Implementing Cisco Quality of Service v2.5


Course Description


Overview

QOS v2.5 includes several updates and aligns to a minimally updated blueprint. In comparison to the previous version, all graphics have been updated and content flow has been changed to reduce the amount of slides covered during course delivery. Several topics have been removed, while some topics, such as Cisco AutoQoS, QoS monitoring, and Campus QoS have been added or expanded. Course content has been adapted to Cisco IOS Software Release 15 and technically updated. Labs were expanded and reflect an updated topology and current networking gear.  

Audience

The primary target audiences for the course are:
  • Pre- and post-sales technical engineers responsible for designing, implementing, or troubleshooting networks
  • Network architects responsible for designing multiservice networks to carry voice, video, and data traffic in enterprise or service provider environments
  • Advanced Unified Communications Specialization
  • Master UC Specialization
  • Master Telepresence ATP
Secondary target audiences are:
  • CCIE R&S Candidates
