Changes in Behavior


The following changes in behavior are introduced with NorthStar Controller Releases 6.0.1 and 6.0.2.

  • Starting with NorthStar Release 6.0.1, the default value for the pcs_ecmp_tree_calculation parameter in northstar.cfg has been changed to True. It is no longer necessary for users of SR networks to change this parameter in order to enable ECMP tree calculation (as it was in NorthStar 6.0.0).

  • Starting with NorthStar Release 6.0.1, the link naming convention changed to include the router ID to better support link migration. For upgrades from a release prior to 6.0.1 to release 6.0.1 or later, this change could cause a duplication of links. To correct the displayed topology, run a network cleanup task from the Task Manager or manually delete the old versions of the links (displayed in red with a status of Unknown). You will not encounter this issue when you do a fresh install.


    After you delete the old versions of the links, you must redefine any link thresholds or other configured link options.
