VLAN
100 is VLAN 0100.
