Example 2, VLANs Across Multiple Switches

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: 223 for the Blue VLAN

•Port 3, VLAN ID: 222 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.
