Configuring SONET/SDH RFC 2615 Support
RFC 2615, PPP over SONET/SDH, requires certain C2 header byte and FCS settings
that vary from the default values configured in accordance with RFC 1619 (the
previous version of RFC 2615). The newer values are optimized for stronger error
detection, especially when combined with payload scrambling at higher bit rate links.
Table 86 on page 907 shows the older (RFC 1619) and newer (RFC 2615) values,
together with the Juniper Networks default values.

To enable support for the RFC 2615 features, include the

Configuring SONET/SDH Defect Triggers to Be Ignored
A trigger is a defect alarm that causes a physical interface to be marked down. By
default, all defects are honored with no hold time. For SONET/SDH and ATM over
SONET/SDH interfaces only, you can configure individual triggers to ignore a defect,
honor a defect, and apply up and down hold timers to the defect.
Table 87 on page 907 lists the defects you can configure.
