4.5.3VLAN setting example:

4.5.3.1Two separate 802.1Q VLAN

The diagram shows how the switch handle Tagged and Untagged traffic flow for two VLANs. VLAN Group 2 and VLAN Group 3 are separated VLAN. Each VLAN isolate network traffic so only members of the VLAN receive traffic from the same VLAN members. The screen in Figure 4-11 appears and Table 4-1 describes the port configuration of switch.

The scenario described as follow:

„Untagged packet entering VALN 2

1.While [PC-1]transmit an untagged packet enters Port-1, the switch will tag it with a VLAN Tag=2. [PC-2]and [PC-3] will received the packet through Port-2and Port-3.

2.[PC-4],[PC-5] and [PC-6] received no packet.

3.While the packet leaves Port-2, it will be stripped away it tag becoming an untagged packet.

4.While the packet leaves Port-3, it will keep as a tagged packet with VLAN Tag=2.

„Tagged packet entering VLAN 2

5.While [PC-3]transmit a tagged packet with VLAN Tag=2 enters Port-3, [PC-1]and [PC-2]will received the packet through Port-1and Port-2.

6.While the packet leaves Port-1and Port-2, it will be stripped away it tag becoming an untagged packet.
