You can configure CoS features to meet your application needs. Because the components
are generic, you can use a single CoS configuration syntax across multiple routing devices.
CoS mechanisms are useful for two broad classes of applications. These applications
can be referred to as in the box and across the network.
In-the-box applications use CoS mechanisms to provide special treatment for packets
passing through a single node on the network. You can monitor the incoming traffic on
each interface, using CoS to provide preferred service to some interfaces (that is, to some
customers) while limiting the service provided to other interfaces. You can also filter
outgoing traffic by the packet's destination, thus providing preferred service to some
destinations.
