Router Boot Sequence and Verification |
Overview
This page summarizes the topics discussed in this module.
A Cisco router cannot operate without the Cisco IOS. Each Cisco router has a predetermined boot-up sequence that is used to locate and load the Cisco IOS. This module will describe the stages and importance of this bootup procedure.
Cisco internetworking devices use several different files to operate, such as Cisco IOS images and configuration files. A network administrator must manage these files to ensure that the proper versions are used and that necessary backups are performed. This module also describes the Cisco file system and provides the tools to manage it effectively.
This module covers some of the objectives for the CCNA 640-801, INTRO 640-821, and ICND 640-811 exams. -
