Configuring Frame Relay to ATM Interworking Port Adapter Interfaces
Configuring Frame Relay to ATM Resource Management
Example
The following example shows how to configure a Frame Relay to ATM CTT row with non-real-time
variable bit rate (VBR-NRT) service category, committed information rate of 64000 bits per second, a
peak information rate of 1536000 bits per second, and a committed burst size of 8192 bits per second:
variable bit rate (VBR-NRT) service category, committed information rate of 64000 bits per second, a
peak information rate of 1536000 bits per second, and a committed burst size of 8192 bits per second:
Switch(config)# frame-relay connection-traffic-table-row 64000 8192 1536000 vbr-nrt
Allocated index = 64000
Switch(config)#
Displaying the Frame Relay to ATM Connection Traffic Table
To display the Frame Relay to ATM CTT configuration, use the following EXEC command:

Configuring the Interface Resource Management Tasks
The following resource management tasks configure queue thresholds, committed burst size, and service
overflow on Frame Relay interfaces. To change any of these interface parameters, perform the following
steps, in interface configuration mode:
