Configuring ATM CoS on the Logical Interface

To apply the ATM scheduler map to a logical interface, include the atm-scheduler-map statement:



atm-scheduler-map (map-name | default);

When you add or change a scheduler map, the associated logical interface is taken offline and then brought back online immediately. For ATM CoS to take effect, you must configure the VCI and VPI identifiers and traffic shaping on each VC by including the following statements:




vci vpi-identifier.vci-identifier;

shaping {
(cbr rate | rtvbr peak rate sustained rate burst length  | vbr peak rate sustained rate burst length);
}

You can include these statements at the following hierarchy levels:

[edit interfaces interface-name unit logical-unit-number]
[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]

For more information, see the JUNOS Network Interfaces Configuration Guide.

You can also apply a scheduler map to the chassis traffic that feeds the ATM interfaces. For more information, see Associating the Scheduler Map with the Packet Forwarding Component Queues.
