Hello !

            We use a lot of multicast on the LAN. The throughputs of multicast traffics seem to vary a lot during the day and ghost operation are not reliable on the LAN.  We use Catalyst 6500 with Sup720  PIM- Sparce-dense mode. During the day, Cpu, memory and link utilization doesn’t seem to be busy enough to affect performance.  At night Ghost are very fast so the problem point to my switch.  Maybe I am not monitoring the right variable on my Catalyst 6500 to link this performance issue with a certain chokepoint in my Catalyst.

 

            Many CCIE came to solve our multicast/Ghost problem but nobody ever succeeded. If anybody can suggest item I might have overlook or I should investigate let me know off line. We have validated the configuration with auto-RP and pim-sparce-dense mode.

 

Thanks,
