Scale 22.12.2 - Static IP for 1 interface?

[dust_bro]

I feel like I missing something obvious here. I have an onboard NIC I use for Management, and a 10G pci card I use for data. I'd like to use DHCP for the internal, and set the 10G to a static IP.
When I uncheck the DHCP setting on the 10G card, it also unchecks the DHCP setting for my internal card. I can't seem to be able to set them to different values.
Don't remember this happening on Core.

does no one else have issues with this? You're able to set a static IP for one NIC and DHCP for another?

On CORE yes, so you should be able to do so on SCALE as well.

Resource - Multiple network interfaces on a single subnet

We've had a number of people over the years bring up the topic of multiple network interfaces on a single subnet. Often done by Windows administrators or storage admins, where it works to varying degrees, this is sadly not proper IP networking...

This isn't supported. The purpose of DHCP is actually to allow bootstrapping of your NAS into your network, and once you can reach it via either the VGA console UI or the network webGUI, you really should configure it for a static IP address. Infrastructure systems like NAS that establish long-lived TCP sessions should not be subjected to DHCP lease renewals, which cause connection drops.

DHCP is allowed on one single interface on the system. The default configuration enables it on all interfaces, but only because the NAS has no idea what interface you intend to use. DHCP on multiple interfaces introduces configuration ambiguity into the system, as argued previously with various DHCP zealots on these forums. The GUI attempts to enforce the one-single-interface rule for DHCP; attempting to set more than one interface to DHCP, or attempting to mix static IP configuration along with DHCP will appropriately be prevented by the GUI.
