AOS-CX is a modern, database-driven operating system, but it is built with extensive backward compatibility to ensure it fits into established enterprise ecosystems.
CLI (Command Line Interface) (Option A): This is the most traditional form of switch management. AOS-CX provides a robust CLI accessible via Console, Telnet, or SSH. While the syntax is " industry-standard " (similar to Cisco or older ArubaOS-Switch), it remains a " legacy " pillar that almost all existing management systems (like Rancid, SolarWinds, or custom scripts) use for configuration and state collection.
SNMP (Simple Network Management Protocol) (Option E): SNMP is the universal " legacy " language for network monitoring. AOS-CX supports SNMP v1, v2c, and v3. Legacy Management Systems (NMS) rely on SNMP MIBs (Management Information Bases) to pull statistics about port utilization, temperature, and errors.
Modern vs. Legacy:
REST API (Option B): This is a modern, programmable interface where every command in the switch can be executed via a JSON-based web call. Legacy systems typically do not support this.
NAE (Option C): The Network Analytics Engine is unique to AOS-CX and uses Python scripts for local monitoring. This is a " Next-Gen " feature.
HTTPS (Option D): While web interfaces have been around a while, the modern AOS-CX Web UI is a sophisticated tool built on top of the REST API, and it is generally considered a primary management method for the " Modern " era rather than a " Legacy Management System " integration point like SNMP.
