Course description

The goal of CIT is to provide learners with hands-on experience in troubleshooting sub-optimal performance in a converged network and is an integral part of any approach to obtain the technical proficiency of Cisco Certified Network Professional (CCNP). CIT deepens the learner's technical ability rather than introducing new baseline technology.

Network discovery and documentation
End-system discovery and documentation
Analyzing traffic flow using IOS tools
Creating a network baseline
Problem solving methodology
Cisco IOS diagnostic commands
Troubleshooting the physical and data-link layers, including Ethernet, Frame Relay, and T1 problems
Troubleshooting Catalyst switch problems
Troubleshooting network layer problems, including EIGRP, OSPF, and BGP
Troubleshooting application layer problems

Course duration

5 days

Prerequisites

ICND
BSCI
BCMSN
BCRAN

Target Audience

CIT provides advanced training for senior-level network support professionals. The target audience is expected to be highly educated, with a background in gbineering. They tend to be well organized, logical, and thoughtful. Many among the target audience will be self-directed learners, researching topics to answer their own question. Their intellectual curiosity, coupled with their ability to evaluate information for relevance, completeness, and accuracy, could lead to situations where learners race ahead of the instructor's presentation in the classroom.
