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;

            t1;

            vtmapping (itu-t | klm);     

        }

    }

    lcc number {

        fpc number {

            pic number {

                atm-cell-relay-accumulation;

                atm-l2-circuit-mode (cell | aal5 | trunk trunk);

                framing (sdh | sonet);

                idle-cell-format {

                    itu-t;

                    payload-pattern payload-pattern-byte;

                }

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

                no-concatenate;

            }

        }

        offline;

        online-expected;

    }    

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

    no-concatenate;

    (source-route | no-source-route);

    redundancy {

        failover {

            on-loss-of-keepalives;

            on-disk-failure;

        }

        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;

}

   
NOTE: The configuration statements at the [edit chassis lcc] hierarchy apply only to a routing matrix. For information about a routing matrix, see the TX Matrix Platform and T640 Routing Node Configuration Guidelines and the TX Matrix Platform Hardware Guide.
