Do you mean if PowerCLI has cmdlets to configure the networks on the VCSA appliance?
If that is what you ask, no there are no such cmdlets.

But there other ways to call the vami_config_net cli if that is what you mean.
The VCSA has the VMware Tools installed, so you could use Invoke-VMSCript.
Or use the  Posh-SSH module to use an SSH connection to the VCSA to execute said cli.

thanks LucD

Yep I mean the way 2 call VAMI  but I'm unsure about that. Can you provide me with some guidance?

Not sure what you mean by "guidance", it is either basic usage of the Invoke-VMScript cmdlet or basic usage of the Posh-SSH cmdlets.
For the latter, I have a short example in Use Posh-SSH instead of PuTTY

Please accept my apologies, I misspoke.

Can you give me a hand to add the bulk IP list?

Which vami_config_net command do you want to run through PowerCLI?

I just check vmware documentation regarding vami_config_net and i didn't find the information related to firewall so honestly not sure how to tacle this.

I suspect the only way in that case would be to edit the firewall.conf file (with sed).
That can be done with Invvoke-VMScript or through an SSH session.

then, I will try to learn about Invvoke-VMScript,  

Thank you
