SUMMARY:

• An IT professional with over 4 years of technical experience and an Confidential veteran in configuration, engineering, installation, implementation, administration and troubleshooting of various LAN/WAN technologies for small to corporate enterprise environments which includes proficiency in routing, switching, security (mostly firewalls), wireless, voice and data center technologies.
• Implement trunk ports and implement granular control of VLANs and VXLANs using NX - OS to ensure virtual and flexible subnets that can extend further across the network infrastructure than previous generation of switches.
• Implement port-profiles as part of the NX-OS command structure that allows for configuration of multiple ports and port-types via inherited configurations applied via a single command that reduces administrative error and allows for better configuration readability.
• Implement a virtual version of Nexus: Nexus1000v into VMWare to extend Nexus capabilities directly adjacent to virtual machines so that they benefit from Cisco switching capabilities and network topology consistency ensuring VMs maintain their subnet/VLAN relationships during failover.
• Implement secure privileged administrative access to the Cisco IOS system. Enable the encryption of system passwords to prevent unauthorized users access to passwords in the system configuration.

• Implement password recovery on the Cisco 5510 ASA.
• Implement a local voice network with the following network elements: Cisco 2811 ISR (VoIP) with a Cisco Unity Express Network Module (NM-CUE) installed, Cisco Communications Manager Express, a standard Cisco 3550 Switch, and a Cisco 3550 switch with Power-over-Ethernet. Create and manage Data and Voice VLANs, and configure ports with static VLAN assignment and 802.1Q trunks for layer 2 forwarding.
