On my machine, I have assigned ip addresses for two interfaces which are connected through a cable. They are connected with 10G ports.

When i tried to ping the two addresses, ping was not working. later on my analysis i found that the arp request is not resolved.

The arp table entry for that ip is shown incomplete.

I could not understand why the arp request is not resolved.

Please help me with this..

Here is the arp request and tcpdump logs

arp

Have you ran a packet capture with tcpdump or wireshark, if so, providing the output of that would be most useful. Is iptables configured? Can you show us the configuration of this also please? How can you configured the IPs, can you show us the configuration of this also? Lots more information would help! –  jwbensley Oct 30 '12 at 13:45
    
Did you doublecheck the cabling/speed/half/full duplex setting? –  Kamil Šrot Oct 30 '12 at 16:10

Have still the same opinion - check wiring. The arp entry with MAC showing "incomplete" means nothing - it'll show up for any local IP you try to reach even if it's not set on any computer in your local net –  Kamil Šrot Oct 31 '12 at 8:08
