I also tried with "10.5.5.8.243" and the vlan1 interface is not present. So it looks like a bug with the N3248 image that start somewhere after the 10.5.3.2.89 version and it still present on the most recent available version.
You mention you are using an N3248TE appliance. Could you test on (a) another appliance such as an S5212 for example. To help rule out if it could be platform specific. or (b) another version of OS10 to help rule out if it could be version specific.
Also, it could be interesting to see if errors are reported when creating new vlans (before assigning interfaces to those vlans).
Thank you for your answer. I have this issue with a fresh OS10 image, without any other configuration.
For (b), I tried with 10.5.6.0.47 and 10.5.6.2.110, but I can try with an older one if you want.
for (a), I tried with the "DellOS10S5248F-10.5.6.2.110-1" image and it works. I don't have any issues when I assign a VLAN to an interface.
I don't have this error message when I create the VLAN, I can do
OS10# configure terminal OS10(config)# interface vlan 10 OS10(conf-if-vl-10)# ip address 192.168.10.1/24 OS10(conf-if-vl-10)# end OS10# show ip interface brief Interface Name IP-Address OK Method Status Protocol ========================================================================================= Ethernet 1/1/1 unassigned NO unset up down [all the other ethernet interfaces] Ethernet 1/1/52 unassigned NO unset up down Management 1/1/1 unassigned NO DHCP up down Vlan 10 192.168.10.1/24 NO manual up down OS10#
But now I see the difference with the S5248F, there is indeed no Vlan 1 interface display here on the N3248TE. I also try to change the default vlan, but I encountered the same error.
ok, that's very informative. So with another platform we have no problem (i.e. the S5248). So the issue is only seen on the N3248 appliance.
I just spun up a test on my local GNS3 setup ... it's got an earlier N3248 appliance running 10.5.3.2 ... and it allowed to create a new vlan and assign to an interface without an error
So that would seem to suggest it's an issue on some versions of the N3248 appliance. Perhaps one workaround could be to test using an earlier version and see if also works for you.
In my case I ran with OS10.5.3.2.89 as it just happened to be the version on that particular GNS3 server
Hello, was trying 10.5.6.6 yesterday and was same issue. As no resolution was posted here, I had to spent few hours trying to understand the issue.
So it seems to be caused by having ports ethernet 1/1/53 and 1/1/54 in default vlan 1.
My working solution to fix this was going into system bash, edit directly startup.xml and remove ports 1/1/53 and 1/1/54 from l2 vlan1. After reboot of the appliance, vlan 1 is appearing and all works as expected.

I can confirm it works on "10.5.3.2.89".
I also tried with "10.5.5.8.243" and the vlan1 interface is not present. So it looks like a bug with the N3248 image that start somewhere after the 10.5.3.2.89 version and it still present on the most recent available version.

Hi Darkanite,
I've seen a similar error occur on S4148 platforms and it related to restoring a config file onto a different switch profile

I don't have this error message when I create the VLAN, I can do

@swieku How did you figure the problematic ports ?
