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]

framing (sdh | sonet)

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 (16 | 32);

loopback (local | remote);



mpls {



pop-all-labels {

required-depth number;
}


}



path-trace trace-string;
(payload-scrambler | no-payload-scrambler);

rfc-2615;



trigger {

defect ignore;

defect hold-time up milliseconds down milliseconds;
}


}

vtmapping (itu-t | klm);
(z0-increment | no-z0-increment);

speed (oc3 | oc12 | oc48);

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:
