Hi,

Ik think you should try this one. On each enabled multicast interface type the

command ip mroute-cache. With "show interface stat" you can check how many packets are hit by the cache and the processor,

I did it at very begining of first time, but it seens did not work , when i type

"show interface sta" it indicate large amount of packets being process by CPU, that is why i wonder if multicast cache work,
