Example: Typical IEEE 802.1Q VLAN Configuration
Suppose that the switch port 3, 4 and 5 have the following requirements: Port 3 and
Port 5 can communicate with each other. Port 4 and Port 5 can communicate with
each other. But port 3 and Port 4 can't communicate with each other, as the picture
below. Do not consider other ports, how to set the VLAN?
Example Analysis
Configure the “Type” of Port3, Port4 and Port5 as Access. Port3, Port 4 and Port 5 are
set with different forwarding entries; forwarding entries can enable the communication
between two ports.
Analyse the port forwarding entries design as below:
Port 3
Port3 and Port5 can communicate with each other. Port3 forwarding entries
include Port3 and Port5. Therefore, a forwarding entry PVID3 is designed,
including Port 3 and Port 5. Configure the "Type" of Port 3 and Port 5 to U.
Port 4
Port 4 and Port 5 can communicate with each other. Port 4 forwarding entries
include Port 4 and Port 5. Therefore, a forwarding entry PVID4 is designed,
including Port 4 and Port 5. Configure the "Type" of Port 4 and Port 5 to U.
Port 5
Port 5 and Port 3, Port 4 can communicate with each other, Port 5 forwarding
entries include Port 3, Port 4. Therefore, design a forwarding entry PVID5,
including Port 3, Port 4. Configure the "Type" of Port 3 and Port 4 to U.
According to the forwarding entry analysis of Port 3, Port 4 and Port 5, forwarding
entry design picture as follows:
