Configuring SONET/SDH HDLC Payload Scrambling
To explicitly enable payload scrambling, perform the following steps:
- In configuration mode, go to the [edit interfaces interface-name sonet-options] hierarchy level, where
the interface-name is so-fpc/pic/port.[edit]user@host# edit interfaces so-fpc/pic/port sonet-options
- Configure the payload-scrambler option to enable
HDLC payload scrambling.[edit interfaces so-fpc/pic/port sonet-options]user@host# set payload-scrambler
You disable HDLC payload scrambling:
- In configuration mode, go to the [edit interfaces interface-name sonet-options] hierarchy level, where
the interface-name is so-fpc/pic/port.[edit]user@host# edit interfaces so-fpc/pic/port sonet-options
- Configure the no-payload-scrambler option to
disable HDLC payload scrambling.[edit interfaces so-fpc/pic/port sonet-options]user@host# set no-payload-scrambler
To re-enable payload scrambling and to return to default setting.
- In configuration mode, go to the [edit] hierarchy
level.user@host# edit
- To return to the default setting, delete the no-payload-scrambler statement from the configuration.[edit]user@host# delete interfaces so-fpc/pic/port sonet-options no-payload-scrambler
On a channelized OC12 interface, the sonet-options payload-scrambler statement is ignored. To configure scrambling on the DS3 channels on the interface, include the t3-options payload-scrambler statement in the configuration for each DS3 channel.
