Enabling FSPF

FSPF-related functions can work in a VSAN only after you enable FSPF for the VSAN.
To enable FSPF:
Step
1. Enter system view.
2. Enter VSAN view.
3. Enable FSPF for the VSAN.

Configuring the shortest SPF calculation interval

When the LSDB changes, SPF calculations occur and consume CPU resources. To prevent frequent SPF
calculations from overconsuming the CPU, you can configure the shortest SPF calculation interval.
The shortest SPF calculation interval defines the minimum interval between two consecutive SPF
calculations. A smaller value means that FSPF responds faster to fabric changes by recalculating routes
in a VSAN, but it requires more CPU resources.
To configure the shortest SPF calculation interval:
Step
1. Enter system view.
2. Enter VSAN view.
3. Configure the shortest SPF
calculation interval.
