A QoS class determines the priority and bandwidth for
traffic matching a
QoS
Policy rule. You can use a
QoS
Profile to define QoS classes. There are up to eight definable
QoS classes in a single QoS profile. Unless otherwise configured,
traffic that does not match a QoS class is assigned a class of 4.
QoS
Priority Queuing and
QoS
Bandwidth Management, the fundamental mechanisms of a QoS
configuration, are configured within the QoS class definition (see
Step
4). For each
QoS class, you can set a priority (real-time, high, medium, and
low) and the maximum and guaranteed bandwidth for matching traffic.
QoS priority queuing and bandwidth management determine the order
of traffic and how traffic is handled upon entering or leaving a
network.
