[tcp://<remote server>:<port>]
*Configures the input to listen on a specific TCP network port.
*If a <remote server> makes a connection to this instance, the input uses this stanza to configure itself.
*If you do not specify <remote server>, this stanza matches all connections on the specified port.
*Generates events with source set to "tcp:<port>", for example: tcp:514
*If you do not specify a sourcetype, generates events with sourcetype set to "tcp-raw"

Reference:
The deployer. This is a Splunk Enterprise instance that distributes apps and other configurations to the cluster members. It stands outside the cluster and cannot run on the same instance as a cluster member. It can, however, under some circumstances, reside on the same instance as other Splunk Enterprise components, such as a deployment server or an indexer cluster master node.
