Part $3$: Set 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.

S$1$# show clock

Question:

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.

S$1$# clock

Question

What information is displayed?

c$.$ The $\%$ Incomplete command$$ message is returned by the IOS. This indicates that the clock command needs more parameters. Any time more information is needed, help can be provided by typing a space after the command and the question mark $(?).$

S$1$# clock $?$

Question:

What information is displayed?

d$.$ Set the clock using the clock set command. Proceed through the command one step at a time.

S$1$# clock set $?$

Questions:

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 more parameters are needed.

S$1$# clock set $15$:$00$:$00?$

The output returns a 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 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:

S$1$# show clock

$*15$:$0$:$4\mathrm{.}869$ UTC Tue Jan $312035$

g$.$ If you were not successful, try the following command to obtain the output above:

S$1$# clock set $15$:$00$:$0031$ Jan $2035$

Step $2$: Explore additional command messages.

a$.$ The IOS provides various outputs for incorrect or incomplete commands. 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 commands and record the messages:

S$1$# cl
