Q: How is Clearpass licensing calculated in a cluster?
A: Clearpass uses a common distribution algorithm to calculate the used licenses for a cluster:
Unique devices authenticated by the node + common mac’s
For example: if we have 4 x 5k nodes,
common mac's from all the nodes are: 2000, cluster will distribute them equally on all the nodes. 2000/4
Node1, unique auths : 2500 + 500 common mac auths = 3000
Node2, unique auths: 2300 + 500 common mac auths = 2800
Node3, unique auths: 2630 + 500 common mac auths = 3130
NOde4, unique auths: 2200 + 500 common mac auths = 2700
Total cluster used authentications showed on the licensing dashboard would be : 11630 used out of 20000.
