NETW905 – Introduction Lab Network Fundamentals – Chapter 6 [6.4 & 6.5] Network Fundamentals – Chapter 11 Version 4.0 © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 1 Objectives Determine the network portion of the host address and explain the role of the subnet mask in dividing networks (Basic Subnetting). Define the role of the Internetwork Operating System (IOS). Use Cisco CLI commands to perform basic router and switch configuration and verification. Given a network addressing scheme, select, apply, and verify appropriate addressing parameters to a host. Use common utilities to verify network connectivity between hosts. Use common utilities to establish a relative performance baseline for the network. © 2007 Cisco Systems, Inc. All rights reserved.
