I think it might be letting you know its bonded. Try deactiving one of the two NIC's and pinging again.

Also, if you do a service network restart you should see an indication concerning bonding.

bonding run correct,
if I remove one cable all traffic flow to the second interface and yes, I have a bond0 interface.

You have also to make the switch work.
On Cisco switches it's called "etherchannel"-feature which have to be activated on the ports your server plugs in.
