At Ericsson India Private Limited, I manage Cisco Catalyst 9200, 9300, and 9500 switches and provide L1/L2 support for enterprise network connectivity.
I configure and troubleshoot VLANs, trunking, EtherChannel, STP, and HSRP to support segmentation, redundancy, and network stability.
I also configure FortiGate policies and Site-to-Site and Client/Remote Access VPNs, and support URL and Web Filtering. During upgrades, I manage firmware and configuration backups with rollback procedures.
I investigate switch and firewall incidents, coordinate with Cisco TAC and OEM vendors, and provide 24x7 SLA-driven production support. I hold a B.Tech in CSE (Data Science) and a CCNA certification.
