Hi,
I'm having some trouble with Esxi (6.7) and LAG.
Perhaps I don't understand NIC Teaming on Esxi ...
- I set up the vswitch with 2 active NIC (2x 1Gb) and route based on IP hash.
- I create two virtual machines attached to this vswitch.
- On my switch, I set up the interfaces as static LAG.
- I do some bandwidth test with "iperf" between two physical machines (each with 1 Gb/s ethernet connection) and both VM.
- I do other test with "iperf" between 3-4 machines (each with 1 Gb/s ethernet connection) and both VM.
I hope to get results close to 2 Gb/s, but in reality I only get a result close to 1 Gb/s.
Where am i wrong ?
How to get a real LAG ?
Hi,
As you are aware that LACP is only available in distributed switches.
Also, check the below KB for the requirements for link aggregation for ESXi.

Thanks.
After several tests :
- static lag with Alcatel Omniswitch : no ok 1 Gb/s
- static lacp with huawei S1720 : no ok 1 Gb/s
- trunk port with HPE Aruba 2540 : ok 2 Gb/s
It seems that not all switch can support LAG for esxi...
