Figure 5-1:Example of a port-based VLAN

Even though they are physically connected to the same switch, for the members of the different VLANs to communicate, the traffic must go through the IP routing functionality provided in the Summit. This means that each VLAN must be configured as a router interface with a unique IP address.

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.
