Figure 6-1: Example of a port-based VLAN on the Summit7i switch
For the members of the different IP VLANs to communicate, the traffic must be routed
by the switch, even if they are physically part of the same I/O module. This means that
each VLAN must be configured as a router interface with a unique IP address.

PANNING SWITCHES WITH PORT-BASED VLANS
To create a port-based VLAN that spans two switches, you must do two things:
1 Assign the port on each switch to the VLAN.
2 Cable the two switches together using one port on each switch per VLAN.
Figure 6-2 illustrates a single VLAN that spans a BlackDiamond switch and a Summit7i
switch. All ports on the BlackDiamond switch belong to VLAN Sales. Ports 1 through 29
on the Summit 7i switch also belong to VLAN Sales. The two switches are connected
using slot 8, port 4 on System 1 (the BlackDiamond switch), and port 29 on System 2
(the Summit7i switch).
