Confidential

Onsite Technician

Responsibilities:

• Member of a team of professionals responsible for installations, administration/service requests and escalation support/ticket, site - surveys, configurations, maintenance, management, and troubleshooting resolution and analysis.
• Technologies in network environment include but not limited to routers, switches, Confidential firewalls, voice, video, Confidential and related technologies supporting a global component based automation and services organization.
• 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 further 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 secure access and EXEC command interpreter interval to the console and vty ports.
• Created and managed 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. Utilized VLAN Spanning-Tree in conjunction with PVST+ for compatibility between Confidential and Juniper switches and for root bridge assignment.
• 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 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 Confidential area to allow injection of external routes into the area and propagation into the OSPF domain.
• Implemented backup and recovery of Confidential IOS Images. Perform password recovery on Confidential IOS routers/switches and a Juniper EX2200 Series switch to restore administrative access. Backup and Restore startup-comfit 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 Confidential events.

Confidential

Responsibilities:

• Implement an IPSec Site-to-Site VPN between the Confidential ASA5505 at small office location and Confidential 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, transform set using esp-des esp-sha-hmac to 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 Confidential 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 Confidential ASA 5505 using a web browser. Prepare the Confidential 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.
