Richard Achmatowicz commented on AS7-4540:
------------------------------------------

This issue affects the running of the AS7 testsuite in the QA lab, in which only one distinct multicast address is available per node.

> The expected behaviour is that as long as the ports are distinct, we should be able to use the same mcast address for both udp and diagnostics.
