4.3.3.8.1 Two Separate 802.1Q VLANs
The diagram shows how the Managed Metro 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 4-3-3-7 appears and Table 4-3-3-8 describes the port configuration of the
Managed Metro Switches.

The scenario is described as follows:
Untagged packet entering VLAN 2
1. While [PC-1] transmit an untagged packet enters Port-1, the Managed Metro 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.
