At the CLI prompt, press ?. Some of the following commands should be displayed:userhost ?Possible completions:clear Clear information in the systemconfigure Manipulate configuration informationping Ping a remote target List a few of the remaining commands: Step 2Type the following at the CLI prompt:CLI 入门实验 4userhost c?Possible completions:clear Clear information in the systemconfigure Manipulate configuration informationuserhost cWhat command could be used from the operational model to display all show commands that start with c?Step 3Type the following command at the CLI prompt:userhost clear ?Possible completions:arp Clear address-resolution tablesbgp Clear BGP informationisis Clear IS-IS information.Part 2Word CompletionStep 1Use command completion:userhost show ii is ambiguousPossible completions:interfaces Show interface informationWhat other command that starts with “i” is provided when you type the above command?Step 2Type the following at the CLI prompt:userhost show interfacesPhysical device fxp0Type: ethernet, Encapsulation: ethernet, MTU: 1514Flags: present running no-carrier hardware-downCurrent mac 00:a0:c9:36:b3:a7, Hardware mac 00:a0:c9:36:b3:a7.userhostPart 3CLI MessagesStep 1Type the following command: CLI 入门实验 5userhost clear routeWhat message does the router display when you type this command? Why?Step 2Type the following command:userhost configureThis command puts the CLI in the configuration mode. What does the router display when entering this mode?Step 3Type the following command while in CLI configuration mode:userhost# quitWhat message does the router display when you exit from configuration mode?Part 4Keyboard SequencesStep 1From the CLI prompt, type the following commands:userhost show interfacesPress .What happens to the cursor when you enter this keyboard sequence?Press .What happens to the cursor when you enter this keyboard sequence? Press .What happens to the cursor when you press this keyboard sequence?Press .What happens to the cursor when you press this keyboard sequence? Step 2Type the following commands:CLI 入门实验 6userhost show interfacesuserhost show routeuserhost show system usersThese three commands are now stored in the CLI history buffer.Press twice. What happens?Press twice. What happens?Part 5Command OutputCommand output might exceed one full screen. For example, the show interface detail command displays information about the routers interfaces. Type it now:userhost show interfaces detailWhat does the router display?What happens when you press the space bar? What happens when you press the Enter key?
