Introduction › How a Scheduling Manager and Agents Communicate › Receiver Ports

Receiver Ports

A scheduling manager and agents each have TCP/IP ports to receive messages. The receiver listens on its designated port for messages from one or more senders. When the sender has messages to transmit, it connects to the port of the receiver, sends the messages, and closes the connection.

Receiver port configuration is restricted as follows:

• CA Workload Automation AE and CA Workload Automation CA 7 Edition have only one receiver port. The receiver port can receive messages from multiple agents.
• CA Workload Automation ESP Edition can have multiple receiver ports (for example, to separate encrypted and unencrypted message traffic). Each of these ports can receive messages from multiple agents.
• An agent has only one receiver port. This port can receive messages from multiple scheduling managers.
