Chapter 1 VLAN Configuration
1.1 VLAN Overview
Virtual Local Area Network (VLAN) groups the devices of a LAN logically but not
physically into segments to implement the virtual workgroups. IEEE issued the IEEE
802.1Q in 1999, which was intended to standardize VLAN implementation solutions.
Through VLAN technology, network managers can logically divide the physical LAN
into different broadcast domains. Every VLAN contains a group of workstations with the
same demands. The workstations of a VLAN do not have to belong to the same
physical LAN segment.
With VLAN technology, the broadcast and unicast traffic within a VLAN will not be
forwarded to other VLANs, therefore, it is very helpful in controlling network traffic,
saving device investment, simplifying network management and improving security.
1.2 Configure VLAN
To configure a VLAN, first create a VLAN according to the requirements.
Main VLAN configuration includes:
z
Enable/Disable VLAN feature
z
Create/Delete a VLAN
z
Add Ethernet ports to a VLAN
z
Set/Delete VLAN description character string
1.2.1 Enable/Disable VLAN Feature
After the VLAN feature is disabled, the packets will be transmitted according to MAC
address but not adding VLAN Tag, thereby disabling the function of VLAN isolation. You
still may configure IP address of the default management VLAN interface 1, thereby
performing remote management such as Telnet and web management.
You can use the following command to enable or disable the VLAN feature on a device.
Perform the following configuration in system view.
