Load balancing via IP HASH without LACP

Hi there,

I wondering if I can setup a standard vSwitch with IP Hash without LACP.

My customer only have an Essential Plus licence, therefore I cannot setup a distributed vSwitch and LACP protocol on my physical switch.

If I deploy a standard vSwitch with two network cards, IP Hash load balanced and on my physical switch I set the port in trunk mode but without LACP (because it's not supported on standard vSwitch), is there a realy load balanced traffic between my two NIC or it's on active passif mode and thus 1 NIC is only active ?

Thanks in advance for your answer

Best regards

This should help: Route Based on IP Hash

Thank you for your answer

This document says " ESXi hosts support only 802.3ad link aggregation in Static mode . You can only use a static Etherchannel with vSphere Standard Switches. LACP is not supported"

We have Aruba physical switches so as I understand, it's impossible to configure load balancing with IP Hash ?

If it doesn't support static LAGs, then no.

It does support static LAGs

We will configure LACP on physical switch and test (with standard vSwitch) if it's working

You can't use LACP as that's a dynamic LAG which requires a vDS. Only static LAGs are supported with a standard switch.

I can configure dynamic LACP trunk, static LACP trunk or static trunk (non protocol) on my physical switch
