The Ethernet II encapsulation format is used here. Besides the Ethernet II encapsulation format, 

other encapsulation formats, including 802.2 LLC, 802.2 SNAP, and 802.3 raw, are also supported 

by Ethernet. The VLAN tag fields are also added to frames encapsulated in these formats for VLAN 

identification. 

z 

For a frame with multiple VLAN tags, the device handles it according to its outer-most VLAN tag 

and transmits its inner VLAN tags as payload.  

 

You can implement VLAN based on: 

z 

Port 

z 

MAC address 

z 

Protocol  

z 

IP subnet 

z 

Policy

Other criteria 

This chapter covers port-based VLAN, MAC-based VLAN, protocol-based VLAN, and IP-based VLAN. 

You can configure the four types of VLANs on a port at the same time. When determining to which 

VLAN a packet passing through the port should be assigned, the device looks up the VLANs in the 

default order of MAC-based VLANs, IP-based VLANs, protocol-based VLANs, and port-based VLANs.  

Follow these steps to configure basic VLAN settings: 

Enter system view 

— 

Create VLANs 

vlan { vlan-id1 [ to vlan-id2 ] | 
all } 

Optional 

Use this command to create VLANs in 
bulk. 

Enter VLAN view 

vlan vlan-id 

Required 

If the specified VLAN does not exist, 
this command creates the VLAN first. 

By default, only the default VLAN (that 
is, VLAN 1) exists in the system.  

Configure a name for the 
current VLAN 

name text 

Optional 

By default, the name of a VLAN is its 
VLAN ID, VLAN 0001 for example.  

Configure the description 
of the current VLAN 

description text 

Optional 

VLAN ID is used by default, VLAN 
0001 for example.
