Hi Andrelst, Thad and all, I used mode=1 and the martian sources went away. Thanks Andrelst.
I did some more googling and found this link http://www.linuxfoundation.org/en/Net:Bonding. It says mode=1 is preferred for high availability on a multiple switch topology while mode=0 for high throughput on a single switch topology. It is also a good reading about bonding. About the martian sources on mode=0, I suspect it is due to the fact I had a multiple switch topology and according to the link -- "This mode is the only mode that will permit a single TCP/IP connection to stripe traffic across multiple interfaces. It is therefore the only mode that will allow a single TCP/IP stream to utilize more than one interface's worth of throughput. This comes at a cost, however: the striping often results in peer systems receiving packets out of order, causing TCP/IP's congestion control system to kick in, often by retransmitting segments." Just want to rant, a "service network restart" did not change bonding modes. A reboot was necessary. Comments are still welcome on the topic and always open to suggestions. Cheers!

But FYI to the list forum here, it does not give you load balancing (active-active) and high throughput on the Network. -- regards, Andre | http://www.varon.ca On Wed, Nov 19, 2008 at 12:06 AM, thad <[EMAIL PROTECTED]> wrote: > Lily Tomlin - "The trouble with the rat race is that even if you win, > you're still a rat." > >> If your switch has LACP or 802.3ad or "etherchannel" in cisco >> terminology support, mode=4 is the best. > > From my previous work we set mode=1 it works fine with rhel.
