Thank you for all the responses.
This interface is connected to one of our vendor switch which provides the
multicast feed. The traffic on this feed could be as high as 30
megabits/second. I increased the input queue to 500 because I was getting
so many drops with the default 75 queues. Since this interface only
receives the feeds so the vendor set the switch port to 100/half ( and they
won't do 100/full ). I noticed that I have mroute-cache disabled on the
interface that's why all the packets are process switched. I will enable
the mroute-cache on the interface and let you guys know the results.
Here are some configs and show commands if you guys are interesting in it.
