About this Course

Troubleshooting and Maintaining Cisco IP Networks (TSHOOT) v1.0 is an instructor-led training course that is presented by Cisco training partners to customers who use Cisco products. This five-day course is designed to help network professionals improve the skills and knowledge that they need to maintain their network and to diagnose and resolve network problems quickly and effectively. It also assists the network professional in preparing for Cisco CCNP certification. This course is a component of the CCNP curriculum.

The course is designed to teach professionals who work in complex network environments the skills that they need to maintain their networks and to diagnose and resolve network problems quickly and effectively. The course will provide information about troubleshooting and maintaining particular technologies, as well as procedural and organizational aspects of the troubleshooting and maintenance process. A large part of the training will consist of practicing these skills and reinforcing the concepts by putting them to use in a controlled environment. At the end of the course, the students will have increased their skill level and developed a set of best practices that are based on their own experience and the experiences of other students and that they can take back to their organizations.
