PROFESSIONAL EXPERIENCE:

LAN/WAN Professional Network Engineer

Confidential

Responsibilities:

• Technical operations responsibilities including acting as technical lead for network implementation/deployments, handling high level change requests and tier 2/3 escalation support with focus on providing root cause analysis.
• Member of a team responsible for onsite LAN/WAN support, deployment, and configurations of routers, switches, wireless, firewalls, and related LAN/WAN technologies at both data center, corporate, and branch locations following SLA requirements and following mandated policies and procedures.
• Specific Technologies handled include but not limited to Cisco ISRs/ASRs; Cisco Catalyst/Nexus Switches Cisco ASAs; Juniper EXs; F5 Big-IP Version 11.6.0; Cisco Unified Communications Manager Express Version; Cisco Unity Express Versions; Cisco Wireless LAN Controller; Cisco Aironet 11x Access Points; Palo Alto (PAN) Firewalls, Nagios, Solar Winds Orion, Cacti, Wireshark, VMware vSphere ESXi, PBX, Hubs, Repeaters, Patch Panels and Patch Cord.
• Member of a team responsible for overall maintenance and support of the organization including administration, escalation support, troubleshooting and documentation based on mandated policies and procedures along with industry compliances and preparing updates/reports to supervisors and executive management.
• Implemented VLAN Trunking Protocol to reduce administrative overhead and to control VLANs and VXLANs using NX-OS to ensure virtual and flexible subnets that extend farther across the network than previous generation of switches.
• Implemented port-profiles in NX-OS for multiple ports and port-types to reduce errors and improve readability.
• Enabled encryption of system passwords and privileged administration to prevent unauthorized IOS user access.
• Implemented frame-relay point-to-point and multipoint WAN links between sites to establish connectivity between four sites. Established frame-relay point-to-point connections between three sites to create a full mesh network. Implemented hub and spoke network between three sites with the main office as the hub for redundant connections.
• Implemented EIGRP routing for point-to-point and Non-Broadcast Multi-Access networks. Prevented neighbor adjacencies forming and sending/receiving routing updates on unnecessary interfaces. Implemented EIGRP MD5 between sites to prevent unauthorized insertion of routes into the domain. Implemented manual EIGRP route summarization to reduce demand on CPU resources, memory, and bandwidth used to maintain the routing tables.
• Implemented multiple-area OSPF routing and totally stubby areas to lower the system resource utilization of devices. Implemented NSSA area to allow injection of external routes into the area and propagation into the OSPF domain.
• Implemented 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-commit file for the DR.
• Configured e/iBGP peering using directly connected networks and loopbacks with OSPF, eBGP multihop, and Route Reflectors to provide routing information with debugging diagnostic commands to monitor BGP events.

Confidential

Responsibilities:

• Implemented an IPSec Site-to-Site VPN between the Cisco ASA 5505 at small office location and Cisco 1841 ISR with a Confidential IOS image at the main office.
• Implemented VPNs for IKE Policy using DES and SHA for encryption and authentication, access-lists to define VPN traffic, a transform set using esp-des esp-sha-hmac for traffic protection, crypto map to configured elements to a peer, and application of the crypto map to appropriate interface or VPN endpoint.
• Implemented of Zone-Based Policy Firewall on the Cisco 1841 ISR for three zones, applying class-maps as traffic 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. Prepared the Cisco ASA with necessary configurations for self-signed generation. Generated a general-purpose RSA key-pair for authority identification. Configured authority trustpoint for the WebVPN using self-enrollment, and configured CA trustpoint interface association.
• Utilized Cisco ASA 5505 Modular Policy Frame-Work to configure and manage layer 3/4 interface service policies, applied inspection and connection limits to services, and applied inspection and QoS policing to HTTP traffic. Configured HTTP inspection policy to block restricted sites and file downloads.

Confidential

Responsibilities:

• 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 POE. Created and managed Data and Voice VLANs, and configured ports with static VLAN assignment and 802.1Q trunks for layer 2 forwarding. Configured edge ports for fast-transitioning into the forwarding state to fix workstation startup connectivity delays.
• Implemented Unity Voicemail on the Cisco Unity Express Network Module. Configured dial-peer on a Cisco 2811 ISR to define attributes of packet voice network connections to Cisco Unity Express Network Module. Enabled call forwarding on busy/no answer. Implemented Message Waiting Indicators and Voicemail access via SMTP.
• Implemented a wireless network infrastructure providing access to wired LANs to increase mobility and productivity on Cisco WLC 2106, Cisco 3550 switch, Cisco 1130AG and 1121G series APs. Created wireless LANs and configure interface association, Confidential parameters, and radios used. Managed the wireless network through the WLC web GUI.
