# Defining Network Parameters (ESB Endpoint)

You can define or modify an ESB definition for a recipe or trigger definition.

See TIBCO Rendezvous Administration or the TIBCO Enterprise Message Service documentation for details and the default settings of the parameters in this procedure.

Note: Do not consider any dependencies before performing the following steps.

## Procedure

1. Select option 5 - Define ESB Endpoints and Parameters to go to the Define ESB Endpoints panel.
   For more information about this panel, see Define ESB Endpoints Panel.
2. On the command line, enter `ADD`, and then press Enter to create a new ESB definition.
3. In the ESB Endpoint Extensions panel, set field values to define the ESB. The configurations vary depending on the messaging protocol that is used by Substation ES to communicate with TIBCO applications.
   - For TIBCO Enterprise Message Service:
   1. In the Type field, enter `E` for TIBCO Enterprise Message Service.
   2. In the Startup field, specify (`Y` or `N`) whether this ESB starts during the initialization of Substation ES.
   3. In the URL field, specify the host name or host IP address that Substation ES uses to find the TIBCO Enterprise Message Service server and establish communication.
      Note:
      - For details on setting up EMS ECF connection, see Using Connection Factories.
      - For detail usage of "Substitution", see Substitution Process for EMS ESB Definitions.
   4. In the Port field, specify (if applicable) the value of the TCP port used by the Substation ES ESB.
   5. In the User field, specify (if applicable) a user ID if TIBCO Enterprise Message Service requires a specific ID.
   6. In the Password field, specify (if applicable) a password if TIBCO Enterprise Message Service requires a specific password.
   7. In the TCPIP Stack Name field, specify the IBM stack name to be used with this connection.
   - For TIBCO Rendezvous:
   1. In the Type field, enter `R` for TIBCO Rendezvous.
   2. In the Startup field, specify (`Y` or `N`) whether or not this ESB starts during the initialization of Substation ES.
   3. In the URL field, specify (if applicable) the host name or host IP address that Substation ES uses to find the Rendezvous daemon and establish communication.
   4. In the Port field, specify the daemon port if necessary. The default value is 7500.
   5. In the Service field, specify the UDP service port.
   6. In the Network field, specify (if applicable) the network IP address.
   7. In the Multicast field, specify (`Y` or `N`) whether this ESB is to use multicast addressing.
   8. In the Multicast Address field, specify (if applicable) the multicast addresses.
      Note: You must specify this field if you set the Multicast field to Y.
   9. In the TCPIP Stack Name field, specify the IBM stack name to be used with this connection.
   For more information about the ESB Endpoint Extensions panel, see ESB Endpoint Extensions Panel.
4. Press Enter before exiting the panel.
5. Exit the ESB Endpoint Extensions panel in either of the following ways:
   - Press PFK3.
   - On the command line, enter `END`, and then press Enter.
   When you return to the Define ESB Endpoint panel, you can change the identifier for this new ESB endpoint by overtyping the value in the Identifier field.
6. Review the message displayed in the upper-right corner of the Transformer Configuration panel to verify that your changes have been saved.
