Subject Re: Cluster ID and tag: identification of the cluster
Date Wed, 28 Aug 2019 08:26:45 GMT
Hi Sergey,

Would cluster tag be isolator of two clusters? E.g. I want in the same
network create 2 clusters, e.g. for educational purposes. Can I select
cTag=dpavlov, cTag=schugunov and these would be independent clusters?
