ICND1 v2.0 – Interconnecting Cisco Networking Devices

Interconnecting Cisco Networking Devices, Part 1 (ICND1) v2.0 is a instructor-led training course that teaches learners how to install, operate, configure, and verify a basic IPv4 and IPv6 network, including configuring a LAN switch, configuring an IP router, connecting to a WAN, and identifying basic security threats.

The course maybe followed by the Interconnecting Cisco Networking Devices, Part2 (ICND2) v2.0 course, which covers topics in more depth and teaches learners how to perform basic troubleshooting steps in enterprise branch office networks, preparing learners for Cisco CCNA certification.


Upon completing this course, the learner will be able to meet these overall objectives:

  • Describe network fundamentals and build simple LANs
  • Establish Internet connectivity
  • Manage network device security
  • Expand small- to medium-sized networks with WAN connectivity
  • Describe IPv6 basics


The knowledge and skills that a learner must have before attending this course are as follows:

  • Basic computer literacy
  • Basic PC operating system navigation skills
  • Basic Internet usage skills
  • Basic IP address knowledge


  • Target Candidate: Individuals seeking the Cisco CCENT certification, or Cisco CCNA Routing and Switching certification. The course is also appropriate for pre-sales and post-sales network engineers involved in the installation and support of enterprise branch office networks.
  • Key Job Tasks:
    • Configure: Implement the identified solution by applying the planned implementation processes using Cisco IOS commands and applications in the correct order to the selected devices and portions of the network.
    • Verify: Use the appropriate show and debug commands and applications to ensure that the solution was correctly implemented and is performing as desired.
  • Job roles: Entry Level Network Engineer, Network Administrator, Network Support Technician, and/or Help Desk Technician.
