Data Center- LAN Engineer

Location: Stamford, CT - Onsite

Duration: 6 Months

Fully onsite

Key Responsibilities

• Datacenter Upgrade & LAN Switch Replacement: Lead the migration from legacy Cisco 6500 (access-distribution-core) and Nexus 7000 (FabricPath) architectures to a modern VXLAN-based leaf-spine fabric in two data centers, replacing outdated equipment and multicast switches.
• VXLAN/EVPN Fabric Implementation: Configure and deploy VXLAN EVPN fabrics using Cisco NDFC, provisioning networks, VLANs, VRFs, and L3Outs, while ensuring high availability, redundancy, and integration with external networks.
• Multicast Switch Replacement & Troubleshooting: Execute the replacement of multicast switches, troubleshoot complex multicast issues, and ensure smooth functionality for applications and hosts in the multicast environment.
• Network Configuration & Management: Utilize Cisco NX-OS and Nexus 9000 series platforms to configure and manage network fabrics, including NVE interfaces, routing protocols (OSPF, BGP), and VXLAN components (VNI, VTEP).
• Troubleshooting & Operations: Diagnose and resolve Layer 2/3 and VXLAN-specific issues (e.g., MAC flaps, STP loops, VTEP reachability, BGP EVPN, multicast problems) using CLI, NDFC tools, and telemetry to monitor fabric health.
• Documentation & Change Management: Develop detailed implementation plans, rollback procedures, network diagrams, and configuration documentation, adhering to ITIL or organizational change control processes.
• Security & Segmentation: Implement VLAN segmentation, access control lists (ACLs), and VRF-based tenant separation to ensure secure and efficient network operations.
• Project Execution: Work independently to configure new hardware, prepare for network cutovers, and ensure minimal disruption during migrations, following design specifications.
• Long-Term Planning: Support future initiatives, including data center relocations and connecting new colocation facilities to existing data centers, ensuring scalability and design alignment.
