I think there is an (unsupported) way to pull directly that info. If you send me the output of:



show route forwarding-table multicast destination <your_group_address> extensive
show chassis fpc pic-status



I can tell you the next steps.

ok this is not exactly the same as in IOS, this is an ACL with logging....



hence not so immediate for any mcast flow...



Any other idea ?

You probably need a filter like this:

 

configure

set firewall family inet filter myFilter term myFlow from source-address 1.2.3.4/32

set firewall family inet filter myFilter term myFlow from source-address 224.1.2.3/32

set firewall family inet filter myFilter term myFlow then count myFlowCount

set firewall family inet filter myFilter term myFlow then accept

set firewall family inet filter myFilter term Rest then accept

set forwarding-options family inet filter input myFilter

commit and-quit

 

show firewall filter myFilter
