VLAN Management
- 33 -
Ensure the network security. The mutual communication between the distinct VLAN
hosts is not permitted to conduct directly, instead, it is realized exclusively through the
router or the messages 3 layer forwarding by the 3 layers switch or other network layer
devices. And that strengthens the security between the different departments in an
enterprise network.
Three VLAN modes are supported by Tenda Smart PoE Switch series: Port VLAN,
ONE-KEY VLAN and 802.1Q VLAN.
Port VLAN
The Port VLAN divisions are based on the physical port. The VLAN ports of the same switch
and divided into the same VLAN are allowed to communicate with each other, but those
across switches are not.
As shown below, the 4 ports of one switch are divided into 2 different VLAN: Port 1 and 2
into VLAN 1, and port 3 and 4 into VLAN 2.
The communication between the VLAN ports divided into the identical VLAN is permitted
only. Therefore in the above example, port 1 can communicate with port 2 solely, the same
as port 3 and 4.
