Licenses for Clustering
You assign feature licenses to the cluster as a whole, not to individual nodes. However, each node of the cluster consumes a separate license for each feature. The clustering feature itself does not require any licenses.
When you add a cluster node to the management center, you can specify the feature licenses you want to use for the cluster. You can modify licenses for the cluster in the area.
Note | If you add the cluster before the management center is licensed (and running in Evaluation mode), then when you license the management center, you can experience traffic disruption when you deploy policy changes to the cluster. Changing to licensed mode causes all data units to leave the cluster and then rejoin. |
