Ports Configuration
By default, API Gateway does provide synchronization of the port configuration across API Gateway cluster nodes. If you do not want the ports to be synchronized across API Gateway cluster nodes, set the portClusteringEnabled parameter available under Username > Administration > General > Extended settings in API Gateway to false.
Note:
When this parameter is set to true, all the existing port configurations except the diagnostic port (9999) and the primary port (5555) are removed.
Synchronization of ports configuration does not cover temporary disconnects of a node, therefore, to get a node synchronized, you must restart it. Also, if you do not remove the port configuration, the port can be re-synchronized by performing another update on the same configuration. Therefore, to activate the ports synchronization, do the following:
1. Set the portClusteringEnabled parameter to true.
2. Restart all the cluster nodes.
