You will need to obtain test_igmp_multicasting.c and wtest_multicasting.exe from Support to perform the demo.
How to perform this test :
Execute (test_igmp_multicasting.c) on the embedded side. The open up a
MS-DOS window and type in
C:>wtest_multicasting (IP address of the host in multicasting group)
(port number 7) (number of times the data to be sent to the server)
(name of the file containing the data)
C:>wtest_multicasting 126.96.36.199 7 100 test.txt
Or you can use default values
The IP address added to the multicasting group are as follows:
188.8.131.52, 184.108.40.206, 220.127.116.11, 18.104.22.168, 22.214.171.124,
126.96.36.199, 188.8.131.52, 184.108.40.206, 220.127.116.11, and 18.104.22.168.
Out of these 10 IP addresses which are added to the multicast group,
4 of them are removed later. The IP addresses which are removed
(22.214.171.124, 126.96.36.199, 188.8.131.52, and 184.108.40.206)
doesn't get an echo back from the server.
You have to send a message with only "q" to quit. Save it in a file
and use the first example to do it. Once it is sent you should hit
the break point in TEST_Finished.
After we hit the break point in TEST_Finished, check out the variables
test_errors and MEM_Buffers_Used. The global variables test_errors and
MEM_Buffers_Used should both be equal to 0; however, if you are using
ethernet, MEM_Buffers_Used may reflect buffers allocated by the driver.
If the variables do not meet this criteria, perform the test again.
After one or two attempts, both global variables should meet the
above criteria, otherwise, the test has failed.
