130 Gigabit connections, a Catalyst 6500 multilayer switch is used as the backbone switch.
You can use the workgroup configurations shown in previous examples to create workgroups with
Gigabit uplinks to the Catalyst 6500 switch. For example, you can use switch clusters that have a mix of
Catalyst 2950 switches.
The Catalyst 6500 switch provides the workgroups with Gigabit access to core resources:
