6. About VLAN and QoS
6.1 VLAN
The VLAN set ting of a switch can divide the switch to several switching
segments. The network connections on different VLANs can not send or
receiver data from each other. Even broadcast packet s can not be transferred
between VLANs. So, the VLAN function is often used for user's security
application.
Here are two examples for VLAN applications.
The first one is called
Concentration VLAN
setting. In this case, Port (1,16),
(2,16), (3,16), (4,16), …, (13,16), (14,16), (15,16) are in different VLANs and
Port 16 is the common port for uplink or Internet connection. But the data
transfer between Port 1, 2, 3, 4, …, 13, 14, 15 are impossible for such
configuration.
The second one is the default VLAN setting of the switch. Every port belongs
to the same VLAN and can communicate with each other.
Please refer to Section 7 to configure the VLAN from console port.
