static LACP result for standard VSS portid load balance and active-standby nics.

I have an ESXi 6.7 host and it has one active nic and one standby nic in VSS, load-balance is portid.

and I create a port-channel with these two nic members in Switch for testing static LACP.

In this scenario, I ping the testbed from some other hosts. However, some hosts cannot ping it and some hosts can ping it. Even they are all in same L2 environment.

If I shutdown one port on switch, the issue is gone.

I think the load-balance configuration both on switch and hosts should be the root cause.

Is it possible to keep the two ports port-channel on switch  and make the host  online?

Need Experts' help explain its workflow.

Thanks in advance

First of all, LACP is not supported with a standard switch. You can only do a static LAG and if using it must use the IP hash algorithm.

Thanks daphnissov.   I know that iphash with two active vmnics are required. Just want to get some details about wrong configuration.
