Responsibilities

• Monitoring & Incident Response: Monitor network health and respond to alerts/incidents; triage issues, restore service, and coordinate escalations with providers and internal teams.

• Troubleshooting (LAN/WAN Route/Switch): Diagnose and resolve routing and switching issues (OSPF/BGP/EIGRP, HSRP/VRRP, STP, VLANs, QoS) across campus and WAN environments using logs, telemetry, and packet captures.

• Cisco Catalyst & Nexus Operations: Support and troubleshoot Cisco Catalyst and Nexus switching platforms, including port provisioning, VLAN/trunk configuration, STP consistency, vPC (where applicable), and hardware break/fix coordination.

• Software Upgrades: Plan and execute switch software upgrades and patching for Catalyst and Nexus platforms (pre-checks, compatibility review, maintenance window execution, post-checks/validation, and back-out planning) in accordance with change control.

• Cisco ACI Operations: Support day-to-day ACI fabric operations (tenants, VRFs, bridge domains, EPGs, contracts), troubleshoot endpoint/contract issues, and assist with controlled changes and upgrades.

• SD-WAN Operations: Administer SD-WAN policies, segmentation, DIA, application-aware routing, and failover; troubleshoot site connectivity and performance problems and coordinate ISP circuit remediation.

• Azure Network Operations: Support Azure networking components (VNets/subnets, NSGs, UDRs, Azure Firewall, VPN Gateway/ExpressRoute, Private Link/Endpoints, load balancers, DNS) and participate in troubleshooting hybrid connectivity issues.

• Hybrid Connectivity Support: Operate and troubleshoot on-prem to Azure connectivity (ExpressRoute/VPN, BGP, routing/propagation, redundancy); validate routes and failover during maintenance and incident scenarios.

• Change Execution: Implement standard network changes (adds/moves/changes, policy updates, route changes, segmentation changes) following change control, with back-out plans and post-change validation.

• Problem Management: Perform root-cause analysis, document findings, and drive preventative actions (config hardening, standards, monitoring improvements, and recurring-issue elimination).

• Documentation: Maintain accurate diagrams, runbooks, configuration standards, and knowledge articles; contribute to operational readiness and handoff procedures.

• Automation & Scripting (as applicable): Create or use scripts to reduce toil (data collection, config validation, report generation) using tools such as Python/PowerShell/Ansible and vendor APIs.

• After-hours Support: Participate in on-call rotation and scheduled maintenance windows as needed.
