Router Chassis Configuration Guidelines

You can configure properties of the router chassis, including the clock source, conditions that activate the red and yellow alarm light-emitting diodes (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, you include statements at the [edit chassis] hierarchy level of the configuration: 

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);

            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;

            }

        mlfr-uni-nni-bundles number;

            no-concatenate;

            sparse-dlcis;

            vtmapping (itu-t | klm);     

        }

    }

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

    vrf-mtu-check;

    (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);

    }

}
