Description

Troubleshooting and Maintaining Cisco IP Networks (TSHOOT) v2.0 is a 5 day instructor led training course developed to help students prepare for the Cisco CCNP certification. The TSHOOT course is a component of the CCNP Routing and Switching curriculum.
This course is designed to train network engineers on monitoring and troubleshooting routed and switched networks through extensive use of hands-on lab exercises. The goal is to help network professionals gain the skills and knowledge needed to diagnose and resolve network problems quickly and effectively. Some older topics have been removed or simplified from TSHOOT v1.0, while several new IPv6 routing topics have been added. The course content has been adapted to Cisco IOS Software Release 15 and technically updated.

After completing this course, students will be able to:

  • Describe the troubleshooting tools and methodologies that are used to identify and resolve issues in complex enterprise networks
