 # An optional class to configure incoming network ports on the host that are
 # relevant to the Cassandra installation.  If firewalls are being managed
 # already, simply do not include this module in your manifest.
 #
 # IMPORTANT: The full list of which ports should be configured is assessed at
 # evaluation time of the configuration. Therefore if one is to use this class,
 # it must be the final cassandra class included in the manifest.
 # @param client_ports [array] Only has any effect if the `cassandra` class is defined on the node.
 #   Allow these TCP ports to be opened for traffic coming from the client
 #   subnets.
 # @param client_subnets [array] Only has any effect if the `cassandra` class is defined on the node.
 #   An array of the list of subnets that are to allowed connection to
 #   cassandra::native_transport_port and cassandra::rpc_port.
 # @param inter_node_ports [array] Only has any effect if the `cassandra` class is defined on the node.
 #   Allow these TCP ports to be opened for traffic between the Cassandra nodes.
 # @param inter_node_subnets [array] Only has any effect if the `cassandra` class is defined on the node.
 #   An array of the list of subnets that are to allowed connection to
 #   `cassandra::storage_port`, `cassandra::ssl_storage_port` and port 7199
 #   for cassandra JMX monitoring.
 # @param public_ports [array] Allow these TCP ports to be opened for traffic
 #   coming from public subnets the port specified in `$ssh_port` will be
 #   appended to this list.
 # @param public_subnets [array] An array of the list of subnets that are to allowed connection to
 #   cassandra::firewall_ports::ssh_port.
 # @param ssh_port [integer] Which port does SSH operate on.
 # @param opscenter_ports [array] Only has any effect if the `cassandra::datastax_agent` is defined.
 #   Allow these TCP ports to be opened for traffic coming to or from OpsCenter
 #   appended to this list.
 # @param opscenter_subnets [array] A list of subnets that are to be allowed connection to
 #   port 61621 for nodes built with cassandra::datastax_agent.
