[j-nsp] Command to see multicast packet size

[Antonio Sanchez-Monge]

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 ?

Tks

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

Hi
I saw it but no info is found related to the average pkt size...
