Service Port cannot be set to 0

[kevinreniers]

Environment

• Python version: 3.7
• NetBox version: 2.6.7

Steps to Reproduce

1. Try to set the port of a device service to 0

Expected Behavior

Client-side validation seems to allow this because the min value is set to 0.

Snippet:

<input type="number" name="port" value="0" min="0" class="form-control" required="" placeholder="Port number" id="id_port">

Server-side validation seems to restrict this min value to 1.

We would like to use "0" as a way to model "All Ports".

Observed Behavior

Form reloads and nothing happens.
Entering -1 also generates a client-side validation "value should be greater than or equal to 0".

Just out of interest, can you not resort to using a custom field instead of marking it as 0?

[kevinreniers]

Definitely as a workaround. I would prefer to limit the use of custom fields to a bare minimum if we can model it using standard fields, though.

We would like to use "0" as a way to model "All Ports".

This would not be a valid use of this field. This field reflects a specific port number, thus zero is not a valid value.

This is a bug only so far that the client side validation for the field specifies the minimum value as zero rather than one.

Thank you for the feedback. 😃

What would be your recommendation on modelling an F5 or Citrix virtual server that listens on all ports and is configured with 0 or *?

We have a few use cases like this that we would like to accurately and idiomatically use netbox as a source-of-truth for.

Since the port field is required, the recommendation of @ahmed-cader would not be entirely appropriate. Tagging, likewise, still forces an invalid value in the port field.
