Can I remove an interface's MTU value with a REST PATCH?

[grantmortenson-experity]

Hello, I am trying to use the REST API to update several interfaces that were improperly configured with an MTU value when they should not have any value assigned. I am struggling to find a way to remove the MTU value with the PATCH method. I tried setting the value to 0, but got an input validation error instead.

Is it possible to clear the MTU value in this way or do I need to use PUT? I am using NetboxPS as a wrapper around the API (I'm new to using REST APIs so this seemed like a good stepping stone to further my learning) and it currently doesn't use the PUT method in any cmdlets.

Any advice you can offer is appreciated. Thanks!

Have you tried PATCH with null as the value?

This is what I see if I query an interface with no MTU set:

      "mtu": null,

Yes, that works. I'll have to see if I can extend the PowerShell module to allow null values. Thanks for helping me figure this out!
