I noticed that you can only add a cable ID (or circuit ID?) to a link when you
link two devices and their interfaces together.
Now, in a datacenter, it’s common to have many external cables from 3rd parties
coming in to your rack.
These cables or patches usually have some sort of a ID that identifies them and
separates them from other cables.
This ID is known by both us and the external third party.
Is there a way to attach a cable / circuit ID to an interface?
