DHCP snooping requires to be enabled globally before it will function correctly. If it is not enabled globally, even if enabled on VLAN interfaces, DHCP snooping will not work.

Enabling authorized DHCP servers (A) or trusted interfaces (B) is necessary but only after global enabling.

Enabling DHCP snooping on VLAN (C) is not sufficient without global enablement.

Therefore, enabling DHCP snooping globally is the first step to activate the feature.

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.

For an availability-sensitive WLAN deployment, the appropriate AOS-CX capabilities are Quick PoE and Always-on PoE . They address two different switch power-transition conditions and together minimize interruption to PoE-powered APs.

Always-on PoE maintains PoE delivery to already powered devices during a soft reboot , including scheduled switch reboots and firmware upgrade operations. Consequently, an AP-615 does not unnecessarily lose electrical power and perform a complete hardware boot merely because the CX switch ' s operating system is restarting. HPE Aruba specifically identifies this capability on the CX 6300 as part of its high-availability PoE functionality. Aruba Networks

Quick PoE addresses a cold reboot/power-up condition. HPE Aruba defines it as allowing the PSE to restore power to connected powered devices shortly after the switch powers up, rather than waiting for the complete network operating system initialization sequence. Aruba Networks Developer Hub

Using both features therefore covers both major restart scenarios: Always-on PoE preserves existing power across software restarts, while Quick PoE accelerates AP power restoration following a cold startup. For hospital WLANs supporting critical endpoints, this combination provides the highest AP power availability among the listed choices.

The LACP state event Actor state: ALFNCD, Partner state: ASFNCD indicates that the LACP negotiation between the local (actor) and peer (partner) is successful with all flags matching and no errors.

ALFNCD and ASFNCD are standard LACP states indicating Active, Long timeout, Aggregation capable, Not synchronized, Collecting, and Distributing flags set as expected.

Also, the log shows the LACP rate is set to slow, which is the default.

Thus, the output shows the LAG 253 has a matching LACP configuration with its peer.
