Let me know different configuration option so i can try with the same.....As i don't have full time access to this secnario i may not give full output...So pls tell me diffent config options.......thanks
When I see that someone is configuring load sharing to do per packet load balancing I am concerned about the impact of out of order packets. While I do not know for sure if this is the cause of your problem I would suggest that you investigate this possibility.
Is it possible to get some protocol analyzer (Sniffer/Ethereal/etc) to capture and analyze this traffic? If so run the transfer and look for retransmissions/lost packets.
If it is not possible to do a packet capture there are a couple of things that might be helpful in the investigation on the router. Configure the load interval on all 4 interfaces to the minimum value. Then I would suggest that you transfer the same file several times (once with both links active, once with only one link, and once with only the other link). I would suggest doing clear interface counters before each transfer, and then show interface commands several times while each transfer is being done, and then at the end of each transfer. I would look at the total number of packets transferred and check to see if the total packets was the same when both links are used as the number of packets when a single link is used. If the number of packets is larger when both links are used then it is probably a sign of packet loss and retransmission.
I would also look at the show interface output done while that transfer is being done on the two single links. I would look at the number of bytes per second being transferred. Are the same number of bytes being transfer over link 1 as are transferred over link 2? If there is much difference in number of bytes per second there there is some performance difference between the links and this could lead to out of order packets, packet loss, packet retransmission, and worse performance with both links are in use.
