Report a bug 26.3.2. Testing Multicast Using JGroups The following procedure details the steps to test multicast using JGroups if you are using Red Hat JBoss Data Grid : Prerequisites Ensure that the following prerequisites are met before starting the testing procedure. Set the bind_addr value to the appropriate IP address for the instance. For added accuracy, set mcast_addr and port values that are the same as the cluster communication values. Start two command line terminal windows. Navigate to the location of the JGroups JAR file for one of the two nodes in the first terminal and the same location for the second node in the second terminal. Procedure 26.1. Test Multicast Using JGroups Run the Multicast Server on Node One Run the following command on the command line terminal for the first node (replace jgroups.jar with the infinispan-embedded.jar for Library mode): Run the Multicast Server on Node Two Run the following command on the command line terminal for the second node (replace jgroups.jar with the infinispan-embedded.jar for Library mode): Transmit Information Packets Enter information on instance for node two (the node sending packets) and press enter to send the information. View Receives Information Packets View the information received on the node one instance. The information entered in the step should appear here. Confirm Information Transfer Repeat steps 3 and 4 to confirm all transmitted information is received without dropped packets. Repeat Test for Other Instances Repeat steps 1 to 4 for each combination of sender and receiver. Repeating the test identifies other instances that are incorrectly configured. Result All information packets transmitted from the sender node must appear on the receiver node. If the sent information does not appear as expected, multicast is incorrectly configured in the operating system or the network. Report a bug
