In my case, each Ethernet interface has its own unique MAC address. Dave On Mon, May 11, 2009 at 4:28 PM, Hector Herrera <hectorherrera () gmail com>wrote:

Ifbothinterfaces are on the same subnet, the OS sees the same router (gateway) address on both interfaces, and the results are sub-optimal ... around50%packet loss.packet loss is probably due to the network switch having to re-learn the location of the MAC address constantly as it sees packets on two or more ports with the same MAC address (think STP loops). If your network stack and network device (switch) supports LACP, then you can have multiple connections between a host and a network device. That is a very easy way to increase capacity and add redundancy. That is how all of our VMWare ESX 3.5i servers are connected. Hector
