  Rewarded Hi-coins: 0 (problem resolved)

hello, our customer encountered a problem, please help us to solve it.
our customer connect two s5720 switches through eth-trunk which bond with three 1G links, but the customer reported that the bandwidth couldn't reach 3G when doing the test. He inspected the physical links and replaced the links, but the problem still the same.

appreciate for any suggestions, thanks.

@user_3445655 hi,
that's normal, when the traffic is from one end user to another user, the traffic will be hashed to one interface, so the rate doesn't exceed the physical link bandwidth.
if you want to hash the traffic to all the links, you could adjust the hash algorythm to per packet rather than per flow. in that scenario, the packets may be out-of-order.
