Esxi Link agregation

[Thib69230]

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...
