Archive switch configs with encryption, retention and least-privilege access while avoiding uncontrolled exposure of shared credentials or tokens. This action instead applies to Safe configuration archiving and secret handling. Configuration histories may contain secrets and management details, so backup security is part of switch operations. It does not directly resolve the controlling requirement. The targeted response is: Trace both traffic directions, routing next hops and LAG/ECMP distribution before blaming total switch fabric capacity. Scenario: An ECMP topology appears balanced by hop count but a route-policy difference sends most traffic to one WAN circuit.

Compare negotiated link speed and error counters to rule out physical bottlenecks before altering QoS or routing. This action instead applies to Duplex speed and physical error performance analysis.
