Manage Cisco ACI/APIC fabrics, including spine and leaf configurations and policy-based networking; configure vPC domains in ACI and traditional NX-OS environments.
Configure and maintain EIGRP, OSPF, and BGP, including redistribution, route summarization, tagging, and convergence optimization.
Implement and troubleshoot QoS policies to support application performance.
Configure redundancy and failover technologies, including STP, port channels/LACP, HSRP, StackWise Virtual, BFD, and dual-homing designs.
Optimize IPv4 and IPv6 coexistence and transitions, including NAT64 and dual-stack deployments.
Deploy and manage copper and fiber cabling; work with patch panels, extend POTS lines for modem-based out-of-band access, and use cable-testing tools.
Select and validate optics and transceivers for data center interconnects.
Apply ACLs, prefix lists, and route maps for security, routing protocol functions, redistribution, and QoS.
Support compliance and change-management processes through thorough documentation and adherence to standards.
Use Ansible and Linux for network automation and orchestration.
Use Cisco Nexus Dashboard, Insights, and Data Broker for network visibility and optimization.
Manage SNMP-based monitoring platforms and troubleshoot with tools such as Wireshark.
Use physical TAPs and SPAN technology for network visibility and monitoring.
Collaborate with data center teams on virtualization technologies, including VMware vSphere, VRFs, and hypervisors, with exposure to Nutanix AHV as the organization transitions toward hyperconverged infrastructure.
Document designs, configurations, and changes; produce diagrams and technical documentation.
Support ServiceNow ticketing and ITSM workflows and contribute to change management.
