Description

Smooth operation and high availability of the network are crucial to organizations. Unplanned downtime can quickly lead to loss of productivity and, therefore, financial loss. To maximize the availability of the network, it is important to plan network maintenance processes and procedures carefully. Troubleshooting is a part of network maintenance that every network engineer needs to be capable of performing. In complex environments, troubleshooting can be a daunting task, and the only way to diagnose and resolve problems quickly and effectively is by following a structured approach. This approach involves having well-defined and documented troubleshooting procedures and aligning troubleshooting procedures to general network maintenance procedures. Additionally, troubleshooting can be a very time-consuming process. Using the tools built into the Cisco IOS Software can help shorten the time to diagnose and resolve problems quickly. There are many technologies and protocols that can be leveraged in combination with specialized tools and applications to support troubleshooting and maintenance processes. This course describes troubleshooting methodologies as well as troubleshooting procedures and processes. Basic Cisco IOS tools and logging procedures are also covered.
