This ACL matches traffic to those 2 hosts.

Match anything that matches the above ACL.

For traffic that matches the To-Customer class, set the DSCP markings to CS5 on all packets.
Also set a guaranteed rate of 10,000 kbps for this traffic.

This shapes all traffic going through this policy to 10% of the interfaces speed. It also subjects any traffic going through to the CHILD policy map defined above.

Apply this service policy to traffic that is going out of this interface.

In short, this policy shapes all traffic going out of that sub-interface to 100Mbps. It guarantees at least 10Mbps is available to traffic destined towards 10.0.0.1 and 10.0.0.2 combined.
