Description
This course will give you an extended understanding for how switched networks are implemented and what techniques you should use to increase performance, security and redundancy in switched networks. The course is given in workshop format and contains many hands-on exercises. A Cisco lab with Layer 2 and Layer 3 switches are used.
Target group
This course is designed for network engineers with responsibility for design, configuration and integration of switched networks.
Prerequisites
