  1 - 7 CCNA 3: Switching Basics and Intermediate Routing v 3.0 - Lab 6.2.7a Copyright  2003, Cisco Systems, Inc.   Lab 6.2.7a Managing Switch Operating System Files Objective ã Create and verify a basic switch configuration. ã Backup the switch IOS to a TFTP server and then restore it. Background/Preparation Cable a network similar to the one in the diagram. The configuration output used in this lab isproduced from a 2950 series switch. Any other switch used may produce different output. Thefollowing steps are to be executed on each switch unless specifically instructed otherwise.Instructions are also provided for the 1900 Series switch, which initially displays a User InterfaceMenu. Select the “Command Line” option from the menu to perform the steps for this lab.Start a HyperTerminal session. Note: Go to the erase and reload instructions at the end of this lab. Perform those steps on allswitches in this lab assignment before continuing. Step 1 Configure the switch Configure the hostname, access and command mode passwords, as well as the management LANsettings. These values are shown in the chart. If problems occur while performing this configuration,refer to the Basic Switch Configuration lab. Step 2 Configure the hosts attached to the switch Configure the host to use the same subnet for the address, mask, and default gateway as on theswitch. This host will act as the TFTP server in this lab. Be sure to take note of the IP addressassigned.  2 - 7 CCNA 3: Switching Basics and Intermediate Routing v 3.0 - Lab 6.2.7a Copyright  2003, Cisco Systems, Inc.   Step 3 Verify connectivity a. To verify that the host and switch are correctly configured, ping the switch IP address from thehost.b. Was the ping successful?  ____________________________________________________   c. If the answer is no, troubleshoot the host and switch configurations. Step 4 Starting and configuring the Cisco TFTP server  a. The TFTP server that that is shown, may not be like the one that is used in this classroom.Please check with the instructor for the operating instructions for the TFTP server used in placeof the Cisco TFTP server.b. Once the TFTP server is running and shows the proper address configured on the workstation,proceed to the actual copying of the IOS file to the switch.   Step 5 Copying IOS to the TFTP server (1900: Skip to Step 8) a. Before trying to copy the files, verify that the TFTP server is runningb. What is the IP address of the TFTP server?  ______________________________________   c. From the console session, enter  show flash .d. What is the name and length of the Cisco IOS image stored in flash?  __________________________________________________________________________   e. What attributes can be identified from the codes in the Cisco IOS filename?  __________________________________________________________________________   f. From the console session in the privileged EXEC mode, enter the copy flash tftp   command. At the prompt enter the IP address of the TFTP server.  ALSwitch# copy flash tftp  Source filename []? c2950-c3h2s-mz.120-5.3.WC.1.bin Address or name of remote host []? filename [c2950-c3h2s-mz.120-5.3.WC.1.bin]?[Enter]!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!  3 - 7 CCNA 3: Switching Basics and Intermediate Routing v 3.0 - Lab 6.2.7a Copyright  2003, Cisco Systems, Inc.   !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1674921 bytes copied in 29.952 secs (57755 bytes/sec) ALSwitch# 2900:  ALSwitch# copy flash:c2900XL-hs-mz-112.8.10-SA6.bin tftp  Source filename [c2900XL-hs-mz-112.8.10-SA6.bin]?[Enter]Destination IP address or hostname []? filename [c2900XL-hs-mz-112.8.10-SA6.bin]?[Enter]!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1119104 bytes copied in 22.895 secs (50868 bytes/sec) ALSwitch# 1900: (This does not seem possible on the 1900 series – download only) Step 6 Verify the transfer to the TFTP server  a. Verify the transfer by checking the TFTP server log file by clicking View > Log File . The outputshould look similar to the following output: Mon Sep 16 14:10:08 2002: Receiving ‘c2950-c3h2s-mz.120-5.3.WC.1.bin’in binary modeMon Sep 16 14:11:14 2002: Successful. b. Verify the flash image size in the TFTP server directory. To locate it click on View > Options .This will show the TFTP server root directory. It should be similar to the following, unless thedefault directories were changed. C:\Program Files\Cisco Systems\Cisco TFTP Server c. Locate this directory using the File Manager and look at the detail listing of the file. The filelength in the show flash command should be the same file size as the file stored on the TFTPserver. If the file sizes are not identical in size, check with the instructor. Step 7 Copying IOS from the TFTP server  a. Now that the IOS is backed up, the image must be tested and the IOS must be restored to theswitch. Verify again that the TFTP server is running, sharing a network with the switch and canbe reached by pinging the TFTP server IP address.b. Record the IP address of the TFTP server.  _______________________________________   c. Now start the actual copying, from the privileged EXEC prompt as follows: Note: It is important that is process is not interrupted.    ALSwitch# copy tftp flash   Address or name of remote host []? filename []? c2950-c3h2s-mz.120-5.3.WC.1.binDestination filename [c2950-c3h2s-mz.120-5.3.WC.1.bin]?

The switch may prompt for an overwrite flash. Will the image fit in available flash?  __________   e. What is the size of the file being loaded?  _________________________________________   f. What happened on the switch console screen as the file was being downloaded?  __________________________________________________________________________   g. Was the verification successful?  _______________________________________________   h. Was the whole operation successful?  ___________________________________________  i. Select option “F” to go to the Firmware Configuration menu from the Main Menu. An example of the Firmware Configuration Menu is: Catalyst 1900 - Firmware Configuration---------------------- System Information -----------------------------FLASH: 1024K bytesV8.01.00 : Enterprise EditionUpgrade status:No upgrade currently in progress.---------------------- Settings ---------------------------------------[S] TFTP Server name or IP address[F] Filename for firmware upgrades cat1900.bin[A] Accept upgrade transfer from other hosts Enabled---------------------- Actions ----------------------------------------[U] System XMODEM upgrade [D] Download test subsystem(XMODEM)[T] System TFTP upgrade [X] Exit to Main MenuEnter Selection: Step 8 Upgrading with a TFTP Server  a. Copy the switch firmware file to the TFTP server.b. Select option “S” from the Firmware Configuration menu and enter the IP address of the server where the switch upgrade file is located.c. Select option “F” from the Firmware Configuration menu and enter the name of the firmware-upgrade file.d. Select '”T” from the Firmware Configuration menu to initiate the upgrade.e. Verify the upgrade is in progress by checking the Upgrade status section of the FirmwareConfiguration Menu. If the upgrade is in progress, the field reads in-progress .
