Typical Use Cases

Campus and Enterprise WLAN

Aruba manuals guide high-density Wi‑Fi deployments for offices, education, and venues, including RF design, roaming optimization, and QoS for voice and collaboration apps. They detail SSID design, WPA3 transition strategies, and seamless onboarding with ClearPass.

Wired Access and Aggregation

For Aruba CX, manuals provide reference topologies using VSX for resiliency, configuration templates for access/aggregation, and consistent ACL, QoS, and segmentation policies. They also cover NetEdit/NAE automation and lifecycle management.

Cloud-Managed Operations

Aruba Central documentation walks through tenant setup, device onboarding, group hierarchies, site maps, firmware compliance, AI Insights, and alerting. It explains how to standardize configurations via templates and leverage API integrations for CI/CD.

Zero Trust and NAC

ClearPass manuals define policy design patterns: device profiling, role derivation, posture checks, and enforcement across wired, wireless, and VPN. They include recipes for integrating identity sources and issuing certificates for EAP‑TLS at scale.

SD‑Branch and WAN Optimization

Guides for SD‑Branch/EdgeConnect cover WAN overlays, application steering, dynamic path control, and security service chaining, improving performance and resilience for distributed sites.

Installation Highlights

Hardware

• AP and antenna installation with mounting kits and orientation guidance.
• Switch installation with airflow, noise, and thermal envelope requirements.
• Power and environmental specifications, rack safety, and grounding.

Software

• Image selection, compatible versions, and upgrade paths.
• Licensing models, subscription assignment, and entitlement checks.
• Initial configuration wizards and default security hardening steps.

Configuration Essentials

Wireless

• SSID creation with PSK, 802.1X, or captive portal.
• Role-based access with dynamic VLAN or user roles.
• Bandwidth contracts, application visibility, and airtime fairness.

Switching

• VLAN and trunk setup with native VLAN and tagging consistency.
• L3 routing with OSPF/BGP, ECMP, and VRF segmentation.
• Security: DHCP snooping, DAI, IP Source Guard, and control‑plane policing.

Policy and Access

• ClearPass services for wired/wireless, device profiling, and onboarding.
• Certificate issuance, CRLs/OCSP, and supplicant configuration.
