Hello,
When I configure n IGMP filter profile, as you can see from the output
below, if you put a perm/then range, this shows up in the config. If you
do a deny/then range, this DOES NOT show up in the config, so this copuld be
quite mislining to someone looking at the config.
It all works fine, as I have tested tring doing amn IGMP Join within the
specified denied range, and the route does not see the IGMP join as the
c3550 blocks it.
Can anyone confirm that they have seen the saem error?
Many thx indeed,
Ken
