Example 2, VLANs Across Multiple Switches
VLAN Operation and Network Applications 12-27
Switch 2
Switch 2 is set as follows:
1. Two VLANs are added to the list of VLANs using the Device VLAN Configuration screen and
assigned to a FID. In this example they are as follows:
• VLAN ID 2, FID 2, with a VLAN Name of Red
• VLAN ID 3, FID 3, with a VLAN Name of Blue
2. A Port VLAN ID is assigned to each port (1 and 3) as follows using the Port Assignment screen:
• Port 1, VLAN ID: 3 for the Blue VLAN
• Port 3, VLAN ID: 2 for the Red VLAN
These settings change the configuration of the switch, so that Port 1 is part of Blue VLAN, Port
3 is part of Red VLAN, and both are set as frame type of untagged.
3. Port 2 is configured as a 1Q Trunk port as follows using the Port Assignment Configuration
screen:
• Port 2, Port Mode: 1Q Trunk
Port 2 is set as an 802.1Q Trunk port, which makes its Port VLAN List contain all VLANs and
sets all frames forwarded out this port as tagged frames. This completes the transmission path
between Switch 4 and Switch 2.
