4.6.7 VLAN setting example:
 Separate VLAN
 802.1Q VLAN Trunk
 Port Isolate
4.6.7.1 Two Separate 802.1Q VLANs
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 in Figure 4-6-7 appears and Table 4-6-8 describes the port configuration of the Managed
Switches.

Table 4-1: VLAN and Port Configuration
The scenario is described as follows:
 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.
