Service Manual

The following is a list of the Dell Networking OS version history for this command.
Version Description
9.1.(0.0) Introduced on the S4810 and Z9000.
8.4.2.2 Introduced on the E-Series TeraScale.
8.3.19.0 Introduced on the S4820T.
Usage Information
OSPFv3 graceful restart supports planned-only and/or unplanned-only restarts. The default is support for
both planned and unplanned restarts.
• A planned restart occurs when you enter the redundancy force-failover rpm command to
force the primary RPM to switch to the backup RPM. During a planned restart, OSPF sends out a
Type-11 Grace LSA before the system switches over to the backup RPM.
• An unplanned restart occurs when an unplanned event causes the active RPM to switch to the backup
RPM, such as when an active process crashes, the active RPM is removed, or a power failure happens.
During an unplanned restart, OSPF sends out a Grace LSA when the backup RPM comes online.
By default, both planned and unplanned restarts trigger an OSPFv3 graceful restart. Selecting one or the
other mode restricts OSPFv3 to the single selected mode.
