6.4 Layer 2 Configuration
6.4.1
VLAN Configuration
VLAN (virtual local area network), VLAN is a LAN (LAN) equipment from the logical partition (not
physically divided into one segment (or smaller LAN), to achieve the data exchange technology of virtual
work groups (unit). The benefits of VLAN are mainly:
1, Port separation. Even on the same switch, the port on the different VLAN is not able to communicate.
Such a physical switch can be used as a logical switch.
2, Network security. VLAN cannot be directly communication, to eliminate the security of broadcast
information.
3, Flexible management. Change users belong to the network does not have to change the port and
connection, only to change the software configuration on it.
That is in the same VLAN can communicate with each other, in a different VLAN cannot communicate
with each other. A VLAN with VLAN ID to identify, with the same VLAN ID is the same VLAN.
6.4.1.1 PVlan configuration
Port VLAN mode can be configured (access, trunk, translate), VLAN ID: PVID.
(Figure 6.4.1.1 )
Access: port can only belong to 1 VLAN, generally used to connect the user equipment. All of the default
ports belong to the access port;
Trunk: port can belong to more than one VLAN, you can receive and send multiple VLAN packets,
generally used for network equipment connection;
