Confirming a reboot after creating the VLAN does not reveal the new interface dropdown menu in Interface: Assignments. Not sure how to create a functional VLAN from scratch.

VLAN created:


No menu option to add interface:

[Disregard - after 2 reboots it worked.]

I can delete the VLAN from Interface: Assignments but it remains in the sidebar and the underlying Interfaces: Devices: VLAN cannot be deleted because "This VLAN cannot be deleted because it is assigned as an interface." I assume this is related to the fact that I manually added the VLAN using the + in Interface: Assignments.
Is there a way I can bypass the UI and tear this down via SSH?

Disregard - after 2 reboots it worked.

Theres an issue with the interface cache right now it should be fixed soon in 26.7.2 (the assignment page was rewritten). Best reboot once and it should show in the assignment dropdown in the meantime.

Got it. Thanks a lot!

What do you mean by "I tried creating the interface manually"?

You'd want to create it inter Interfaces -> Devices -> VLAN, then assign it, then configure it...

I clicked + in the Interfaces:Assignments page since it was not offered as one to add per the linked instructions.

[this never occurs]

I'm giving up on pfSense and started to install and configure OPNsense today!

I am running the current version 26.7.1 and am trying to set up my first VLAN. There have been recent changes to the interface so instructions for setting up VLANs don't exactly match what I'm seeing today. When I follow directions like OPNsense lab it states "Step 2: Assign interfaces - Interfaces → Assignments. Each new VLAN appears in the "new interface" dropdown — add it, then it shows up as OPT1/OPT2/OPT3" but this never occurs. I tried creating the interface manually and assigning DHCP to the interface but I am not able to connect my client to the VLAN.

Here is the output of ifconfig -a

While on the VLAN interface settings I have a Static IPv4 configuration set to 192.168.14.1/24 but when I go to Interfaces > Overview there is no entry for IPv4 on the VLAN interface.

Any advice is very appreciated!
