This value reports the locale (for example internal versus external) scope of the physical Ethernet endpoint representing one Ethernet-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 PhysEtherEp instance, since internal and external Ethernet endpoints are cabled and diagnosed differently. For example, a locale marked internal on this PhysEtherEp instance tells the operator not to go looking for an external cable when troubleshooting it.
