Port State and Operational State

There are two port attributes that are related and similar but have slightly different meanings: Port
State and Operational State (or Operational Status).
The following descriptions are based on normal individual ports. Many of the same concepts
apply to other objects that are modeled as ports in SR-OS such as PPP/IMA/MLFR multilink
bundles or APS groups but the show output descriptions for these objects should be consulted for
the details.
