Hey Hani

Thanks for your reply

What I'm firstly trying to achieve is greater network throughput in my LAN
for data transfer to from my NAS's
>From what I have read for modes balance-rr balance-tlb or balance-alb
doesn't require switch support?
But I am happy to do 802.3ad as my switch supports it

what I have is
in my debian 7.0 64bit pc I am running 1x intel pro 1000 mt pci-e but have
ordered a PT model
I have 2x netgear readynas pro's both with bonding enabled also
also running this all through a tp link sg3424 which supports LAG

my problem is I don't seem to be able to get the 2x intel pro 1000 ports to
be bonded properly
I was using ifenslave on debian 64bit
although messages, ifconfig bond0 /proc seems to show fine
I have turned on LAG support in the tp link switch for those ports but
doesn't seem to help
since then I have disabled the on board nic just to be sure
mostly been following this

(bonding in Linux is new to me so I may of made a mistake)

Thanks Paul
