Custom TCP/IP Stack - uneditable in vShpere web ui

[cal70]

Hoping for some guidance / help.  Right now have used the command line to setup a second TCP/IP stack, hoping to have a second mgmt connection.  I have successfully:

1. created the TCP/IP stack

2. created vmk nic

3. made the associations in web ui,

4. able to view the above vmk, TCP/IP stack.

     i. NONE of the static setting in custom stack are editable, from what I have been able to learn, is I need to 'enable' or setup vmkernel port?  (HOW, I don't know.)

I can 'edit' the stack in the gui.  I have successfully set the management setting for the vmk nic, but the last thing ... that I think I need to do is set up the custom TCP/IP stack, but I can't.  I'd be ok with doing it vi esxcli command but I can't find anything on how.  HELP if you can pls

Cheers!!

Really looking for some help .... as a newbie, I'm trying to setup a lap to learn, so anything appreciated.  Any of the setting in this red box, CAN NOT SET them, maybe I can via esxcli?  OR set the GUI right?

Hi

In the vSphere Web Client, customization of a VMkernel port can be defined during the creation of the VMkernel adapter.

Please read this post of Duncan Epping and also this one too

However I tested it again to be ensure in my lab... For ESXi version 6.0 and 6.7 (that I deployed them before) when you connect directly to the ESXi host with the vsphere web client, regardless of Default TCP/IP stack you cannot modify none of the TCP/IP stacks. Then I back to the vCenter server and change the provisioning stack's IPv4 gateway, and come again to the ESXi. While that field is shown editable, but I couldn't change the parameter here. (prompt failed to update ...)

Thank you.. for the reply.  So if I understand you tested it, and was not able to modify any of the settings?  So I'm guessing that the custom TCP/IP stack is not an option I can use.  I thought I was close with the esxcli options, but I can't seem to find the command / method of how to configure the stack from the command line.   Do you have any suggestions I might be able to try

Always you have a little more changing and customization operations in the CLI/Shell environment (especially via the using the esxcfg / esxcli) in front of vsphere client/ web client, but after all you should know exactly each one of TCP/IP stacks are used for which operation:

1. Default for management traffic
2. vMotion for live migration and vMotion
3. Provisioning for cold migration, snapshot and cloning ...
