Hi Experts,

If root bridge for a specfic user vlan is not the core switch of the network  and if the root bridge cost from core switch is very high does that affect the users connected to that vlan?

Thanks,
phoenix

Things will still work but it may not be the most efficient path through the network.  Best to make the core switch the root bridge for that VLAN.

Hi Expert,

Can this command be run during production times?I assume spanning tree will be recalculated when this command is issued

Yes, a recalculation will occur so it's best to run off-hours or during maintenance window just in case.
