Configure SONET HDLC Payload Scrambling

Purpose

You might want to configure SONET HDLC payload scrambling (which is the configurable cell payload scrambling mentioned earlier) if it has been disabled. Configuring payload scrambling provides better link stability.

NOTE: Payload scrambling is the default for Juniper Networks routers. To return to the default, that is, to re-enable payload scrambling, delete the no-payload-scrambler statement from the configuration.

Action

To explicitly configure HDLC payload scrambling, follow these steps:

  1. In configuration mode, go to the following hierarchy level:
    2. [edit]

    user@host# edit interfaces so-fpc/pic/port sonet-options
  2. Configure payload scrambling:
    3. [edit interfaces so-fpc/pic/port sonet-options]

    user@host# set payload-scrambler
  3. Verify the configuration:
    4. user@host# show

For example:

[edit interfaces so-0/0/0 sonet-options]

user@host# show 

payload-scrambler;
  1. Commit the configuration:
    2. user@host# commit
