-Responsible for porting, testing & supporting the software for serial communication (12in1) cards in Cisco’s 7600 Series of routers. The software was ported from legacy SIP200 line cards to the new SIP400 line cards. The software was developed using C language on Cisco’s IOS networking operating systems.-Implementation of microcode on Intel’s IXP 2800 network processor for Ethernet Loopback support. The loopback facility was provided in two modes – Facility & Terminal-Trained on Cisco’s ICND training and have knowledge of basic networking technologies.
