This reports the locale, per CucsFabricExternalLocale, of the discovered peer switch for this specific cabling record -- essentially whether it's internal to the UCS domain or an external network device. For this row, it's what distinguishes a peer that's part of the UCS chassis/fabric itself from a peer that's an outside data center switch, which changes how you'd troubleshoot a cabling discrepancy here. A locale value indicating 'external' confirms this specific cabling record describes a connection out to the customer's own network switch, not another UCS component.
