Managing Network Performance

Overview/Description
To outline why it may be necessary to implement queuing technologies on a WAN connection, and to identify and use the commands so as to prioritize traffic over a WAN connection and optimize WAN traffic over a WAN link by compressing data

Target Audience
Network engineers responsible for configuring, implementing, troubleshooting, and managing WAN and remote access solutions; network architects responsible for designing WAN and remote access solutions; CCNP candidates; CCIE candidates

Prerequisites
A knowledge of general networking terms and concepts; experience in general Cisco router operation and configuration, including TCP/IP, routing protocols (RIP, IGRP), routed protocols (IP, IPX), standard and extended access lists, PPP operation and configuration over serial links, Frame Relay operation and configuration on interfaces and subinterfaces, and legacy DDR over ISDN-BRI operation and configuration; a basic knowledge of data networking equivalent to the information in the Cisco Certified Network Associate Basics (CCNAB) v2.0 course and the Interconnecting Cisco Network Devices (ICND) v2.0 course; experience working in a network environment is recommended

Expected Duration
160 Minutes

Objectives:

Managing Network Performance

  • recall when to implement traffic prioritization techniques, list the steps required to establish a queuing policy, and correctly choose a Cisco IOS queuing option.
  • configure weighted fair queuing on an internetwork in order to keep interactive traffic operational during times of congestion.
  • identify the benefits and features of class-based fair weight queuing (CBFWQ) and outline the steps and commands required to configure CBFWQ.
  • configure weighted fair queuing and class-based weighted fair queuing in a given scenario.
  • identify the features of low latency queuing (LLQ) and configure LLQ with the use of the priority command.
  • verify queuing operation using the show queuing command and differentiate between flow-based WFQ, class-based WFQ, and other queuing methods.
  • differentiate between the types of data compression supported by Cisco equipment, and recall the considerations for selecting a compression algorithm to optimize a WAN utilization, and configure compression on a WAN interface.
  • configure low latency queuing and data compression in a given scenario.
