    Hi Experts,

     

    What is the function of the "Loop-timing - sonect options?" Under the Ethernet interface what does this command do? Does is syncronizes clock between STM\SDH and Ethernet? Please help me in understanding.

     

    CSTM1-sonet-options {
            interfaces {
                <e1-*/*/*:0> {
                    sonet-options {
                        loop-timing;


    interfaces {
        apply-groups CSTM1-sonet-options;
        ge-0/0/0 {
            mtu 4474;
            unit 0 {
                description TO_Trans_Asia_America_ge-0/0/1;
                family inet {
                    address 220.224.148.6/30;
                }
                family mpls;

     

    Regards

    Hi,

     

    when you include "loop-timing" option, you will configure SONET/SDH or DS3-level clocking. Because by default, internal clocking (line timing) is used on channelized IQ and IQE interfaces.

    Hi, Thanks . I got you what your point but I am not sure what this clocking option has got to do with Ethernet?

    Hi,

     

    It only apply on E1 and T1 interfaces you configure on channelized IQ and IQE PICs
