How do we determine that a port is in use in a "Ports in use" report from Spectrum SRM?

Issue/Introduction
Sometimes it is reported that ports are in use, however the ports appear as idle in the report from Spectrum Report Manager (SRM).

Resolution
Among the many attributes we read for each port, we read the Internal_Link_Status attribute (0x10f1b) and the ifInOctets attribute (0x10e41).
The Internal_Link_Status attribute determines the value of the port_link_status field in the interfacemodel table.
The newly read value of ifInOctets gets compared to the last known ifInOctets value for that interface (by reading the current ifInOctets field of the interfacemodel table in the SRM db).
If the value has increased, we then update the dateLastSignificantTraffic field of the interfacemodel table to today's date.
Spectrum then writes the latest value of ifInOctets to the ifInOctets field of the interfacemodel table.
