Network Engineer: Migration Project from Shared Media to POE Switch Fabric for Office areas – 2005 – Assignment included challenges to bring the existing network infrastructure into a stable condition, identifying critical single points of failure and preparing plans for essential fix-up of design shortcomings.  It was also necessary to implement the new POE Switching Fabric for Cisco CallManager deployment.  Migration included using two Core 6509 COS based switches with 720 Management Modules for redundant links to 24 65xx IDF switches.  Both Core switches used redundant Gigabit links to each IDF as well as redundant links to connected 7200 routers for WAN access – redundancy was also implemented with HSRP on the 720’s integrated router (MSFC).  The routing protocol was EIGRP in the internal LAN to BGP to the ISP.
