Spanning Switches with Port-Based VLANs

To create a port-based VLAN that spans two switches, you must do two things:
1Assign the port on each switch to the VLAN.
2Cable the two switches together using one port on each switch per VLAN.
Figure2 illustrates a single VLAN th at spans a BlackDia mond switch and a Summit 300-48 switch . All
ports on the BlackDiamond switch belong to VLAN Sales. Ports 1:1 through 1:24, and port 1:26 on the
Summit 300-48 switch also belong to VLAN Sales. The two switches are connected using slot 8, port 4
on system 1 (the BlackDiamond switch), and port 1:26 on system 2 (the Summit 300-48 switch).
Figure 2: Single port-based VLAN spanning two switches
To create multiple VLANs that span two switches in a port-based VLAN, a port on system 1 must be
cabled to a port on system 2 for each VLAN you want to have span across the switches. At least one
port on each switch must be a member of the corresponding VLANs, as well.
