SUMMARY:

• Responsible for configuring small to medium LAN environments.
• Most infrastructure environments consisted of Cisco systems technologies.
• Duties include, setting up more efficient routing and advanced technology concepts such as MPLS, EIGRP, and Dmvpn; switching concepts such as setting up Vlans, STP, and VLSM; as well as security practices for servers, switches, and routers alike.
• Skill set also includes tcp/ip, port addressing, and subnetting; specifically finding better subnets so that address space is used in the most effective way.
• I work frequently with CUCM (Cisco Unified Call Manager) more specifically the configuration of voice gateways, IP phones, Cisco collaboration applications such as Cisco Spark and Jabber/Webex, LDAP and active directory integration and performance Qos meeting IP SLA’s.
• I am Familiar with T1 PRI circuits and how they in corporate into a Voice environment.
• I am able to demonstrate excellent cable management and LAN closet cleanup.
• I am familiar with wireless networks, Cisco 2500/5500 series controllers, and AP’s/Airtight as well as 802.11 schemes.
• In almost all of these scenario’s, the configurations were completed in a virtual or remote environment which has increased my familiarity with hosting software such as VMware, Hyper - V, PuTTy connection manager, and Cisco CLI analyzer.
• In addition to the configuration aspect, I have worked with several network monitoring softwares such as Solarwinds, Cisco prime, and Netbrain some which I have installed personally and incorporated into an enterprise network.
• With that, I have applied Tacacs, ACS server, ISE server configs to provide user and server access to network devices along with the necessary ACL’s and Nat translations needed to allow access.
• Tasked with creating detailed documentation including rack diagrams, physical/logical Visio diagrams.
• I have also used packet tracer software like Wireshark/Dynamips to identify network and call latency.
• I have experience implementing application firewall access rules and object zones mostly using Cisco ASA 5500 series and ASDM GUI manager.
• I have worked with F5 Big IP load balance networks, round robin one arm and two arm configurations, Pool, Node, and VIP interface creation.
• Worked with industry professionals such as Presidio, Netcraftsmen, and CDW on various intensive network development projects.
