VLAN stands for Virtual LAN. It is a logical LAN, which<br />
can overcome the limitations of a physical network.<br />
Users that belong to different logical LANs can assign<br />
different security levels and resources to be accessed,<br />
which looks like working in different physical LANs. The<br />
transmission direction of the packets on the network<br />
can be effectively controlled via VLAN for successfully<br />
managing network security and performance.<br />

Private VLAN<br />

<strong>L3</strong>/<strong>L2</strong> <strong>Switch</strong><br />
Private VLAN provides primary and secondary VLAN<br />
within a single switch. The client ports can be isolated or<br />
grouped with some ports within the same Community.<br />
Client ports can only communicate with the primary<br />
VLAN - usually the uplink port to upper switch. The client<br />
ports within the same Community can communicate with<br />
each other and forward to private VLAN. The private<br />
VLAN helps to resolve the primary VLAN ID shortage,<br />
client ports’ isolation and network security issues.<br />

QinQ is originally designed to expand the number of<br />
VLANs by adding a tag to the 802.1Q packets.<br />
The original VLAN is usually identified as Customer<br />
VLAN (C-VLAN) and the new added tag - as Service<br />
VLAN(S-VLAN). By adding the additional tag, QinQ<br />
increases the possible number of VLANs. The total<br />
maximum VLAN number of S-VLAN and C-VLAN will<br />
remain limited by the implementation in each networking<br />
device. For example, the <strong>JetNet</strong> 5010G with QinQ<br />
supported can reach up to 256x256 VLANs.<br />
With QinQ, an <strong>Ethernet</strong> network can have a hierarchical<br />
structure. The LAN users can be assigned to C-VLAN,<br />
one or multiple C-VLAN can be aggregated into one<br />
S-VLAN. The administrator can utilize S-VLAN to<br />
isolate traffic from each VLAN. As a result, it reduces<br />
the number of VLANs and provides easy and efficient<br />
network maintenance.<br />
