Using New-NcNetInterface against ONTAP 8.3.2 versus ONTAP 9.0

dkorns — Wed, 04 Jun 2025 15:27:24 GMT

This started out as WFA inquiry but I can reproduce the problem with just PowerShell. I am attempting to create a new LIF after creating a new SVM. The issue seems to have to do with Routing-Groups which were depricated in ONTAP 8.3 and even more so in ONTAP 9.0. The New-NcNetInterface cmdlet has a -RoutingGroup parameter which I'm leaving off. ONTAP 9.0 seems to want or need it but I have no idea what to give it since there are no routing-groups in ONTAP 9.0. ONTAP 8.3.2 seems to still support the concept (i.e.; Get-NcNetInterface will return the routing-group attribute of a LIF with a name like the old d192.168.0.0/24) but ONTAP 9.0 returns nothing ... hence I do not have anything to feed the -RoutingGroup parameter. Here is my testing. Am I missing something?

Hi @dkorns,

Does a route/gateway for that subnet exist on the SVM?

Thanks Andrew,

Good question, and no, there is no route (yet). I was thinking that would be done after creating the LIF since that is what some code Im looking at does (from a WFA command). But I re-tested creating a route before creating the LIF ... but it still complains about wanting a Routing-Group (or -RoutingGroup param). Maybe

Notice in the last command returning blank for RoutingGroupName ... which I think is ONTAP standard behaviour but can't udnerstand why New-NcNetInterface seems to require it. I'm probaly confused.

I tested your code with my ONTAP 9.0P1 system using ONTAP modules 4.1 and didn't encounter the error...

Maybe something else in the network configuration is missing?

Thanks Andrew ... could you do me a Get-NcNetRoute on that same system for comparison w/mine. I'm beginning to believe it could be a config issue. I had all this working w/8.3.2 and since I've introduced 9.0 in the mix I'm hitting this.

Also, on -NetMask versus -NetMaskLength ... I thought (possibly mistaken) -NetMaskLength was only for IPv6, so I set -NetMask (255.255.255.0) and either leave -NetMaskLength blank or pass 0 sometiems. I notice you just use -NetMaskLength 24 by itself ... in the IPv4 case does that get treated as 255.255.255.0?

Here is the Get-NcNetRoute output. Note that I created a dummy LIF using a subnet that previously did not exist on a port which did exist (so, I overloaded the port with more than one subnet).

PS C:\Users\asull> Get-NcNetRoute -Vserver NDC

0.0.0.0/0            172.16.10.1            20   NDC

Regarding "Netmask" vs "NetmaskLength", I have always used them interchangably with the difference being one is in IP notation, the other is an integer.

NetmaskLengh 24 == Netmask 255.255.255.0

Hi,

I'm new to this community.

I have the same problem in da script for creating a DR SVM.

As i analysed the difference between 8.3.2 and 9.0 is, that you don't need / can't use RoutingGroupName anymore.

so your script has to be aware witch ONTAP Version the controller runs.
