Resolution

As soon as the interface/s is removed from the List Resources, the Orion database will delete the record on 'Interfaces' record.
However, its historical data in 'InterfaceTraffic*' tables still exist.
When that interface/s is re-added on the List Resources, it will create new record this time with a different InterfaceID. So even if the historical data is still there, Orion web console won't display the stored information from the old InterfaceID.
On the next schedule of Database Maintenance (by default every 2:15AM), the Orion Database will delete all the historical data from 'InterfaceTraffic*' tables for the old InterfaceID because it will be classified as a stale data as the InterfaceID no longer exists in the 'Interfaces' table.
