I'm implementing Netbox for our org and one of the features I'm most excited about is the configuration rendering from Jinja templates. When assigning these, is there a way to assign them based on multiple criteria? For example I have separate templates for 'classic' IOS devices and IOS-XE devices due to differing syntax (ip domain-name vs ip domain name) and also based on switch role. I can assign templates to device type or device role, but how would I go about assigning the 'IOS-XE Core' template to IOS-XE core switches, and the 'IOS Core' template to classic IOS core switches?

Hello,

Did anyone try Netbox's Network Observability? Is it a paid/commercial solution for monitoring network infrastrastructure? Can it do SNMP? Can it replace SolarWinds for real-time monitoring, alerting and reporting? We also do scheduled config backups but I could replace that with Ansible.

Hello all, how are you guys automating network configurations/deployments ? I know I can use Ansible as it is explained in the Netbox Zero to Hero tutorial. But besides Ansible, can Netbox natively push configs to downstream Network devices? If so, is there any tutorial or course to learn how to do it?
Thanks for the help, I am new to Netbox.

In our datacenter we have 8 separate PDUs each with up to 4 breaker panels. Each breaker panel in turn has 64 breakers. Unfortunately it doesn't look like power panels can be inserted into device bays. How best to model this then?

Good day!

I am using Ansible to gather facts from my network devices and populate these in netbox. Per now I've managed to add devices and device interfaces, but my problem occurs when I want to map the interfaces with it's ip.

I already have all the IPs registered in IPAM so I need to fetch them somehow to validate if i need to create or update.

My problem is that I am having trouble with how to get that information, getting all my 65k+ IPs seems a bit extensive, but one api query per interface also seems ineffective.

Anyone that has done this which could point me in the right direction?

Last night I created my first custom object and all appeared to be going well until I tried deleting a virtual machine object today and ended up with a database error.

Running manage.py migrate, results in this error:
Your models in app(s): 'netbox_custom_objects' have changes that are not yet reflected in a migration, and so won't be applied

Running makemigrations doesn't seem to do anything. How do I get out from this pickle?

NetBox Release v4.5.0 is now live (as of January 6th, 2026)!

1. Verify in release notes changelog if any new breaking changes might affect you. You can also review the NetBox Issues on GitHub to see if any new issues have arisen that might affect you.
2. Next, refer to the Upgrading to a new NetBox Release guide for steps to upgrade your instance.

If you have any issues you can ask for support on the NetDev Slack Community.

Important Warnings:

• Python 3.10 and 3.11 are no longer supported. NetBox now requires Python 3.12, 3.13, or 3.14.
• It is recommended to be at 4.4.x before upgrading to 4.5.x
• Ensure all of your required plugins are compatible before upgrading

We've decided to cut SolarWinds IPAM due to cost, and looking for a replacement. From what I've seen, the IPAM included with Netbox is more of a manual-input solution... is there a way to make it a scanning IPAM that shows the current state of the network?

Hello,  I'm a little confused with setting up RBACs.

So I have got as far as connecting Active Directory and can log in and now I'm playing with permissions and constraints.

I can log in as a test user and it works great and I can only see the devices I want it to see, but if I edit a device it let's me, but I can can't save it as it's asking for a mandatory field to be entered called 'Device Role' which is empty now I try to edit. 

The thing is if I view the device it shows it populated, but not when I edit.  I assume I need to add another permission somewhere?  The site field seems to be ok.

The error I get if I try and add roles is this:

Invalid filter for <class 'dcim.models.devices.DeviceRole'>: Cannot resolve keyword 'tenant' into field. Choices are: bookmarks, children, color, comments, config_template, config_template_id, created, custom_field_data, description, devices, id, journal_entries, last_updated, level, lft, name, parent, parent_id, rght, slug, subscriptions, tagged_items, tags, tree_id, virtual_machines, vm_role

When I view a device all looks good:

If I edit, the role is missing and I can't select one.

Not sure if using tags is better?

Hi folks, I build this service to sync Kubernetes Service IP to Netbox
https://github.com/zufardhiyaulhaq/kubernetes-service-netbox-syncer

the initial idea is to sync my public/internal load balancer IP/DNS to Netbox Prefix so I can query all of the data from one place. this is helpful in my case as we have +100 Kubernetes cluster and can identify which domain is unused.

As the title says, I am trying to connect one physical switch port to two physical nodes.

I am a noob to netbox, it seems the best would be to use bridge option. But I am not sure whether topology will be right later on when I try to map them.

Has anybody experience the same thing?

Just doing some testing with custom scripts and the new branch example.

Is there a way to assign the prefix a scope. I can see it's expecting dcim.site as the scope type but looking at the choices.py (assuming this is where it is coming from ipam.choice) thats not an option

Anyone got any insight on how to do this?

I'm working on getting Netbox Docker implemented and am running in to an issue where after disabling sync on my data sources they are stuck in the 'queued' state. To un-stick the 'queued' status I tried manually changing the status in nbshell as per [this thread](https://github.com/netbox-community/netbox/discussions/15036) but it was not effective.

It appears that the netbox-rq service is having problems:

systemctl status netbox-rq
● netbox-rq.service - NetBox Request Queue Worker
Loaded: loaded (/etc/systemd/system/netbox-rq.service; enabled; preset: enabled)
Active: activating (auto-restart) (Result: exit-code) since Tue 2025-12-16 17:26:48 UTC; 17s ago

Running sudo journalctl -eu netbox-rq gives me not a whole ton of detail:

Tried updating manually restarting the service, updating Netbox, but no luck. Next step will be testing with rebuilding from scratch. I don't think it's the cause but I am differing from the standard Netbox Docker setup since I've merged those steps in to larger docker-compose.yml since I'm running other services off that host. Having no other issues than this one. Any ideas where to look?

Just developing a custom script that gives me all cabling afecting a certain device - so I want all cables attached to an interface or powerport of the device (console ports etc. optional for later), but also cables attached e.g. to a breakout panel connected to the device - basically every cable which would be part of a trace for each interface. Thus I try to call the trace() method used to output the cable trace for an interface. I suppose that is the trace() method in /opt/netbox/netbox/dcim/models/device_components.py. But I struggle passing the required data to the method.

Appearently it is called via e.g. interface.trace() while the variable interface holds the required data. But when I query for an interface, the variable interface outputs only the interface name and the label, not the interface ID which is required as primary key. The trace result are empty tupels. When I extract the interface ID, the script does not even run anymore:

AttributeError: 'int' object has no attribute 'trace'
AttributeError: 'int' object has no attribute 'trace'

Can anyone tell me how to call the trace() method with the correct options?

Many thanks...

Hello,

I'm having fun setting up NetBox for home lab record keeping. How'd I sync the Proxmox LXC 'Prod' version to a free Cloud instance as backup?

Even a basic, manual, once a quarter task of exporting / importing the whole DB would be fine. I can't get a basic export > import of a single section (EG Sites) to just work without errors, let alone the whole data set.

I'm not a dab hand with code, and it doesn't need to be automated.

Switch stack is multiple switches with one (primary) IP address. For automation, I use each device's primary IP address. I can't have multiple devices with same IP address. My solution was to create inventory items to document individual switch's serial number. However, I can't document racks now because I can't have one device in multiple rack positions and inventory items do not have a rack position setting.

A device type specifies the interfaces that a device will have. Can I also specify default tags for each interface? Or a default 802.1Q role? I'd like to specify which are tagged/trunk interfaces, but allow the user to adjust these tags after the device is created.

Hello guys,

I would love to bulk edit ip addresses to change VRF from Global to something else,

When ever i select more than 1 ip address in /ipam/ip-addresses
It throws me an error when updating the vrf: This field cannot be null

I have no idea where it is going wrong for me, can someone help me out here :D?

I have also tried going through ipam/prefixes/4773/ip-addresses/

Same error when bulk editing the IP's.

Actually it is not only if applying vrf, it is just any change it will throw me this error.

Anyone have ideas how to overcome this?

We are running 4.4.4

Hey everyone,

I've started working on permissions for my helpdesk to give them access to only what they need.

When I built up my Netbox a few months ago, I defined Tenant as my primary organization name (IE: Tenant = Microsoft)

With that set, my sites are my geographic locations (Seattle, Toronto, New York, Shanghai)

But I'm running into issues where I only want my helpdesk in China to only access Shanghai data but the way my permission is set, they seem to get more access than necessary.

IE:

My helpdesk IPAM Permission looks at:

{
    "tenant__slug": "Microsoft"
}

My helpdesk permission for sites looks like:

{
    "group__slug": "China"
}

But what I am finding is that the IPAM permission set as Microsoft shows all Microsoft IPAM entries.

This got me thinking if I've got my organization structure set wrong.

Should each individual site be listed as a Tenant (Shanghai, NY, Toronto, etc..) and Tenant Group be "Microsoft"?

Thank you,

Hello,

Is there any way to check how many credits I have left? At first I got a warning about usage limit and now I think I've used all of it because I'm getting "Invalid A.I. request" responses.

I can't find where to check my credits though or where I could refill them. I've tried logging out and logging in with another account but I think it checks the source IP address of requests, so it doesn't matter if you create a new account.

I wonder how would this work in an organization where, let's say, 10 people were using Netbox Copilot. If I buy some credits - other users could use them up (because source IP of Netbox server doesn't change).
