Configuring SONET/SDH Physical Interface Properties

To configure SONET/SDH physical interface properties, include the sonet-options statement at the [edit interfaces interface-name] hierarchy level: 

[edit interfaces so-fpc/pic/port]

sonet-options { 

    aggregate asx;

    aps {

        advertise-interval milliseconds;

        authentication-key key;

        force;

        hold-time milliseconds;

        lockout;

        neighbor address;

        paired-group group-name;

        protect-circuit group-name;

        request;

        revert-time seconds;

        switching-mode (bidirectional | unidirectional);

        working-circuit group-name;

    }

    bytes {

        e1-quiet value;

        f1 value;

        f2 value;

        s1 value;

        z3 value;

        z4 value;

    }

    fcs (32 | 16); 

    loopback (local | remote);

    mpls {

        pop-all-labels {

            required-depth number;

        }

    }

    path-trace trace-string;

    (payload-scrambler | no-payload-scrambler); 

    rfc-2615;

    trigger {

        defect ignore {

            hold-time up milliseconds down milliseconds;

        }

    }

    vtmapping (itu-t | klm);

    (z0-increment | no-z0-increment);

}

Note that when you configure SONET/SDH OC48 interfaces for channelized (multiplexed) mode (by including the no-concatenate statement at the [edit chassis fpc slot-number pic pic-number] hierarchy level), the bytes f1 statement has no effect. Currently, the bytes e1-quiet statement is ignored if you include it in the configuration. The bytes f2, bytes z3, bytes z4, and path-trace options work correctly on channel 0 and work in the transmit direction only on channels 1, 2, and 3. When using no-concatenate, you must specify a channel. For more information, see the JUNOS System Basics Configuration Guide.

For DS3 channels on a channelized OC12 interface, the bytes f1, bytes f2, bytes z3, and bytes z4 options have no effect. The bytes s1 option is supported only for channel 0; it is ignored if configured on channels 1 through 11. The bytes s1 value configured on channel 0 applies to all channels on the interface.

You can also include some of the statements in the sonet-options statement to set SONET/SDH parameters on ATM interfaces.

You can configure the following SONET/SDH physical interface properties:
