Usage guidelines
Only FCF switches and VSANs operating in FCF mode support this command.
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
# Set the shortest SPF calculation interval in VSAN 2 to 10 seconds.
<Sysname> system-view
[Sysname] vsan 2
[Sysname-vsan2] fspf spf-hold-time 10
