Best Practice for managing Network Transfer Points

[novanormy]

Greetings from Austria,

I am a Network Engineer at a small ISP. Like virtual Hardware on a VM, I would like to keep Track of how much Bandwith I have assinged to a Customer Port. Usually there are more small Services on a Port. Right now I have a Port (let‘s call it Interface 1/1/1), and my Services as a Sub-Interface (Lets call them 1/1/1.1 to 1/1/1.100). My Main Port has an assigned Speed of 10Gbits, which is the „Maximum Allowed Allocations“ I can provide on this Interface. Every little Sub-Interface have a variety of 4 to 200 Mbits.

Is there a way to see on the Device, how much I have already allocated? if not, is there a Workaround (Script) where i could check this?
