Router Chassis Configuration Guidelines

You can configure properties of the router chassis, including the clock source, conditions that activate the red and yellow alarm LEDs on the router's craft interface, and SONET/SDH framing and concatenation properties for individual Physical Interface Cards (PICs).

To configure router chassis properties, include the following statements at the [edit chassis] hierarchy level: 

chassis {

    aggregated-devices {

        ethernet {

            device-count number;

        }

        sonet {

            device-count number;

        }

    }

    alarm {

        interface-type {

            alarm-name (red | yellow | ignore);

        }

    }

    fpc slot-number {

        pic pic-number {

            atm-cell-relay-accumulation;

            atm-l2circuit-mode (cell | aal5 | trunk trunk);

            vtmapping number;

            ce1 {

                e1 port-number {

                    channel-group group-number timeslots slot-number;

                }

            }

            ct3 {

                port port-number {

                    t1 link-number {

                        channel-group group-number timeslots slot-number;

                    }

                }

            }    

            framing (sdh | sonet);

            idle-cell-format {

                itu-t;

                payload-pattern;

            }

            max-queues-per-interface (8 | 4);

            mlfr-uni-nni-bundles number;

            no-concatenate;

            sparse-dlcis;

            vtmapping (itu-t | klm);     

        }

    }

    (packet-scheduling | no-packet-scheduling);

    no-concatenate;

    (source-route | no-source-route);

    redundancy {

        failover on-loss-of-keepalives;

        graceful-switchover (disable | enable);

        keepalive-time seconds;

        routing-engine slot-number (master | backup | disabled);

        sfm slot-number (always | preferred);

        ssb slot-number (always | preferred);

    }

    vrf-mtu-check;

}
