Jon Nock provides a reference letter for Shane Ellis who worked as a network configuration manager for 18 months. Shane proved proficient in layer 2 networking configurations including VLANs, trunks, and switches. He also configured services on core switches and Nexus switches, deployed new switches, and recently helped resolve issues with Nexus switches. Jon believes Shane would be an asset to any organization due to his skills, professionalism, and dedication.
