Multicast Test Using NDIT

This section describes how to run a multicast test using NDIT. Select the Multicast test tab in the NDIT main window. The Multicast test panel appears.

There are two options for the multicast test:

Group Address

The Group IP multicast address at which the test station will send the packets.

UDP Port

The UDP port at which the packets will be delivered.

To run a multicast test, click either the Single or IP Range button in the Launch Text box.

Clicking the Single button will send a command to the target to create an IGMP Join request for the specified Group Address, and create a UDP socket that listens for incoming traffic on the specified UDP port. Upon receiving a packet on the specified UDP port, the target will reply to the packet source with the received payload. In return, NDIT will listen to the target reply, and determine if the multicast test was successful.

Clicking the IP Range button will do the exact same test as the Single button, but will do the test for the IP address range from xxx.xxx.xxx.0 to xxx.xxx.xxx.255
