 Configuring :

• Configure routing protocols (Static, EIGRP, OSPF, BGP, PBR) for enterprise-grade scalability.
• Implement switching protocols (VLAN, VTP, STP/RSTP, HSRP, VRRP, Port-channels) for redundancy and traffic optimization.
• Set up firewall rules, NAT, ACLs, zones, and VPN technologies (IPSec, DMVPN, GRE, GlobalProtect).
• Deploy wireless controllers (Cisco 9800, 2500 WLC) and access points (1600i, 1700i, 2600i).
• Configure load balancing solutions (Citrix NetScaler) for application delivery.
• Integrate WAN technologies (MPLS, SilverPeak SD-WAN) into enterprise networks.

·Change Management:

• Plan, document, and execute configuration changes with rollback strategies.
• Follow ITIL-aligned change management processes to minimize downtime and risk.
• Maintain version-controlled configuration repositories for reproducibility.
• Validate changes using automation scripts and monitoring tools (Zenoss, Grafana, Splunk, PagerDuty).
• Collaborate with cross-functional teams to schedule and approve changes.

 Troubleshooting:

• Diagnose routing and switching issues using packet analyzers (Wireshark, Ethereal).
• Resolve firewall and VPN connectivity problems across Palo Alto, Juniper, and Cisco platforms.
• Troubleshoot wireless coverage, interference, and controller/AP issues.
• Identify and fix load balancing misconfigurations impacting application performance.
• Perform root cause analysis using syslog, IP-SLA, and monitoring dashboards.
• Provide rapid escalation support for critical outages and performance degradations.

 TAC Engagement:

• Open and manage TAC cases with Cisco, Palo Alto, Juniper, and other vendors.
• Share logs, configs, and packet captures for deep‑dive troubleshooting.
• Track case progress and ensure timely resolution of escalated issues.

 RMA Management:

• Identify faulty hardware and initiate RMA requests with vendors.
• Coordinate logistics for replacement devices, ensuring minimal service disruption.
• Validate new hardware post‑deployment and update inventory records.

 Documentation:

• Create detailed Visio diagrams for network topology and workflows.
• Maintain MS Office documentation for configuration standards, change logs, and troubleshooting guides.
• Record lessons learned from incidents to improve future troubleshooting efficiency.
