This one of the methods used to provide fail over for network traffic.
From our BladeSystem support staff
"This is just a “redundancy mechanism” that is part of the HP Teaming driver.Not trying to over simply things but here it goes. NIC A and NIC B are teamed together. NIC A is receiving frames okay, NIC B has not received any frames.Teaming driver sends “Test Frame” out NIC A, sets timers and waits for NIC B to receive it. This is repeated a few times.If NIC B still has not received a frame after a few intervals, it is determined the RX (Receive) Path to this NIC is broken, thus NIC is marked as “Receive Path Validation” and is removed as an Active member of the team. This is a good thing because we don’t want a NIC in the team that can’t hear… So…either there is a problem with that NIC receiving frames (fix it) or there is a problem in the Teaming driver detecting “false” RX Path failures.Either way the recommendation is never to disable it as a solution to the problem.
