    Dear,

    Is there any command or thing to do to make the traffic be split into the 2 radios? Here we setup as shown, but when we make traffic between 2 computer connected to the ETH1 on each IDU, we can that only the Radio1 traffic (similar when we use ETH3 of each modem). Sysconfig 2+0 has been had been applied successfully in both modem, and all license are OK.

    With only one computer on each side of the link in testing, you will only see the traffic go over one modem. You will need to have at least two computers on each side of the link for the MAC address hashing to work. At the simplest level, assume that all odd source MAC addresses go over modem one and even source MAC addresses go over modem two. The actual hashing method is more complex than this, but hopefully this example will help illustrate how it works.

    At the basic level, you need multiple MAC addresses on each side for the traffic to be split accordingly. The more MAC addresses that are present on each side, the more evenly traffic can be split between the two modems.

    You could probably simulate this with virtual machines (as long as the virtual networking is setup in a bridge mode where the unique MAC addresses come through) if you don't have multiple physical computers to test with.

    So is that means routing traffic, like we are trying to do (we are using GigaPRO to connect to internet fiber of our internet provider, 2 BGP router communication), can not benefit from this 2+0 capability?

    I'm told that the GigaPro will also do the hashing based on IP address, so it should work as long as you have multiple flows going across the link.
