This title explains the concepts, commands and graphics necessary for configuring Cisco devices in corporate networks and achieving the much-valued certification. The book contains forty-four chapters divided into four clearly defined sections, covering topics such as routing, switching, VoIP, MPLS, security, wireless, QoS, etc., in an order that facilitates reading and learning.

The authors have employed all their experience as trainers and certified technicians, producing a compendium free from unnecessary material and covering only the most relevant themes. They have taken zealous care to retain the terminology of the field, respecting the slang used in communications so that the use of the Spanish language does not represent an obstacle as it has done until now.
