Views VSAN view Predefined user roles network-admin Parameters value: Shortest SPF calculation interval in the range of 0 to 60 seconds. Usage guidelines When the LSDB changes, SPF calculations occur, which consume CPU resources. To prevent frequent SPF calculations from consuming too many CPU resources, you can configure the shortest SPF calculation interval. The shortest SPF calculation interval defines the minimum interval between two consecutive SPF calculations. Setting a small value means that FSPF responds quickly to fabric changes by recalculating routes in a VSAN. A small value consumes more CPU resources.

Parameters
value
: Shortest SPF calculation interval in the range of 0 to 60 seconds.
Usage guidelines
When the LSDB changes, SPF calculations occur, which consume CPU resources. To prevent frequent SPF
calculations from consuming too many CPU resources, you can configure the shortest SPF calculation
interval.
The shortest SPF calculation interval defines the minimum interval between two consecutive SPF
calculations. Setting a small value means that FSPF responds quickly to fabric changes by recalculating
routes in a VSAN. A small value consumes more CPU resources.
Examples
# Configure the shortest SPF calculation interval as 10 seconds in VSAN 2.
