VLAN setting example:
- Separate VLAN
- 802.1Q VLAN Trunk
- Port Isolate
Two separate 802.1Q VLAN
The diagram shows how the Managed 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 is shown
Figure 4-6-8 appears. Table 4-1 describes the port configuration of the Managed Switches.

VLAN Group VID Untagged Members Tagged Members
VLAN Group 1 1 Port-7~Port-24 N/A
VLAN Group 2 2 Port-1,Port-2 Port-3
VLAN Group 3 3 Port-4,Port-5 Port-6
Table 4-1 VLAN and Port Configuration
The scenario described as follow:
„ Untagged packet entering VLAN 2
1. While [PC-1] transmit an untagged packet enters Port-1, the Managed Switch will tag it with a VLAN Tag=2. [PC-2]
and [PC-3] will received the packet through Port-2 and 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-1 and Port-2.
6. While the packet leaves Port-1 and Port-2, it will be stripped away it tag becoming an untagged packet.
