Configuring the Default QoS Objective Table
Resource management provides a table of default objective values for quality of service (QoS) for
guaranteed service categories. These values—either metrics or attributes—are used as the criteria for
connection setup requirements.

Default objective values for QoS for guaranteed service categories can be configured for UNI 4.0

lists the default values of the QoS objective table.
Each objective can have a defined or undefined value. If undefined, the objective is not considered in
connection setup. The table should be configured with the same values for an entire network.

To configure the default QoS objective table, perform the following tasks in global configuration mode:
Example
The following example shows how to change the constant bit rate (CBR) maximum cell loss ratio
objective for cell loss priority (CLP) = 0+1 to 10
objective for cell loss priority (CLP) = 0+1 to 10
