5.3.2 VLAN setting example:
5.3.2.1 Two separate 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 5-5appears and Table 5-2 describes the port configuration of switch.

VLAN Group | VID | Untagged Members | Tagged Members |
| | | |
VLAN Group 1 | 1 | Port-1,Port-2 | Port-3 |
| | | |
VLAN Group 2 | 2 | Port-4,Port-5 | Port-6 |

VLAN Group 3 | 3 | Port-7~Port-24 | N/A |

Table 5-2VLAN and Port Configuration
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.
Untagged packet entering VLAN 3
1.While [PC-4]transmit an untagged packet enters Port-4, the switch will tag it with a VLAN Tag=3. [PC-5]and [PC-6]will received the packet through Port-5and Port-6.
2.While the packet leaves Port-5, it will be stripped away it tag becoming an untagged packet.
3.While the packet leaves Port-6, it will keep as a tagged packet with VLAN Tag=3.
#Notice:
At this example, VLAN Group 1 just set as default VLAN, but only focus on VLAN 2 and VLAN 3 traffic flow.
