identifier might be longer then 16 bytes. The SDH standards define a maximum
16-byte path trace. For this reason, the default path trace identifier might be truncated
in SDH mode. You can prevent the path trace identifier from being truncated in SDH
mode by configuring a path trace identifier that is under 16-bytes long. In SONET
mode, a path trace identifier can be up to 64-bytes long.
For DS3 channels on a channelized OC12 interface, you can configure a unique path
trace for each of the 12 channels. Each path trace can be up to 16 bytes. For channels
on a channelized OC12 intelligent queuing (IQ and IQE) interface, each path trace
can be up to 64 bytes.
To configure a path trace identifier, include the

A common convention is to use the circuit identifier as the path trace identifier.
To display the local router s path trace identifier, issue the
on the remote router.
Configuring SONET/SDH HDLC Payload Scrambling
SONET/SDH HDLC payload scrambling, which is enabled by default, provides better
link stability. Both sides of a connection must either use or not use scrambling.
NOTE: HDLC payload scrambling conflicts with traffic shaping configured using leaky
bucket properties. If you configure leaky bucket properties, you must disable payload
scrambling, because the JUNOS Software rejects configurations that have both features
enabled. For more information, see "Configuring Receive and Transmit Leaky Bucket
Properties on SONET/SDH Interfaces" on page 931.
On a channelized OC12 interface, the
