Technologies in a network environment including but routers, switches, security firewalls, voice, wireless, monitoring tools, load balancers, and technologies. • Working with third party vendors for new project implementations related to network support.• Developed and documented network diagrams and procedures. Migration of network segments from flat to hierarchical architecture. Settings of the networking devices (Cisco Router, switches) co-coordinating with the system/Network administrator during implementation. • Create and manage Local VLANs based on department function, and configure ports with static VLAN assignment, static 802.1Q trunks for layer two forwarding. Configure edge ports for fast transitioning into the forwarding state to fix workstation startup connectivity delays. Modify spanning tree parameters for root bridge assignment. Modify channel load balancing method. • Managing health check of Network devices this involves upgrading IOS on every quarter after checking the vulnerability of IOS and reviewing the configuration. • Determine problem areas for future improvement to reduce incidents.• Prepared infrastructure for AP registration on the same subnet as management VLAN and AP registration on a different subnet. Testing and validating new solutions in the lab before deploying. • Implemented traffic filters using Standard and Extended ACL, Distribute-Lists, and Route Maps. • Deployed 95 Palo Alto firewalls devices to locations, ranging from PA 200 - PA5060 series.
