Summary: Used to determine whether multicast is available.
Syntaxgs> admin multicastTest [variable[variable]] DescriptionThe admin multicastTest utility is used to determine whether multicast is available. It determines whether a multicast socket can be created and a request announcement can be sent.
This multicast utility serves to check multicast communication between sender and receiver running on different machines. You should run this utility from two different shells, where one should run from the sender machine and the other from the receiver machine. The sender machine should display the round trip reply time from all receiver machines. If multicast is configured properly on your machine and network, you should see the following message in your sender machine: Reply from 192.138.120.56:5558 bytes=100 time=1.539ms
