service-policy (policy-map class)
This example shows how to create a hierarchical service policy in which all levels are present. This
configuration associates a class-level policy map with a VLAN-level policy map, associates the
VLAN-level policy map with a physical-level policy map, and attaches the physical-level policy map to
a port.
