Overview

Description

Implementing Cisco Quality of Service (QOS) v2.5 provides learners with in-depth knowledge of QoS requirements, conceptual models such as best effort, IntServ, and DiffServ, and the implementation of QoS on Cisco platforms. The curriculum covers the theory of QoS, design issues, and configuration of various QoS mechanisms to facilitate the creation of effective administrative policies providing QoS.

Case studies and lab exercises included in the course help learners to apply the concepts from the individual modules to real-life scenarios. The course also gives learners design and usage rule for advanced QoS features. This gives the learners the opportunity to design and implement efficient, optimal, and trouble-free multiservice networks.

To participate in the hands-on labs in this class, you need to bring a laptop computer with the following:

  • Windows 7 or 8.1 or 10 is recommended. Mac OSX 10.6 or greater is supported as well.
  • Intel Celeron or better processors are preferred.
  • 1 GB or more of RAM
  • Browser Requirements: Internet Explorer 10 or greater or Mozilla Firefox. (Safari and Mozilla Firefox for Mac OSX)
  • All students are required to have administrator rights to their PCs and cannot be logged in to a domain using any Group Policies that will limit their machine’s capabilities.
  • If you do not have administrator rights to your PC, you at least need permissions to download, install, and run Cisco Any Connect Client.
  • If you are participating in a WebEx event, it is highly recommended to take this class at a location that has bandwidth speeds at a minimum of 1 Mbps bandwidth speeds.

Note: Students registering for this course will be receiving their course kit in a digital format. To be able to view your digital kit you will need to bring a laptop PC and/or a compatible iPad or Android tablet. The recommended system requirements and instructions to access the course kit content can be found at the following link: Digital Course Kit Requirements and Instructions
