IGMPv3 Source Specific behavior on SG550XG

Hello everyone,

 

I'm experiencing some strange behavior when trying to join a multicast group using specific sources.

 

Here is my setup:

 

172.16.32.73 -> SG550XG mcast group 232.0.0.3

 

If I join the group in exclude mode without specifying a source list, I correctly receive the stream. Good.

If I join the group in exclude mode with the source address 172.16.32.73. I do not receive the stream. Good.

If I join the group in exclude mode with the source address 172.16.32.74. I do not receive the stream. Bad!

Finally, if a remove the address 172.16.32.74 from the exclude list, I recover the stream...

 

Does anyone have an idea of what I could have missed?

 

Regards,

Lionel

It seems that the behaviour of the SG550XG is very close to the recommandations of RFC 4604.

 

Therefore, the user should only use the INCLUDE filter mode with Cisco switches.

 

Does anyone can confirm that?
