Comprehensive Detailed Explanation:
To prevent man-in-the-middle attacks based on Layer 2 (Ethernet) addressing, enabling ARP inspection in the VLAN context is recommended. ARP inspection validates ARP packets and ensures only legitimate ARP responses are forwarded.
Enabling ARP inspection at VLAN level allows granular control.
Interface-level or global context is less typical or supported for ARP inspection on Aruba CX switches.
