Documentation Updates


This section lists the errata and changes in Junos OS Release 17.2R2 documentation for MX Series.

Subscriber Management Access Network Guide

  • The “Configuring the L2TP Resynchronization Method” and “disable-failover-protocol (L2TP)” topics have been updated to state that you can configure the LNS to support only silent failover for peer resynchronization. This capability has been supported on both the LAC and the LNS since Junos OS Release 11.2.

Subscriber Management Provisioning Guide

  • Support for the packet-triggered subscribers and policy control rule base (PTSP) feature was discontinued starting in Junos OS Release 13.1R1, but this was not reflected in the documentation. Text exclusive to PTSP has been removed from the Broadband Subscriber Sessions Feature Guide. This includes all CLI topics and the following chapters:

    • “Configuring the PTSP Feature to Support Dynamic Subscribers”

    • “Configuring the PTSP Partition to Connect to the External Policy Manager”

    • “Configuring PTSP Services and Rules”

    • “Monitoring and Managing Packet-Triggered Subscribers”

    Topics for other features that refer to PTSP are updated to report the end of support.

  • The Broadband Subscriber Sessions Feature Guide did not report that you can suspend AAA accounting, establish a baseline of accounting statistics, and resume accounting. This feature was introduced in Junos OS Release 15.1R4.
