    Lab 1-1: Switch Startup and Initial Configuration.

    Task 1: Reload and check that the Switch is set to factory defaults.

    Step 1: Assign an IP address to your PC using the details listed in the visual topology diagram. The PC should be fitted with two network adapters check with the instructor if you are unsure which network adapter should be configured.

    Step 2: Access the Switch Console port using the method and information provided by the instructor.

    At the Switch> prompt (if you see any other prompt or are asked for a password contact the instructor), enter the erase startup-config command and make a note of the result.

    Why did this fail?

    Step 3: From the user prompt type in the command which enters privilege exec-mode.

    Does the system prompt change and if so, how?

    Now try and execute the Erase startup-config command, once again make a note of the output.

    Do you see a different console message?

    Step 4: Switches hold information about logical VLANs in a database stored in their flash memory and it is necessary to delete this database to reset the Switch back to factory defaults. PLEASE BE VERY CAREFUL WHEN USING THE DELETE COMMAND.

    From Privilege mode type in the following command and follow the system messages (if you are unsure what to do, contact the instructor before answering any of the system messages).

    Switch#Delete flash:vlan.dat

    Step 5: Use the appropriate command to verify that the Switch doesn’t have a current startup-configuration and use the appropriate show command to display information about the device hardware and software parameters.

    Step 6: Reload the Switch.

    Please note the Switch may take a few minutes to reload.

    Task 2: Defining a hostname and enabling a management IP address.

    Step 1: Change the hostname of the Switch to either SW1 or SW2

    Step 2: Assign your Switch a management IP address from the values identified in the visual topology diagram at the beginning of the lab exercise.

    Step 3: Verify connectivity between your PC and the Switch using the Ping command, remember that your PC might have a personal firewall installed which could prevent the Switch from Pinging the PC.

    Was the Ping successful ?

    If not, investigate and correct the problem.

    Task 3: Using context-sensitive help.

    Step 1: Access the privilege mode on your Switch and enter ? to list the available commands.

    Step 2: Using the ? navigate through the series of command options to set the system time to the current time and date. Note that the system will support abbreviated commands provided they are unique and using the Tab key will automatically complete the command.

    Step 3: Use a command to show the current time and date.

    Step 4: Type in the following command at the privilege command prompt.

    ! The next set of commands will configure the links to the core office

    The ! at the beginning of a line indicates that you are entering a comment into the running configuration, this can be very useful to other colleagues and engineers who are trying to ascertain the nature of the configuration.

    Step 5: To help navigate around the CLI (command line interface) a number of key combinations can be used. Spend a few minutes trying these combinations out and make a note of what they appear to do, for the best result execute a few valid show commands first.

    Ctrl P or the up arrow key

    Ctrl A

    Backspace

    Task 4: Changing default CLI parameters.

    Step 1: Using the show terminal command, verify that history is enabled and determine the current history size for the console Iine.

    Step 2: Use the appropriate command to change the history size to a value of 100 for the console line.

    Step 3: When you mistype a command, the system will try and translate it into an IP address which can take some time and be very annoying, however by issuing the no IP domain-lookup command it disables the translation look-up.

    At the command prompt enter a mistyped command and monitor how long it takes for the system to return an error message, now execute the no IP domain-lookup command and try the mistyped command for a second time and notice the difference.

    Step 4: When accessing the console port there is a default keyboard inactivity timeout of 10 minutes. Change this timer to 60 minutes.

    Step 5: What does the logging synchronous command do?

    Enable this command on the line console 0 port.

    Step 6: Save your running-configuration.

    Task 1: Reload and check that the Switch is set to factory defaults.

    Step 2: Access the Switch Console port using the method and information provided by the instructor.

    At the Switch> prompt (if you see any other prompt or are asked for a password contact the
    instructor), enter the erase startup-config command and make a note of the result.

    Switch>erase startup-config
    ^
    % Invalid input detected at '^' marker.

    Why did this fail?

    The erase startup-config command is not supported in user mode.

    Step 3: From the user prompt type in the command which enters privilege exec-mode.

    Switch>enable

    Switch#

    Does the system prompt change and if so, how?

    Displays hostname> in user mode

    Displays hostname# in privilege mode (sometimes called enable mode)

    Now try and execute the Erase startup-config command, once again make a note of the output.

    Do you see a different console message?

    YES

    Switch#erase startup-config

    Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]

    Step 5: Use the appropriate command to verify that the Switch doesn’t have a current startup-configuration and use the appropriate show command to display information about the device hardware and software parameters.

    Switch#sh startup

    startup-config is not present

    Switch#sh version

    Step 6: Reload the Switch.

    Switch#reload

    Proceed with reload? [confirm]

    Task 2: Defining a hostname and enabling a management IP address.

    Step 1: Change the hostname of the Switch to either SW1 or SW2

    Switch>enable

    Switch#conf t

    Switch(config)#hostname SW1

    Step 2: Assign your Switch a management IP address from the values identified in the visual topology diagram at the beginning of the lab exercise.

    SW1>enable

    SW1#conf t

    SW1(config)#interface vlan 1

    SW1(config-if)#ip address 10.1.1.11 255.255.255.0

    or

    SW2(config-if)#ip address 10.1.1.12 255.255.255.0

    Step 3: Verify connectivity between your PC and the Switch using the Ping command, remember that your PC might have a personal firewall installed which could prevent the Switch from Pinging the PC.

    Was the Ping successful ?

    YES

    If not, investigate and correct the problem.

    Task 3: Using context-sensitive help.

    Step 1: Access the privilege mode on your Switch and enter ? to list the available commands.

    PLEASE NOTE FOR ILLUSRATION PURPOSES THAT THE PROMPT FOR THE REST OF THE DOCUMENT WILL BE SHOWN AS SW or R, THIS WILL DIFFER FROM YOUR OUTPUT.

    SW#?
    Exec commands:
    <1-99>   Session number to resume
    clear   Reset functions
    clock   Manage the system clock
    configure   Enter configuration mode
    connect   Open a terminal connection
    copy   Copy from one file to another
    debug   Debugging functions (see also 'undebug')
    delete   Delete a file
    dir   List files on a filesystem
    disable   Turn off privileged commands
    disconnect   Disconnect an existing network connection
    enable   Turn on privileged commands
    erase   Erase a filesystem
    exit   Exit from the EXEC
    logout   Exit from the EXEC
    more   Display the contents of a file
    no   Disable debugging informations
    ping   Send echo messages
    reload   Halt and perform a cold restart
    resume   Resume an active network connection
    setup   Run the SETUP command facility
    --More--

    The above is an example output which may differ from the output you see.

    Step 2: Using the ? navigate through the series of command options to set the system time to the current time and date. Note that the system will support abbreviated commands provided they are unique and using the Tab key will automatically complete the command.

    SW#clock ?
     set Set the time and date
    SW#clock set ?
     hh:mm:ss Current Time
    SW#clock set 20:30:00 ?
     <1-31> Day of the month
     MONTH Month of the year
    SW#clock set 20:30:00 13 aug ?
     <1993-2035> Year
    SW#clock set 20:30:00 13 aug 2013

    Step 3: Use a command to show the current time and date.

    SW#show clock

    Step 5: To help navigate around the CLI (command line interface) a number of key combinations can be used. Spend a few minutes trying these combinations out and make a note of what they appear to do, for the best result execute a few valid show commands first.

    Ctrl P or the up arrow key Displays previous command entered
    Ctrl A                                 Moves the cursor to the front of the command line
    Backspace                         Deletes the previous last character

    Task 4: Changing default CLI parameters.

    Step 1: Using the show terminal command, verify that history is enabled and determine the current history size for the console Iine.

    History is enabled, history size is 10.

    Step 2: Use the appropriate command to change the history size to a value of 100 for the console line.

    SW#terminal history size 100

    Step 4: When accessing the console port there is a default keyboard inactivity timeout of 10 minutes. Change this timer to 60 minutes.

    SW#conf t

    SW(config)#line con 0

    SW(config-line)#exec-timeout 60

    Step 5: What does the logging synchronous command do?

    Prevents unsolicited messages merging with the commands you type in.

    Step 6: Save your running-configuration.

    SW#copy run start
