Abstract
A method for identifying a failed network interface card in a system having two NICs configured as a team includes the steps of transmitting a first data packet from the first NIC to a third NIC, wherein the third NIC is not a member of the team, and transmitting a second data packet from the first NIC to the second NIC or from the second NIC to the third NIC, depending on whether the third NIC responds to the transmission of the first data packet. One advantage of the disclosed method is that it specifically identifies which NIC within the team has failed, which is something that cannot be determined by simply exchanging packets between the two NICs.
