#### To Edit the Node Agent’s Listener for JMX

The node agent uses JMX to communicate with the Domain Administration Server. Therefore it must have a port to listen on for JMX requests, and other listener information.

1. In the tree component, expand the Node Agents node.
2. Select the node agent configuration to edit.
3. Click the JMX tab.
4. In the Address field, enter an IP address or host name.

   Enter `0.0.0.0` if the listener listens on all IP addresses for the server using a unique port value. Otherwise, enter a valid IP address for the server.

5. In the Port field, type the port on which the node agent’s JMX connector will listen.

   If the IP address is `0.0.0.0`, the port number must be unique.

6. In the JMX Protocol field, type the protocol that the JMX connector supports.

   The default is rmi_jrmp.

7. In the Realm Name field, type the name of the realm that handles authentication for the listener.
8. Click the checkbox next to Accept All Addresses to allow a connection to all IP addresses.

   The node agent listens on a specific IP address associated to a network card or listens on all IP addresses. Accepting all addresses puts the value `0.0.0.0` in the “listening host address” property.

9. Client Hostname field displays the name of the application server host.
10. Click Save.
