I'm about to deploy a new VX9000 cluster and have read in the best practices that in a centralized/NOC deployment mode it's best to create a separate RF-domain for the controllers. In our case we will have each instance (standby/active) in different subnets so would we add both to the same RF-Domain? I don't think it's an issue as they would build the cluster up on layer 3 mint links?

Thanks Ondrej

Hi Bruno,

IP links in different subnets are not a problem, but both devices shall stay in same RF-Domain.
Either keep both in "default" or move them to new one just for the cluster.

To maintain hierarchical structure, there must NOT be any AP in the RF-Domain where cluster resides.

Regards,
Ondrej

Ondrej,

Is there any information as to WHY there must not be any AP in the RF-Domain where the cluster resides? All the docs, training, etc. say not to do it, but the understanding of a concept is reinforced when the underlying cause/effects are explained.
Thanks!
