Hello jcpark,

Here are the links to a couple of guides for configuring LACP on unity ports.

Hello jcpark,

Which model switches are you using?

Hello jcpark,

You can configure your unity using LACP and it should not have an issue.  Here is a link to a Dell EMC Networking with Isilon Front-End Deployment and Best Practices Guide which explains what all needs to be done. https://dell.to/3UmFY3f

Thank you for answer

What I want to ask is whether there is any problem with communication even if the port used by Unity is set to LACP when the switch interworking setting is LACP rather than VLT.

If the interlink is LACP, I wonder if that protocol communication is possible even if the port used by Unity is configured as LACP.

As far as I know, VLT was able to communicate between LACP.

Thank you for answer

Model is S4148.

The customer wants to continue using the previously configured Inter-link as LACP.

Is there a recommended Unity network configuration when configuring with LACP rather than switch-to-switch VLT?

For example, as mentioned above, when configuring Inter-link with LACP, I asked if it should be configured with FSN.

Thanks.
