STP priority is configured to force FSX-A to be the root bridge for VLANs RED and BLUE. The STP
priority on FSX-B is configured so that FSX-B is the root bridge for VLANs GREEN and BROWN.
FIGURE 74 More complex port-based VLAN
To configure the Port-based VLANs on the FSX Layer 2 Switches in the above figure, use the
following method.
Configuring port-based VLANs on FSX-A
Enter the following commands to configure FSX-A.
device> enable
device# configure terminal
device(config)# hostname FSX-A
device-A(config)# vlan 2 name BROWN
