This guide gives you a copy-and-paste Aruba CX configuration for NAC / 802.1X (aruba cx 802.1x port access nac), plus the rationale behind each line and a free SafeCadence analyzer that scores your existing config against this same best-practice template.
What this snippet does
This Aruba CX template implements Aruba CX 802.1X port-access with MAC fallback + role. It’s been distilled from vendor documentation, NIST SP 800-41 / SP 800-53, and CISA hardening guidance — and battle-tested by SafeCadence on real production engagements.

Why this matters
- Prevents lateral movement by hardening port + management plane.
- Stops common attacks: ARP spoofing, rogue DHCP, BGP hijack, OSPF poisoning.
- Aligns with CIS Benchmarks for Cisco IOS / Juniper / Arista.
How to validate your config
Copy your existing Aruba CX running-config and paste it into the matching SafeCadence analyzer. The analyzer will tell you exactly which best-practice checks pass, which fail, and the per-finding fix:
