HP Moonshot Switch Module CLI Command Reference
nsf (Stack Global Config Mode)
This command enables nonstop forwarding feature on the stack. When nonstop forwarding is enabled, if the
management unit of a stack fails, the backup unit takes over as the master without clearing the hardware tables
of any of the surviving units. Data traffic continues to be forwarded in hardware while the management
functions initialize on the backup unit.
NSF is enabled by default. The administrator may wish to disable NSF in order to redirect the CPU resources
consumed by data checkpointing.
If a unit that does not support NSF is connected to the stack, then NSF is disabled on all stack members. When
a unit that does not support NSF is disconnected from the stack and all other units support NSF, and NSF is
administratively enabled, then NSF operation resumes.
