STP: Changing the bridge priority of a switch

[Olivier_Delapor]

If I change the STP bridge priority of a switch to a lower value (from 20480 to 16384), using the command:
config stpd s0 priority 16384,

will that change take effect immediately? If not, do I need to restart stpd?

disable stpd s0
enable stpd s0.

I am running ExtremeOS 11.6.5.3

Thank you
