Aruba Mobility Controllers

Why do you need mobility controllers?

Average enterprise campus has 500+ access points. Managing each AP separately means configuration chaos and security gaps. Without central controller, no consistent policies, seamless roaming, or visibility.

Aruba Mobility Controllers are a family of WLAN controllers that centralize management, security, and services for enterprise wireless networks. They support up to 8192 APs with integrated layer 7 firewall.

How does it work?

Centralized Architecture

Controller as the brain of Wi-Fi network:

• Central configuration of all APs
• Unified policy enforcement
• Traffic aggregation and tunnel termination
• Single point of management

Integrated Security

Security built into architecture:

• Policy Enforcement Firewall (PEF) - L7 firewall
• User-based access control
• Role-based policies
• Deep packet inspection

RF Intelligence

Intelligent RF optimization:

• Adaptive Radio Management (ARM)
• Dynamic channel and power adjustment
• Interference mitigation
• Seamless roaming without packet loss

Main Features

Management

• Central AP configuration
• Template-based deployment
• Firmware management
• Real-time monitoring

Security

• WPA3 Enterprise
• 802.1X authentication
• Guest access isolation
• Encrypted control plane

Mobility

• Seamless L2/L3 roaming
• Fast BSS Transition (802.11r)
• Voice-grade roaming
• Location tracking

High Availability

• Controller clustering
• N+1 redundancy
• Stateful failover
• Zero downtime upgrades

Product Series

7000 Series: Controllers for small and medium deployments (up to 2048 APs)

9000 Series: Enterprise controllers for large campuses (up to 8192 APs)

FAQ

Do I need controller for each location? Not always. Controllers support APs over WAN with appropriate latency. Large locations may have local controllers.

What’s the difference between 7000 and 9000 series? 7000 series up to 2048 APs for smaller deployments. 9000 series up to 8192 APs for large campuses.

Do controllers work with Aruba Central? Yes. Central manages controllers and APs, providing cloud visibility and AIOps.

How does licensing work? Per AP. Foundation or Advanced licenses depending on required features.

Can I use virtual controller? Yes. VMC (Virtual Mobility Controller) runs on Hyper-V, KVM, and in cloud.

How does seamless roaming work? Fast BSS Transition (802.11r) and user context stored on controller ensure roaming without connection loss.

Is controller required for Aruba APs? No. Aruba also offers APs in Instant mode (without controller) and APs managed only by Central.

How does high availability work? Clustering with automatic failover. Controllers synchronize state, ensuring service continuity.

What security certifications? Common Criteria, FIPS 140-2, GDPR, HIPAA, PCI DSS compliance.

What about support? HPE Foundation Care. nFlo as a partner offers design, deployment, and support.
