Background
In this activity, you will practice
skills necessary for navigating the Cisco IOS, including different user access
modes, various configuration modes, and common commands you use on a regular
basis. You also practice accessing the context-sensitive Help by configuring
the clock command.
Part 1: Basic Connections, Accessing the CLI and Exploring Help
In Part 1 of this activity, you connect a
PC to a switch using a console connection and explore various command modes and
Help features.
Step 1: Connect PC1 to S1 uses a console cable.
a.
Click the Connections icon (the one that looks like a lightning bolt) in the
lower left corner of the Packet Tracer window.
b.
Select the light blue Console
cable by clicking it. The mouse pointer will change to what appears to be a
connector with a cable dangling off of it.
c.
Click PC1; a window displays an option for an RS-232 connection.
d.
Drag the other end of the
console connection to the S1 switch and click the switch to bring up the
connection list.
e.
Select the Console port to
complete the connection.
Step 2: Establish a terminal session with S1.
a.
Click PC1 and then select the Desktop
tab.
b.
Click the Terminal application icon; verify that the Port Configuration
default settings are correct.
What is the setting for bits per second? _______
c.
Click OK.
d.
The screen that appears may
have several messages displayed. Somewhere on the display there should be a Press RETURN to get started! message. Press ENTER.
What is the prompt displayed on the
screen? _________
Step 3: Explore the IOS Help.
a.
The IOS can provide help for
commands depending on the level being accessed. The prompt currently being
displayed is called User EXEC and
the device is waiting for a command. The most basic form of help is to type a
question mark (?) at the prompt to display a list of commands.
S1> ?
Which command begins with the letter ‘C’?
___________________
b.
At the prompt, type t, followed by a question mark (?).
S1> t?
Which commands are displayed? ___________________________
c.
At the prompt, type te, followed by a question mark (?).
S1> te?
Which commands are displayed? ___________________
This type of help is known as context-sensitive Help, providing more
information as the commands are expanded.
Part 2: Exploring EXEC Modes
In Part 2 of this activity, you switch to
privileged EXEC mode and issue additional commands.
Step 1: Enter privileged EXEC mode.
a.
At the prompt, type the
question mark (?).
S1> ?
What information is displayed that
describes the enable command? _____________________________
b.
Type en and press the Tab
key.
S1> en
What displays after pressing the Tab key? _________
This is called command completion or tab
completion. When part of a command is typed, the Tab key can be used to complete the partial command. If the
characters typed are enough to make the command unique, as in the case with the
enable command, the remaining
portion is displayed.
What would happen if you were to type te at the prompt?
____________________________________________________________________________________
____________________________________________________________________________________
____________________________________________________________________________________
c.
Enter the enable command and press ENTER.
How does the prompt change?
____________________________________________________________________________________
d.
When prompted, type the question
mark (?).
S1# ?
Previously there was one command that
started with the letter ‘C’ in user EXEC mode. How many commands are displayed
now that privileged EXEC mode is active? (Hint:
you could type c? to list just the commands beginning with ‘C’.)
____________________________________________________________________________________
Step 2: Enter Global Configuration mode.
a.
One of the commands starting
with the letter ‘C’ is configure
when in Privileged EXEC mode. Type either the full command or enough of the
command to make it unique along with the <Tab> key to issue the command and press
S1# configure
What is the message that is displayed?
____________________________________________________________________________________
b.
Press the
How does the prompt change? ___________________________________________________________
c.
This is called global
configuration mode. This mode will be explored further in upcoming activities
and labs. For now exit back to Privileged EXEC mode by typing end, exit or Ctrl-Z.
S1(config)# exit
S1#
Part 3: Setting the Clock
Step 1: Use the clock command.
a.
Use the clock command to further explore Help and command syntax. Type show clock at the privileged EXEC prompt.
S1# show
clock
What information is displayed? What is the year that is displayed?
____________________________________________________________________________________
b.
Use the context-sensitive Help and
the clock command to set the time on
the switch to the current time. Enter the command clock and press ENTER.
S1# clock
What information is displayed? ___________________________________________________________
c.
The % Incomplete command message
is returned by the IOS indicating that the clock
command needs further parameters. Any time more information is needed help can
be provided by typing a space after the command and the question mark (?).
S1# clock
?
What information is displayed? ___________________________________________________________
d.
Set the clock using the clock set command. Continue proceeding
through the command one step at a time.
S1# clock
set ?
What information is being requested?
_____________________________________________________
What would have been displayed if only
the clock set command had been
entered and no request for help was made by using the question mark? ________________________________________________
e.
Based on the information
requested by issuing the clock set ?
command, enter a time of 3:00 p.m. by using the 24-hour format of
15:00:00. Check to see if further parameters are needed.
S1# clock
set 15:00:00 ?
The output returns the request for more
information:
<1-31> Day of the month
MONTH
Month of the year
f.
Attempt to set the date to
01/31/2035 using the format requested. It may be necessary to request
additional help using the context-sensitive Help to complete the process. When
finished, issue the show clock command
to display the clock setting. The
resulting command output should display as:
S1# show
clock
*15:0:4.869 UTC Tue Jan 31 2035
g.
If you were not successful, try
the following command to obtain the output above:
S1# clock
set 15:00:00 31 Jan 2035
Step 2: Explore additional command messages.
a.
The IOS provides various
outputs for incorrect or incomplete commands as experienced in earlier
sections. Continue to use the clock
command to explore additional messages that may be encountered as you learn to
use the IOS.
b.
Issue the following command and
record the messages:
S1# cl
