Instant ARM ClientMatch configuration

Greetings to all!

 

Can anybody explain to me more exact a meaning of the next three fields in the RF/ARM settings and its affect on the fork of CM:

CM calculating interval
CM neighbor matching %
CM threshold

Thanks in advance!

CM calculating interval - How often the ClientMatch Algorithm is run and consequently makes decisions.  The defaults are usually adequate and should not be changed.
CM neighbor matching % -
Used for load balancing.  Roughly determines how close access points need to be to be considered in the same "Neighborhood".
CM threshold -
In general the number of users on an AP before Client Match considers load balancing.

Thanks in advance!

Re: Instant ARM ClientMatch configuration

If you lower the percentage, more APs will be considered in the same neighborhood.  That means a client could be load balanced or moved to more access points, which is not necessarily a good thing.  The percentage is really just a factor that could be adjusted by TAC or engineering for testing, but it never is.
