Bridging Learning Gaps in Cisco CLI: The Smart Cli Tool (SCLIT) Approach

Abstract

Objective: Networking students frequently face difficulties in mastering Cisco command-line interface (CLI) commands using Cisco Packet Tracer, particularly when it comes to recognizing mistakes, correcting syntax errors, and conducting effective troubleshooting. These challenges often hinder the learning process, reduce student confidence, and increase reliance on instructors. To address this issue, the Smart Command-Line Interface Tool (sCLIt) was developed as a supplementary educational aid to enhance traditional Packet Tracer activities. The objectives of this study are clear. The first one is to assist students in identifying and applying correct Cisco CLI commands. Second is to provide real-time feedback and corrective suggestions for syntax errors, and the third one is to foster greater student independence and confidence in troubleshooting tasks.

Research Method: The tool was developed using a prototype-driven approach that involved iterative design, testing, feedback collection, and refinement. A quantitative descriptive design was employed to evaluate sCLIt, with data collected through structured Likert-scale questionnaire and supported by student’s final exam results. A total of 30 diploma-level students at Politeknik METrO Tasek Gelugor participated in the survey, while final exam results were analyzed across two different class in the same cohort which one class use the sCLIt and another one did not.

Findings: Findings from the survey indicated strong student agreement with the usefulness of the tool, with average mean scores ranging from 4.00 to 4.26 (out of 5). The tool was rated highest for providing real-time feedback on syntax error and suggestions for correction. Students also reported improvements in troubleshooting ability and confidence, though some indicated that instructor guidance remained valuable. Analysis of final exam results showed and overall average of 51.4, with one class achieving higher scores but with greater variability, suggesting that sCLIt benefits most learners but that weaker students may still require additional scaffolding.

Originality: The Smart CLI Tool (sCLIt) demonstrates significant potential as a virtual tutor that enhances networking education by offering real-time validation, guidance, and error detection. Its contribution lies in reducing common student errors, building self-directed learning, and complementing traditional instructor support. With further development such as the inclusion of tutorials, command libraries, and adaptive learning features, sCLIt could play a greater role in modernizing networking pedagogy and supporting diverse learners in both classroom and remote learning contexts
