HP Moonshot Switch Module CLI Command Reference
nsf restart-interval
Use this command to configure the number of seconds that the restarting router asks its neighbors to wait
before exiting helper mode. This is referred to as the grace period. The restarting router includes the grace
period in its grace LSAs. For planned restarts (using the
initiate failover command), the grace LSAs are sent
prior to restarting the management unit, whereas for unplanned restarts, they are sent after reboot begins.
The grace period must be set long enough to allow the restarting router to reestablish all of its adjacencies and
complete a full database exchange with each of those neighbors.
no nsfrestart-interval
Use this command to revert the grace period to its default value.
nsf helper
Use this command to enable helpful neighbor functionality for the OSPF protocol. You can enable this
functionality for planned or unplanned restarts, or both.
