interim update

hello
how can i set “interim update” to reduce traffic between mikrotik routers and my radius manager server?
can i set it, for example, to 30 minutes ?
my users have only monthly accounts

Yes, use 30m or 1h.. I think its no problem

I use 10 minutes so i can se things happening faster.

If your RADIUS server is inside your network, then it is not so much traffic.
