1) Đây là quy trình backup cấu hình của Switch vào một FTP server (anh có thể cài phần mềm FTP server vào 1 máy tính và nối nó vào cổng fast ethernet của Switch, đồng thời anh cần phải đặt IP cho card mạng LAN của PC.
Backup Configuration and Software Image
Perform a backup of the switch configuration to the PC that runs the TFTP server. If you lose the switch configuration for any reason, you can always restore the configuration from the TFTP server.
Issue the copy startup-config tftp command on the 3550 in order to back up your current configuration to a TFTP server. Here is a sample command output:
3550# copy startup-config tftp
Address or name of remote host []? 20.20.20.2
!--- Enter your TFTP server IP.
!--- Press Return or Enter.
Destination filename [3550-confg]?
!--- Press Return or Enter.
!--- The file 3550-confg saves in the
!--- TFTP server root directory.

Software Upgrade Procedure for 3550 Series Switches
There are two upgrade procedures available for the 3550:
If you want to use the CLI only and do not intend to use the CMS software, complete the Step-by-Step Procedure for the 3550 with Use of Only the Cisco IOS Image (.bin File) (http://www.cisco.com/en/US/products/hw/switches/ps646/products_configuration_example09186a0080169623.sht ml#concept9).
If you want to use the latest version of CMS software, complete the Step-by-Step Procedure for the 3550 with Use of the CMS Image (.tar File) (http://www.cisco.com/en/US/products/hw/switches/ps646/products_configuration_example09186a0080169623.sht ml#concept10). Note: For more information on the CMS, refer to the Multimedia Presentation (http://www.cisco.com/warp/public/779/smbiz/multimedia/).
Step-by-Step Procedure for the 3550 with Use of Only the Cisco IOS Image (.bin File)
In this example, you upgrade the software on a 3550 from Cisco IOS Software Release 12.1(12c)EA1 to Cisco IOS Software Release 12.1(13)EA1 with use of only the Cisco IOS image (.bin file). The procedure is the same despite the version of software that you use.
Issue the show version command in order to view the current version of software that you run.
Here is a sample command output:
3550# show version
Cisco Internetwork Operating System Software
IOS (tm) C3550 Software (C3550-I5Q3L2-M), Version 12.1(12c)EA1, RELEASE SOFTWARE
(fc1)
!--- The current software version is Cisco IOS Software Release 12.1(12c)EA1.
From the LAN Switches section of Downloads - Switches (http://tools.cisco.com/support/downloads/go/MDFTree.x?butype=switches) http://www.cisco.com/apps-ui/generic/interim/images/popup_icon.gif ( registered (http://tools.cisco.com/RPF/register/register.do) customers only) , choose Catalyst 3550 software and find the image that you want to download.
Note the size of the image in bytes. This example uses the file c3550-i5q3l2-mz.121-13.EA1.bin. The "i5q3l2" at the start of the file name tells you that this image is an EMI. The image size is 3993612 bytes, or approximately 4 MB.
Note: The procedure is the same for the SMI. The SMI image has "i9q3l2" at the start of the file name. The SMI image is smaller and takes up less room in Flash. If you still have questions about whether to use an SMI or EMI image, see the Understand 3550 Software Image Naming Conventions: SMI and EMI (http://www.cisco.com/en/US/products/hw/switches/ps646/products_configuration_example09186a0080169623.sht ml#concept2) section of this document.
Download the image that you want.
Issue the dir flash: command on the 3550 in order to verify the amount of free memory that you have for the upgrade.
Here is a sample command output:
3550# dir flash:
Directory of flash:/

!--- Notice the "d" for directory in the permissions statement.
15998976 bytes total (1949184 bytes free)
!--- There are just under 2 MB of memory left, which is not enough.
!--- A deletion of one of the old images or, possibly, a directory
!--- is necessary to upgrade.
3550# Note: If you already have enough room in Flash for the upgrade, proceed directly to Step 6.
Issue the delete command in order to remove the old Cisco IOS Software Release 12.1(9)EA1c image (.bin file).
This deletion frees up enough room for the upgrade. Here is a sample command output:
3550# delete flash:c3550-i5q3l2-mz.121-9.EA1c.bin
Delete filename [c3550-i5q3l2-mz.121-9.EA1c.bin]?
!--- Press Return or Enter.
Delete flash:c3550-i5q3l2-mz.121-9.EA1c.bin? [confirm]
!--- Press Return or Enter.

15998976 bytes total (5334016 bytes free)
!--- After you delete the old Cisco IOS image file, there is now
!--- over 5 MB of free memory. There is enough room for the upgrade.
3550# An upgrade can require you to free up even more space. The requirement depends on how many images you have stored in Flash. You can delete an old image directory to free up this space.
Note: Remember this storage location so that you can find the old Cisco IOS image (.bin file) as well as the files that you need for the CMS. If you do not use the web interface to manage the switch or you have a newer image directory, the storage location is not a problem.
Issue the delete /force /recursive command in order to delete an image directory and all the subdirectories and files in the image directory. Here is a sample command output:
3550# delete /force /recursive flash:c3550-i5q3l2-mz.121-11.EA1a
Delete filename [c3550-i5q3l2-mz.121-11.EA1a]?

Note the size of the image in bytes. This example uses the file c3550-i5q3l2-tar.121-13.EA1.tar. The "i5q3l2" at the start of the file name tells you that this image is an EMI. The image size is 6011904 bytes, or approximately 6 MB.
Note: The procedure is the same for the SMI. The SMI image has "i9q3l2" at the start of the file name. The SMI image is smaller and takes up less room in Flash. If you still have questions about whether to use an SMI or EMI image, see the Understand 3550 Software Image Naming Conventions: SMI and EMI (http://www.cisco.com/en/US/products/hw/switches/ps646/products_configuration_example09186a0080169623.sht ml#concept2) section of this document.

Issue the archive download-sw command in order to copy over the .tar file and extract all the files inside the .tar file.
There are two options to consider with this command:
/leave-old-sw
If you choose to leave the current version of software as a backup, the command syntax is archive download-sw /leave-old-sw tftp://tftp_server_ip/file_name . As Step 5 discusses, be sure that you have enough space in Flash to use this option.
/overwrite
If you choose to overwrite or replace the current version of software with the newer version, the command syntax is archive download-sw /overwrite tftp://tftp_server_ip/file_name . This document uses this overwrite option. The upgrade procedure is exactly the same despite the option you choose, but the results differ.
Note: There are additional options that this document does not cover. For details, refer to Working with the IOS File System, Configuration Files, and Software Images (http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.1_13_ea1/configuration/guide/swiosfs.html) for your release of 3550 software.

Confirm that the archive download-sw command with the /overwrite option automatically configures a boot system statement.
With a boot system statement, the new image boots on the next reload of the switch. In order to confirm the configuration of a boot system statement, issue the show boot command.
Here is a sample command output:
3550# show boot
BOOT path-list: flash:c3550-i5q3l2-mz.121-13.EA1/c3550-i5q3l2-mz.121-13.EA1.bin
!--- Output suppressed.
If for some reason the configuration of the boot statement does not occur, you can configure the statement. Issue the boot system command.
Here is a sample command output:
3550# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
3550(config)# boot system flash:c3550-i5q3l2-mz.121-13.EA1/
c3550-i5q3l2-mz.121-13.EA1.bin
!--- Note: This command should be on one line.
!--- You use the directory/file name to set the boot system statement.
3550(config)# end
3550#
Issue the write memory command in order to save your changes and reload the switch.
Here is a sample command output:
3550# write memory
Building configuration...
[OK]
3550# reload
Proceed with reload? [confirm]
!--- Press Return or Enter.
00:56:01: %SYS-5-RELOAD: Reload requested

Press RETURN to get started!
!--- Press Return or Enter.
Issue the show version command in order to verify that you run the new image.
Here is a sample command output:

The Software Upgrade Procedure for 3550 Series Switches (http://www.cisco.com/en/US/products/hw/switches/ps646/products_configuration_example09186a0080169623.sht ml#configure2) section of this document provides the commands necessary in order to verify that your configuration works properly.
Troubleshoot
This section provides information you can use to troubleshoot your configuration.
Image Transfer from TFTP Server Fails
If you find that image transfer from the TFTP server fails continuously, refer to this document:
Common Problems in Installing Images Using TFTP or an RCP Server (http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/products_qanda_item09186a00800a775f.shtml)The document provides known issues with the TFTP server.
Software Upgrade Fails, Switch: Prompt Displays, or Switch Reboots Continuously
Your software upgrade can fail for a number of reasons. For example, IP connectivity problems can exist between the switch and TFTP server, or you can have incorrectly set the boot statements. These issues can cause your switch to boot in the switch: mode. If your 3550 displays the switch: prompt or continuously reboots, refer to this document for software recovery procedures:
Recovery From Corrupt or Missing Software Image on Cisco Catalyst 2900XL and 3500XL Series Switches (http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a0080094955.shtml) Switch Does Not Boot Automatically, Needs a Manual Boot at the ROMMON (switch: Prompt)
If you find that your switch does not boot automatically and needs a manual boot, refer to this document for manual boot at the ROMMON (switch: prompt):
The Switch Not Booting Automatically, Needs a Manual Boot at the ROMMON (switch: Prompt) (http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a00800946e5.shtml#switch_no t_auto) section of the document Upgrading Software in Catalyst 2900XL and 3500XL Switches Using the Command Line Interface (http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a00800946e5.shtml) You Receive the Error_Bad_Mzip Error Message
You see this error when the Cisco IOS image is corrupt or a .tar file uploads through an Xmodem. In order to resolve the issue, complete these steps:
Upload the .bin file to the switch through the Xmodem.
Set the boot path to the correct file name.
Reload the switch.
Check that the image file size is the correct one.
If the image file size is not correct, try to download the image file again.Refer to these documents to check the recovery procedure:
The Recovering from Corrupted Software (http://www.cisco.com/en/US/docs/switches/lan/catalyst2900xl_3500xl/release12.0_5_xu/scg/kitrbl.html#wp1034718) section of Troubleshooting (http://www.cisco.com/en/US/docs/switches/lan/catalyst2900xl_3500xl/release12.0_5_xu/scg/kitrbl.html)
The Step-by-Step Recovery Procedure (http://www.cisco.com/en/US/products/hw/switches/ps628/products_tech_note09186a0080169696.shtml#topic2) section of Recovering Catalyst Fixed Configuration Switches from a Corrupted or Missing Image (http://www.cisco.com/en/US/products/hw/switches/ps628/products_tech_note09186a0080169696.shtml) After the Upgrade the Switch Does not Boot and Moves to EMU Prompt
The prompt occurs due to corrupt software or some problem during the download.
In order to recover from the "EMU>" prompt, complete these recovery steps:
Reload the switch, and then press the mode button in order to force the switch to ROMMON.
Perform the ROMMON recovery with the procedure in the Recover from ROMmon Mode (http://www.cisco.com/en/US/products/hw/switches/ps663/products_configuration_example09186a0080094ecf.sht ml#rommon) section of Recover a Cisco IOS Catalyst 4500/4000 Series Switch from a Corrupt or Missing Image or in Rommon Mode. (http://www.cisco.com/en/US/products/hw/switches/ps663/products_configuration_example09186a0080094ecf.sht ml)
Note: Xmodem recovery is not supported when the switch is in the "EMU>" prompt. The only command that can be executed at the EMU prompt is dir flash:. If any other command is executed at the EMU prompt, the switch dispalys a no response from remote system message from the hyperterminal.
