This module provides the student with the knowledge and skills necessary to to plan, configure, secure and verify the implementation of complex enterprise switching solutions using Cisco's Campus Enterprise Architecture. 

Learning Outcomes

On completion of this module the learner will/should be able to;


Evaluate a campus network in order to design a reliable, scalable network


Configure, verify and troubleshoot switches using VTP, STP, Link aggregation


Assess a switched network in order to determine and implement appropriate security features.

Module Assessment Strategies

Continuous assessment will take place in a laboratory environment employing simulation techniques as well as hands on testing using approved industry standard equipment
