Configuration Steps
The following steps can be used to setup this example network. Since each step involves
entering several instances of a command type, a single practical command entry is shown
at the end of each step. The set of steps comprise the following:
1. Create VLANs on the switch.
2. Create access control lists (ACLs) that will match the data flows between local subnets.
3. Create ACLs that will match the data flows between local devices and other
destinations.
4. Setup class-maps for each department and apply an access-list to each of the class-
maps.
5. Setup class-maps for each department’s wide area connection and apply an access-
list to each of these class-maps.
6. Create the departmental policy-maps and associate them with their appropriate
class-maps.
7. Apply these policy-maps to their appropriate ports.
These class-maps and ACLs are shown diagrammatically in Figure 38-11 below.
