Configuring CoS Schedulers for Aggregated Ethernet and SONET/SDH Interfaces

You can apply a class-of-service (CoS) configuration to aggregated Ethernet and aggregated SONET/SDH interfaces. The CoS configuration applies to all member links included in the aggregated interface. You cannot apply different CoS configurations to the individual member links.

To view the summation of the queue statistics for the member links of an aggregate interface, issue the show interfaces queue command. To view the queue statistics for each member link, issue the show interfaces queue aggregated-interface-name command.

To configure CoS schedulers on aggregated interfaces, you can include the following statements at the [edit class-of-service] hierarchy level of the configuration:

class-of-service {

    interfaces {

        interface-name {

            scheduler-map map-name;

            scheduler-map-chassis map-name;

            unit logical-unit-number {

                scheduler-map map-name;

            }

        }

    }

    scheduler-maps {

        map-name {

            forwarding-class class-name scheduler scheduler-name;

        }

    }

    schedulers {

        scheduler-name {

            buffer-size (percent percentage | remainder | temporal microseconds);

            drop-profile-map loss-priority (any | low | medium-low | medium-high | high) 

                    protocol (any | non-tcp | tcp) drop-profile profile-name;

            priority priority-level;

            transmit-rate (rate | percent percentage | remainder) <exact>;

        }

    }

}
