All rights reserved.INTRO v Module Summary The Cisco Discovery Protocol is an information-gathering tool used by network administrators to get information about directly connected Cisco devices, including the following for each device: device identifier, address list, port identifier, capabilities list, and platform. You can view this information by using the show cdp command. The Telnet application is a method for obtaining information about remote devices that are not accessible by CDP; a Telnet session can be ended on a Cisco device using the exit, logout, disconnect, or clear command. When a router boots up, it performs a series of steps, including performing tests, finding and loading the Cisco IOS software, finding and loading configurations, and running the Cisco IOS software. The Cisco IFS feature provides a single interface to all the file systems that a router uses. As any network grows, storage of Cisco IOS images and configuration files on a central TFTP server enables control of the number and revision level of Cisco IOS images and configuration files that must be maintained.
