The customer has a new building, a network refresh, or an acquisition that requires integrating a new site. They want a reference architecture — not a product pitch, not a features comparison — an architecture that they can hand to their network team and say &ldquo;build this.&rdquo;</p> <p>This post provides that reference architecture. It covers the standard 3-tier campus design with a security overlay, ISE node placement, firewall positioning, wireless security, Layer 2 hardening, 802.1X/MAB deployment, and SD-Access for modern campuses. At the end, there is a bill of materials template for a 500-user campus that SEs can adapt for proposals.</p>
