Responsibilities

• Deploy and configure Aruba 6400 core switches (VSX, VLAN routing, trunk links to Cisco Nexus 7Ks).
• Implement Aruba 6300M switches for a 100% wireless environment on testing floors, then scale to all floors.
• Configure VLANs, default routes to Granite SDWAN, and Active-Gateway (VSX) for redundancy and routing between VLANs.
• Ensure compatibility and interoperability with existing Cisco Nexus 7Ks, verifying routing and transit VLAN functionality.
