QoS Configuration for Customer A
This section provides examples of the initial configuration and activation of QoS policies for a customer
switch. Input and output QoS service policies are configured based on the requirements and attached to
relevant ports.
In the initial configuration for Customer A, Fast Ethernet ports 1 through 24 are user network interfaces
(UNIs) and are disabled by default. Gigabit Ethernet ports 1 and 2 are network node interfaces (NNIs)
and are enabled by default.
This is the overall sequence for initial configuration:
Configure classes and policies.
Shut down all active ports.
Attach policies to ports to be activated.
Take the ports out of the shut-down state.
Leave unused ports shut down.
Note these restrictions for configuring output policies:
You can define up to three classes in the output policy map.
The defined classes must be the same as other output policy maps.
The number of defined classes in each output policy map must be same.
You must assign an action to each class; that is, there can be no empty class.
Each class configuration must be based on the classification/marking done in the input policy-map.
This example configures classes for input service policies and defines three classes of service: gold,
silver, and bronze. Because a match-all classification (the default) can have only single classification
criterion, the match-any classification is used so that you can add classification criteria in the future.
