Add Tenant to Cable Model

[nbogle]

NetBox version

v2.11.8

Feature type

New functionality

Proposed functionality

I would like to see the ability to assign cables in Netbox to a tenant.

This would involve adding a link between the tenancy.tenant model and the dcim.Cable model.

Use case

I use Netbox in a datacenter setting, and I would like to be able to assign cross connections (in netbox as cables) to tenants, so you can see all cross connects a tenant might have, or what cables were put in for which client.

Database changes

I don't believe this would require any database changes

External dependencies

No.

Strongly agree. We are a service provider with many leased lines (dark and lit) dedicated to customers and peers. Knowing at the cable level what's assigned to specific tenants would be very helpful for planning and auditing.

This would be a welcome add to associate and track cross connects to tenants.

Somewhat related to #5140.

I'm not sure it makes sense to associate a cable with a tenant directly, rather than inferring from the tenant which owns either of its endpoints. Though that raises the question: if a cable connects devices belong to two different tenants, which one owns the cable?

[bellwood]

I would proffer whomever installs the cable would be the owner. That could either be the A tenant, the Z tenant or perhaps the facility making the connection.

[bellwood]

I suppose, too, for our intended purposes of tracking cross connects, those could be entered as circuits, which do support tenants.

I'm not really opposed to adding a tenant relationship on the cable model. I think it's perhaps suboptimal, but as discussed in #5140 there are other issues with filtering by tenancy of related objects.
