linux machine setup when capturing traffic

[shelley_wang]

I am monitoring 2 or more source interfaces which are running 1G traffic on each interface. Destination is 10G interface.

There are 2 kinds of traffic running through the source interfaces: icmp and regular IP traffic. I am only interested in capturing icmp traffic. How can I achieve my goal?

I don’t have any vlan traffic at all. Router is c6500.

         source (1G)                    destination (10G)

------------------------- Router --------------------------------------Linux

                                    |   source (1G)                        

                                    |

thx,

Jingyi
