NET 228 - Cisco Networking II

Credits: 4
Lecture Hours: 2
Lab Hours: 4
Practicum Hours: 0
Work Experience: 0
Course Type: Voc/Tech
This course describes the architecture, components, and operations of routers and switches in a small network. Students learn how to configure a router and a switch for basic functionality. By the end of this course, students will be able to configure and troubleshoot routers and switches and resolve common issues with static routing, virtual LANS, and inter-VLAN routing in both IPv4 and IPv6 networks.
Prerequisite: NET 213
