4.5.14 VLAN Setting Example:
- Separate VLANs
- 802.1Q VLAN Trunk
4.5.14.1 Two Separate 802.1Q VLANs
The diagram shows how the Industrial Managed Switch handles Tagged and Untagged traffic flow for two VLANs. VLAN Group
2 and VLAN Group 3 are separated VLANs. Each VLAN isolates network traffic so only members of the VLAN receive traffic
from the same VLAN members. The screen in
Industrial Managed Switches.
VLAN Group
VLAN Group 1
VLAN Group 2
VLAN Group 3
The scenario is described as follows:
Untagged packet entering VLAN 2
While [PC-1] transmits an untagged packet entering Port-1, the Industrial Managed Switch will tag it with a VLAN
1.
Tag=2. [PC-2] and [PC-3] will receive the packet through Port-2 and Port-3.
2.
[PC-4], [PC-5] and [PC-6] receive no packet.
While the packet leaves Port-2, it will be stripped away its tag becoming an untagged packet.
3.
While the packet leaves Port-3, it will keep as a tagged packet with VLAN Tag=2.
