NSF Summary
Use the NSF Summary page to change the administrative status of the NSF
feature and to view NSF information.
NOTE:
The OSPF feature uses NSF to enable the hardware to continue forwarding
IPv4 packets using OSPF routes while a backup unit takes over stack master
responsibility. To configure NSF on a stack that uses OSPF or OSPFv3, see "NSF
OSPF Configuration" on page 958 and "NSF OSPFv3 Configuration" on page 975.
To display the NSF Summary page, click System → Stack Management →
NSF Summary in the navigation panel.

To cause the maser unit to failover to the standby unit, click Initiate Failover.
The failover results in a warm restart of the stack master. Initiating a failover
reloads the stack master, triggering the backup unit to take over.
