Arista Networks, a global leader in cloud and artificial intelligence (AI) networking solutions, announced a major expansion of its Cognitive Campus portfolio with the launch of Massive Scale Campus Mobility. This comprehensive update includes the introduction of Arista VESPA (Virtual Ethernet Segment with Proxy ARP) for wireless LAN (WLAN) mobility, enhancements to its autonomous AI framework AVA® (Autonomous Virtual Assist), and new campus switching platforms designed for challenging outdoor and industrial environments.
Arista’s latest innovations aim to address the scaling and operational complexities enterprises face as campuses grow in size, device density, and performance demands. These new capabilities extend the company’s cloud-native network operating system EOS® (Extensible Operating System) across broader mobility use cases and rugged deployments.
Next-Generation Campus Mobility with Arista VESPA
The newly introduced Arista VESPA reimagines campus Wi-Fi mobility by applying data-center–grade architectural principles to wireless networks. This approach enables organizations to support massive roaming domains with over 500,000 clients, providing resilient connectivity with sub-second failover and eliminating the need for traditional controller-based architectures.
“As one of the largest public universities, the ASU Wi-Fi environment has to support a vast and dynamic campus community. In transitioning to Arista’s controller-less Wi-Fi, we’ve partnered with them to help shape and validate the development of Arista’s VESPA architecture a standards-based approach designed to provide a seamless wireless roaming domain that improves connectivity across the university,” said Jorge De Cossio, Senior Director, Digital Infrastructure, Enterprise Technology for Arizona State University.

Expanded AI Operations with AVA
Arista continues to evolve its AI-driven network automation with expanded capabilities in AVA. Built on the EOS platform and using NetDL® as a unified data repository, AVA now offers an agentic AI framework that elevates the operational intelligence of campus networks. These enhancements help deliver proactive insights, automated issue detection, and deeper event correlation across wired, wireless, data center, and security domains.
Key AVA capabilities include:
• Multi-domain Event Correlation to identify root causes spanning multiple network layers.
• Agentic Conversational and Troubleshooting with advanced, context-aware dialogue.
• Continuous Monitoring and Automated Root Cause Analysis for proactive incident handling.
Ruggedized Platforms for Industrial and Outdoor Environments
To support demanding edge and outdoor scenarios, Arista also announced two new ruggedized switches the 710HXP-28TXH and 710HXP-20TNH. Both models are engineered to withstand harsh conditions such as extreme temperatures, vibration, and shock, making them ideal for industrial settings, outdoor Wi-Fi 7 access points, and high-power security cameras.
• The 20-port Din Rail switch (IP50 rating) provides versatile connectivity in compact form factors.
• The 1RU 24-port switch (IP30 rating) delivers robust performance with multi-gigabit and 90W PoE support.
These rugged platforms run on Arista EOS and integrate with CloudVision for consistent, unified management across all network environments.
All software enhancements and new hardware platforms are anticipated to be generally available by Q1 2026.
