Chapter 9 Configuring Resource Management
Configuring Physical Interfaces
Note For a detailed description of rate and WRR scheduling, refer to the Guide to ATM Technology.
To configure the interface service class and WRR value, perform the following tasks, beginning in global
configuration mode:
Example
The following example shows how to configure service class 3 on interface ATM 0/1/0 with a WRR
weight of 5:
Switch(config)# interface atm 0/1/0
Switch(config-if)# atm service-class 3 wrr-weight 5
Displaying the Interface Service Class Information
To display the configuration of an interface in a service class, use the following user EXEC command:
Example
The following example shows the configuration of the interface in a service class:
Switch> show atm interface resource atm 0/0/0
Resource Management configuration:
