Network Engineer Resume


  • IT Professional with over 7 years of experience in implementation/deployments, administration/service requests, Tier 2/3 escalation support/ticket resolution, change management, analysis, and troubleshooting various network technologies which includes proficiency in routing, routing protocols, switching, security, firewalls, voice, wireless and data center technologies.
  • Implemented trunk ports to control 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.
  • Implemented port-profiles as part of the NX-OS command structure that allows for configuration of multiple ports and port-types via inherited configurations applied to reduce errors and allows for better configuration readability.
  • Implement a virtual version of 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.
  • Implemented secure privileged administrative access to the Cisco IOS system.
  • Enabled the encryption of system passwords to prevent unauthorized users access to passwords in the system configuration.
  • Implement secure access to the console and vty ports, and set the interval that the EXEC command interpreter waits until user input is detected on the Console and vty ports. Also, configure the console and vty ports log messaging to not interfere with active device configuration.
  • Implement VLAN Trunking Protocol to reduce administrative overhead.
  • Enable secure sharing of VLAN information to prevent the introduction of rogue devices from affecting the VLAN database. Shutdown unused switchports following Layer 2 security best practices.
  • Create and manage Local VLANs based on department function, and configure ports with static VLAN assignment, static 802.1Q trunks, and dynamic ISL trunking using PAgP for layer 2 forwarding.

  • Prevent neighbor adjacencies from being formed as well as the sending and receiving of routing updates on unnecessary interfaces. Implement EIGRP MD5 Message Authentication between sites to prevent unauthorized insertion of routes into the domain. Implement manual EIGRP route summarization to reduce routing protocol demand on CPU resources, memory, and bandwidth used to maintain the routing table.
  • Implement OSPF routing with multiple areas for networks between sites. Implement totally stubby areas to lower the system resource utilization of routing devices for the network. Implement NSSA area to allow injection of external routes into the area and propagation into the OSPF domain.
  • Implement backup and recovery of Cisco IOS Images. Perform password recovery on Cisco IOS routers/switches and a Juniper EX2200 Series switch to restore administrative access. Backup and Restore startup-comfig file for disaster recovery.
  • Configured and verified internal BGP peering using directly connected networks and loopbacks by using an interior gateway protocol (OSPF) to provide routing information.
  • Configured and verified external/internal BGP peering using directly connected networks, loopbacks and ebgp-multihop, and Route Reflector with debugging diagnostic commands to monitor BGP events.
  • Configured MPLS manually and using automatic configuration via OSPF.
  • Configured virtual routing and forwarding (VRF) instances with route-targets and route descriptors.
  • Configured MP-BGP to send VRF traffic in an MPLS VPN.
  • Redistributed provider edge networks into MP-BGP and verified end-to-end connectivity over the MPLS VPN.
  • Implement an IPSec Site-to-Site VPN between the Cisco ASA5505 at small office location and Cisco 1841 ISR with a security IOS image at the main office. Implementation of the VPN includes the following configurations: Internet Key Exchange Policy using DES and SHA for encryption and authentication, access-lists to define VPN traffic, transform set using esp-des esp-sha-hmac to define how the traffic is protected, crypto-map to associate the previously configured elements to a peer, and application of the crypto map to appropriate interface or VPN endpoint.
  • Implementation of Zone-Based Policy Firewall on the Cisco 1841 ISR with the following components: three zones, class-maps specifying traffic that must have policy applied as it crosses a zone-pair, policy maps to apply action to the class-maps’ traffic, zone-pairs, and application of policy to zone pairs.
  • Implement a Clientless SSL VPN (WebVPN) to allow users to establish a secure, remote-access VPN tunnel to the Cisco ASA 5505 using a web browser. Prepare the Cisco ASA with necessary configurations to self-signed certificate generation. Generate a general purpose RSA key-pair for certificate authority identification, configure certificate authority trustpoint for the WebVPN using self enrollment, and configure CA trustpoint interface association.
  • Configure Syslog on the Cisco ASA 5505 with logging to a host and internal buffer. Forward all logging to an internal Syslog server for monitoring and management. Configure and manage Syslog output generation using custom message lists. Implement FTP backup of internal buffer when it is exceeded.
  • Implement Basic Threat-Detection, Advanced TCP Intercept, and Scanning Threat-Detection. Simulate attacks on network to manage threat-detection rates and verify Syslog generation.
  • Utilize Cisco ASA 5505 Modular Policy Frame-Work to configure and manage layer 3/4 interface service policies, apply inspection and connection limits to services, apply inspection and QoS policing to HTTP traffic. Configure HTTP inspection policy to block restricted sites and file downloads.
  • Configuration and troubleshooting of high availability pairs of F5 BIG-IP devices via a GUI and CLI to provide a virtual web server utilizing round-robin selection to balance traffic on several web servers.
  • Implemented local voice network using Cisco 2811 ISR (VoIP) with a Cisco Unity Express Network Module (NM-CUE), Cisco Communications Manager Express, Cisco 3550 Switch with Power-over-Ethernet. Created and managed Data and Voice VLANs, and configure ports with static VLAN assignment and 802.1Q trunks for layer 2 forwarding.
