Figure 7 Example of a port-based VLAN on the Switch 9100

Even though they are physically connected to the same switch, in order for the members of the different VLANs to communicate, the traffic must go through an IP router.

Spanning Switches with Port-Based VLANs

To create a port-based VLAN that spans two switches, you must do two things:

■Assign the port on each switch to the VLAN.

■Cable the two switches together using one port on each switch per VLAN.
