Cisco Networking Lab CCNA Lab Guide (Release 2)1 A Loopback interface is a logical interface that is often used for purposes such as testing. you can create as many Loopback interfaces as you want on a router. the Loopback interface is on by default.2 Access to the server from the terminal to control each router and switch is achieved through reverse Telnet, where the Telnet port number is the line number plus 2000, for example, line3, whose port number is 2003. To simplify the operation, use the iphost command to define a series of host names so that you can directly enter the host name to control the devices connected on the line.3 Define the alias of the command to facilitate the operation, for example, crl=clear line3, the clear line command is to clear the line, sometimes due to the line occupation and other situations can not be connected to the controlled device, you need to clear the line. 4 Authorization through the privilege exec command allows lower-level users to execute commands of higher-level users.
