of the same port. 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:
• Assign the port on each switch to the VLAN.
• Connect the two switches using one port on each switch per
VLAN.
Figure 7.2 illustrates a single VLAN that spans two 480T routing
switches. All ports on both switches belong to VLAN Sales. The
two switches are connected using port 13 on System 1, and port 16
on System 2.
Figure 7.2: 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 connected to a port on System
2 for each spanned VLAN and each of these ports must also be a
member of the corresponding VLANs.
Figure 7.3 illustrates two VLANs spanning two switches:
• On System 1, ports 9 through 12 are part of VLAN Accounting
and ports 13 through 16 are part of VLAN Engineering.
