I want have 2Gbps bandwidth (peer to peer) with 2 1Gbps NIC. It's on HP MicroServer Gen8, 2 on board NICs.

I have bind 2 NIC teaming with LACP, dynamic load balance, but one interface has large traffic, other has not traffic. (NIC0 has traffic NIC1 has no traffic, and I exchaged NIC0 and NIC1 in swich hub, NIC1 has traffic, and NIC0 no)

traffic

the switch hub configuration (h3c s5008pv2) below:

GigabitEthernet1/0/4 is the port which seems not work(but status is UP, and NIC status in win2012 is ACTIVE)

Bridge-Aggregation3 is the bond port(GigaEth1/0/3 & GigaEth1/0/4).

If I'm understanding you correctly, there is always activity to the same switch port regardless of which NIC it's plugged in to? This rather suggests the problem is with the switch.

You mention that you've set the server up to use LACP - this needs to be configured on the switch as well as on the server.

I believe Windows also supports "Static Teaming" and "Switch Independent" settings for NIC teaming. If you cannot configure your switch to use LACP then consider using one of these modes as appropriate.

  • tks, switch (h3c s5008) has set bridge aggregration with lacp. – user219031 Jan 1 '17 at 15:50
  • if set to static aggregation, same problem. – user219031 Jan 1 '17 at 15:56

You will never get 2Gbps bandwith peer to peer with LACP, you will only get 2Gbps combined bandwith (theoretically) with multiple clients accessing the server at the same time.

  • I have tried transfer large file from two different computer to this server at the same time, each one have 1gbps max, but only1gbps on this server – user219031 Jan 1 '17 at 15:47
