This value reports the locale (for example internal versus external) scope of the physical Fibre Channel endpoint representing one FC-facing port on the fabric interconnect, together with the neighbor device it discovers on the wire. An administrator distinguishing chassis-internal connections from external network cabling checks locale on this PhysFcEp instance, since internal and external Fibre Channel endpoints are cabled and diagnosed differently. For example, a locale marked internal on this PhysFcEp instance tells the operator not to go looking for an external cable when troubleshooting it.
