Cisco Internetwork Troubleshooting (CIT)

Description

Thanks to the consistent introduction of new technologies and the Architecture for Voice, Video, and Integrated Data (AVVID), Cisco internetworks have become more complex than ever before. Moreover, just as the complexity of networks has increased, so has the need for sophisticated and efficient troubleshooting approaches and strategies. The Cisco Internetwork Troubleshooting (CIT) 5.2 course provides students with best practice, advanced troubleshooting techniques straight from Cisco Certified Internetwork Experts (CCIE) and Technical Assistance Center (TAC) personnel. In order to ensure students fully master the troubleshooting approaches contained in the curriculum, the course instructors present numerous examples and extremely complex hands-on troubleshooting labs. The challenging and exciting hands-on labs that students perform consist of real-world, CCIE-level troubleshooting problems on a variety of actual Cisco routers and switches. This course is a perfect conclusion to a students CCNP curriculum and a critical component for anyone tasked with supporting Cisco equipment in any way.

Objectives

Upon completion of the Cisco Internetwork Troubleshooting (CIT) course, the student will be able to:

• Use Cisco IOS commands to discover baseline configuration information Fully diagram and document an existing Cisco network topology
• Use the principles of a general, layered-model troubleshooting approach to determine and document a specific troubleshooting strategy so that internetwork problems can be detected and corrected consistently
• Given the sub-optimal operation of an internetwork at the physical or data link layer, a list of user-reported symptoms, and a network baseline - use Cisco IOS commands to resolve optimization and failure problems at the physical or data link layer
• Given the sub-optimal operation of an internetwork, a list of user-reported symptoms, and a network baseline - use Cisco IOS commands to resolve optimization and failure problems at the network layer and above

Audience

Cisco Internetwork Troubleshooting (CIT) provides advanced training for senior-level network support professionals. This course is appropriate for any technical engineer or technical sales representative that is interested in sophisticated troubleshooting techniques for complex Cisco networks.
