Cisco Internetwork Troubleshooting (CIT)

CIT is a five-day instructor led course which provides delegates with hands-on experience in troubleshooting sub-optimal performance in a converged network. It is an integral part of any approach to obtaining the technical proficiency of a Cisco Certified Network Professional (CCNP). CIT deepens the delegates' technical ability rather than introducing new baseline technology.

Intended Audience
CIT provides advanced training for senior-level network support professionals. The target audience is expected to be:

Highly educated, with a background in engineering.
Well organized, logical and thoughtful.
Many among the target audience will be self-directed learners, researching topics to answer their own question.
intellectually curious, with an ability to evaluate information for relevance, completeness, and accuracy
Note: this could lead to situations where learners race ahead of the instructor's presentation in the classroom.

Skills

After completing this course, the student should be able to:

Given a fully operational internetwork, interconnecting end systems using Cisco systems routers and switches, administrative access to the network, and access to Cisco IOS commands and applications that are used to discover baseline configuration information, students will establish a baseline, so that the topology and configuration is diagrammed and tabulated.
Given interconnecting end systems using Cisco systems routers and switches, and the principles of a layered model troubleshooting approach, students will determine and document a 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, students will use Cisco IOS commands and applications to resolve optimization and failure problems at the physical or data link layer, so that the framed data moves from one end of a data link to another at the expected data error rate determined in the network baseline.
Given the sub-optimal operation of an internetwork at the network layer, a network baseline, and a list of user-reported and system-gathered symptoms, students will use Cisco IOS commands and application to resolve optimization and failure problems at the network layer, so that students can verify connectivity at Layer 3, the routing tables show reachability to all expected network devices specified in the baseline, and traffic is flowing over the correct path detailed in the baseline.
Given the sub-optimal operation of an internetwork at the transport or application layer, an application that is transmitting data at an unacceptable throughput from one destination to another, a list of user reported and system-gathered symptoms, and a network baseline, students will resolve an optimization or failure problem at the transport or application layer, so that the application transmits data at an expected throughput, latency, and jitter based on the network baseline.
