Introduction

This document explains the step-by-step procedure for upgrading the software image on Catalyst 3550 series switches using the Command Line Interface (CLI).

This document does not cover the upgrade procedure using the Cluster Management Suite (CMS). For detailed instructions on this procedure, launch the CMS application, select Administration > Software Upgrade, and select Help from the menu bar.

A software image upgrade may be necessary for many reasons:

*

You want to implement new features in your network that are available in the new software release.
*

You want to install a new line card that is not supported by the current software version.
*

Your switch has been affected by a known bug that is resolved in the next software release.

Conventions

For more information on document conventions, see the Cisco Technical Tips Conventions.
Prerequisites

If you are not already familiar with Catalyst 3550 naming conventions, feature sets, file systems and boot parameters, or how to setup a TFTP server and backup your configuration, it is recommended that you read the Preparing to Upgrade section of this document before attempting the software upgrade.

Otherwise, you can skip any or all of theses topics and go directly to the Software Upgrade Procedure for 3550 Series Switches section of this document.
Components Used

This document is not restricted to specific software and hardware versions.

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.
Preparing to Upgrade
Understanding File Extensions: bin vs tar files

There are two types of files or file extensions you will see when downloading 3550 software from the LAN Switching software page of the Software Center (registered customers only) :

*

The .bin file is the IOS image. If you only want to use the CLI to manage the switch, this is the only file you will need to download.
*

The .tar file is an archive file from which both the IOS image and the CMS files are extracted during the upgrade process. If you want to manage switches or clusters of switches through a web interface (HTML), this is the only file you need to download.

Note: When you download a .tar image, the file will be saved by whatever archive utility is installed on your PC. This could be WinZip or some other third-party software. There is no need to manually extract the archived files. This will be done automatically during the upgrade process.

Note: For more information on the CMS, refer to the Multimedia Presentation .
Understanding 3550 Software Image Naming Conventions: SMI vs EMI

The 3550 is either a Layer 2 (L2) or Layer 3 (L3) switch, depending on the software version and feature set you install.

The naming conventions for 3550 images begin with either of the following:

The differences between the two are explained below.

*

The SMI image is essentially a L2 only image. In software version 121-8.EA1b, however, enhancements to the L2 feature set were made. Consequently, you may see the term Layer2+ used for this and later SMI releases. In software version 121-11.EA1, basic L3 functionality was added to the SMI image with static unicast routing, the Routing Information Protocol (RIP), and other features. Consequently, you will see the phrase basic Layer 3 routing features used for this and later SMI releases.
*

The EMI image is a L2 image combined with a full L3 feature set, including Interior Gateway Routing Protocol (IGRP) and Enhanced IGRP (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP) Version 4, Hot Standby Router Protocol (HSRP), Protocol-Independent Multicast (PIM), and other advanced services.

Note: For more information on SMI and EMI features, please refer to the Catalyst 3550 Multilayer Switch Software Configuration Guide under the Release Notes for your version of 3550 software.

Note: All Catalyst 3550 Gigabit Ethernet (GE) switches are shipped with the EMI installed. Catalyst 3550 FastEthernet switches are shipped with either the SMI or the EMI installed. You can order the Enhanced Multilayer Software Image Upgrade kit (CD-3550-EMI=) to upgrade any Catalyst 3550 FastEthernet switch from the SMI to the EMI. Keep in mind, however, that unless your 3550 was purchased with the EMI image pre-installed, you must purchase the upgrade kit before downloading the EMI image.

You can verify which version of software you are are running, where the image is installed, which feature set you are running, and the model of 3550 you have by issuing the show version command. A sample command output is shown below.

Understanding the 3550 Flash File System and Memory Requirements
3550 Flash File System

The 3550 ships from the factory with a CMS image (.tar file) installed in the flash: directory. The extraction process that takes place with a .tar file creates an IOS image directory that has the same name as the IOS image (.bin file), but without the file extension. The IOS image (.bin file) is stored in this directory along with an HTML subdirectory that contains the CMS files.

You can view the 3550 Flash file system by issuing the dir flash: command. A sample command output is shown below.

3550#dir flash:
Directory of flash:/
2 -rwx 796 Mar 01 1993 00:00:36 vlan.dat
3 -rwx 0 Mar 01 1993 00:04:17 env_vars
4 -rwx 1637 Mar 07 1993 14:34:06 config.text
5 -rwx 348 Mar 01 1993 00:04:17 system_env_vars
6 -rwx 5 Mar 07 1993 14:34:06 private-config.text
7 drwx 192 Mar 01 1993 00:18:55 c3550-i5q3l2-mz.121-12c.EA1


!--- Notice the d in the permissions indicating that
!--- c3550-i5q312-mz.121-12c.EA1 is a directory.
!--- This is where both the IOS image (.bin file) and
!--- the HTML subdirectory are located.

15998976 bytes total (10415104 bytes free)

If you upgrade using just the IOS image (bin file), you will issue the copy tftp command, which is fully explained in the Step-by-Step Procedure for the 3550 using only the IOS image (.bin file) section of this document.

If you upgrade using the CMS image ( .tar file), you will issue the archive download-sw command, which is fully explained in the Step-by-Step Procedure for the 3550 using the CMS image (.tar file) section of this document.
3550 Memory Requirements

DRAM Memory

The SDRAM configuration on all 3550s is 64 MB. There are no minimum DRAM requirements to consider before upgrading software on the 3550.

FLASH Memory

All 3550s have 16 MB of internal Flash memory. The Flash memory is not upgradeable.

You can only store a limited number of images in Flash. Always check the size (in bytes) of the image on the LAN Switching Software page of the Software Center (registered customers only) before upgrading software. Compare the size of this image with the free space in Flash by issuing the dir flash: command. A sample command output is shown below.

3550#dir flash:
Directory of flash:/
2 -rwx 796 Mar 01 1993 00:00:36 vlan.dat
3 -rwx 346 Mar 01 1993 00:21:36 system_env_vars
6 drwx 192 Mar 01 1993 00:21:34 c3550-i5q3l2-mz.121-13.EA1
7 drwx 192 Mar 01 1993 00:18:55 c3550-i5q3l2-mz.121-12c.EA1
42 -rwx 0 Mar 01 1993 00:21:35 env_vars
15998976 bytes total (4416512 bytes free)


!--- This is the free memory in Flash.

If necessary, issue the delete flash: <filename> command to delete a single IOS image (.bin file), or the delete /force /recursive command to delete a directory and all the files in it.

If you are upgrading using a CMS image (.tar file), the upgrade procedure uses the archive download-sw command. This command has a few options, including archive download-sw /overwrite, which overwrites or replaces the old software, and archive download-sw /leave-old-sw, which leaves the old software, but consequently requires more Flash space.

Issuing the delete command and the archive download-sw command are covered in detail in the Software Upgrade Procedure for the 3550 Series Switches section of this document.
Changing the Config-Register and Setting Boot Statements

Unlike some other Catalyst switches, there is no config-register command on the 3550. The configuration register value cannot be changed from the default.

The 3550 will automatically search for a valid software image to boot from, even if a boot system statement is not set. It is still recommended, however, to set the boot statement anyway as a precaution. The command to set a boot system statement is boot system flash:<filename> .

Multiple images can be specified in the boot statement by separating them with a semicolon. The command would be boot system flash:<file1;file2>

If you are using a CMS image on the 3550, the IOS image (.bin file) will be extracted into its own directory. The boot system command becomes boot system flash:<directory/filename> .

Issuing the boot system command is covered in detail in the Software Upgrade Procedure for the 3550 Series Switches section of this document.
Download Software Image

The 3550 software image must be downloaded onto the PC that will act as the TFTP server prior to actual image upgrade. Download the software image from the LAN Switching Software section of the Software Center (registered customers only) . To download the software image, you must be a registered user and you must be logged in. If you do not understand which image to download, review the Preparing to Upgrade section of this document.
Install TFTP Server

For sample output for this document, a third-party TFTP server is installed on a PC running Microsoft Windows 2000 Professional. You can use any TFTP server installed on any platform. It is not necessary that you use a PC with a Windows OS.

1.

Download and install any shareware TFTP software from the Internet on the PC that you will be using to copy the 3550 software image to the switch. The TFTP server root directory must be the directory to which the software image is downloaded. You can download the images to the default root directory of the TFTP server or change the root directory path to the directory in which the software image is stored.
2.

Access the switch CLI by connecting a console cable between the switch console port and the PC. Refer to Connecting a Terminal to the Console Port on Catalyst Switches to access the CLI using the hyperterminal.

Note: The switch can be upgraded using remote Telnet access. You will, however, loose Telnet connectivity when the switch is reloaded during the software upgrade. The Telnet can be re-established once it is loaded with the new image, however, to troubleshoot in case of failure, it is essential to have local console access. A switch upgrade using console access is preferred.
3.

For best results, configure a VLAN interface on the switch to be in the same VLAN (subnet) as your directly connected TFTP server. If it is not possible to have your TFTP server directly connected to the switch, issue either the ip default-gateway or the ip route command to set a default gateway to reach the TFTP server.

On the 3550, you can configure a VLAN interface with an IP address and with L2 physical interfaces as members of that VLAN. Alternately, you can configure a physical interface as a L3 interface with its own IP address, similar to a router.

In the example below, a VLAN interface with a FastEthernet L2 physical interface in that VLAN is used. In this example, the 3550 and TFTP server are not in the same subnet, so a default route is configured.

3550#conf t
3550(config)#int vlan 1


!--- A FastEthernet interface is in VLAN 1.

3550(config-if)#ip address 10.10.10.1 255.255.255
3550(config-if)#no shut
3550(config-if)#exit
3550(config)#ip route 0.0.0.0 0.0.0.0 10.10.10.129


!--- Issue this command as one way to establish
!--- connectivity to a TFTP server on a different subnet or network.

3550(config)#end
3550#
3550#ping 20.20.20.2


!--- Ping the IP address of the TFTP server
!--- from the switch to verify connectivity.

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 20.20.20.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/202/1000 ms
3550#

Backup Configuration and Software Image

Perform a backup of the switch configuration to the PC running TFTP server. If you loose the switch configuration for any reason, you can always restore it from the TFTP server.

Issue the copy startup-config tftp command on the 3550 to back up your current configuration to a TFTP server. A sample command output is shown below.

3550#copy startup-config tftp
Address or name of remote host []? 20.20.20.2


!--- Type your TFTP server IP.
!--- Press Return or Enter.

Destination filename [3550-confg]?


!--- Press Return or Enter.
!--- The file 3550-confg will be saved in the
!--- TFTP server root directory.

Software Upgrade Procedure for 3550 Series Switches

There are two upgrade procedures available for the 3550:

1.

If you want to use the CLI only and do not intend to use Cisco's CMS software, follow the Step-by-Step Procedure for the 3550 using only the IOS image (.bin file) .
2.

If you want to use the latest version of Cisco's CMS software, follow the Step-by-Step Procedure for the 3550 using the CMS image (.tar file).

Note: For more information on the CMS, refer to the Multimedia Presentation.
Step-by-Step Procedure for the 3550 using only the IOS image (.bin file)

For this example, the software on a 3550 is upgraded from version 12.1(12c)EA1 to version 121-13.EA1 using only the IOS image (.bin file). The procedure is the same no matter which version of software you use.

1.

Issue the show version command to view the current version of software that you are running. A sample command output is shown below.

3550#sh ver
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 12.1(12c)EA1.

2.

Go to the LAN Switching Software section of the Software Center (registered customers only) .

Select Catalyst 3550 software and find the image you want to download. Note the size of the image in bytes. In this example, the c3550-i5q3l2-mz.121-13.EA1.bin file is used. The i5q3l2 in the beginning of the filename tells us this is an EMI. The image size is 3993612 bytes, or approximately 4 MB. Download the image you want.

Note: The upgrade procedure is the same for the SMI. The SMI image has i9q3l2 in the beginning of the filename. It is a smaller image and will take up less room in Flash. If you still have questions about whether to use an SMI or EMI image, refer to the Understanding 3550 Software Image Naming Conventions: SMI vs EMI section of this document.
3.

Issue the dir flash: command on the 3550 to verify how much free memory you have for the upgrade. A sample command output is shown below.

3550#dir flash:
Directory of flash:/
2 -rwx 556 Mar 01 1993 00:02:13 vlan.dat
3 -rwx 3384393 Mar 01 1993 0058 c3550-i5q3l2-mz.121-9.EA1c.bin
4 drwx 192 Mar 01 1993 00:10:15 c3550-i5q3l2-mz.121-11.EA1a


!--- Notice the d for dir4ectory in the permissions statement.

38 -rwx 0 Mar 01 1993 00:10:15 env_vars
7 -rwx 348 Mar 01 1993 00:10:15 system_env_vars
12 drwx 192 Mar 01 1993 00:16:22 c3550-i5q3l2-mz.121-12c.EA1


!--- Notice the d for directory in the permissions statement.

15998976 bytes total (1949184 bytes free)


!--- There is just under 2 MB of memory left, which is not enough.
!--- One of the old images or possibly a directory will
!--- have to be deleted in order to upgrade.

3550#

Note: If you already have enough room in Flash for the upgrade, you can proceed directly to Step 5 .
4.

Issue the delete command to remove the old 121-9.EA1c IOS image (.bin file). This will free up enough room for the upgrade. A sample command output is shown below.

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.

3550#
3550#dir flash:
Directory of flash:/
2 -rwx 556 Mar 01 1993 00:02:13 vlan.dat
4 drwx 192 Mar 01 1993 00:10:15 c3550-i5q3l2-mz.121-11.EA1a
38 -rwx 0 Mar 01 1993 00:10:15 env_vars
7 -rwx 348 Mar 01 1993 00:10:15 system_env_vars
12 drwx 192 Mar 01 1993 00:16:22 c3550-i5q3l2-mz.121-12c.EA1
15998976 bytes total (5334016 bytes free)


!--- After deleting the old IOS image file, there is now over
!--- 5 MB of free memory. This is enough for the upgrade.

3550#

You may need to free up even more space for an upgrade depending on how many images you have stored in Flash. You can delete an old image directory to accomplish this.

Note: Keep in mind this is where the old IOS image (.bin file) as well as the files needed for the CMS are stored. If you do not use the web interface to manage the switch or you have a newer image directory, this is not a problem.

Issue the delete /force /recursive command to delete an image directory and all the subdirectories and files in it. A sample command output is shown below.

3550#delete /force /recursive flash:c3550-i5q3l2-mz.121-11.EA1a
Delete filename [c3550-i5q3l2-mz.121-11.EA1a]?


!--- Press Return or Enter.

3550#
3550#dir flash:
Directory of flash:/
2 -rwx 556 Mar 01 1993 00:02:13 vlan.dat
38 -rwx 0 Mar 01 1993 00:10:15 env_vars
7 -rwx 348 Mar 01 1993 00:10:15 system_env_vars
12 drwx 192 Mar 01 1993 00:16:22 c3550-i5q3l2-mz.121-12c.EA1
15998976 bytes total (10417664 bytes free)


!--- Freeing up more room was not necessary in this case,
!--- however, you can see you now have over 10 MB of free space.

3550#

5.

Perform the upgrade by issuing the copy tftp flash: command.

3550#copy tftp flash:
Address or name of remote host []? 20.20.20.2


!--- This is TFTP server IP. Press Return or Enter.

Source filename []? c3550-i5q3l2-mz.121-13.EA1.bin

This completes the upgrade procedure on a 3550 using only the IOS image (.bin file).

Step-by-Step Procedure for the 3550 using the CMS image (.tar file)

For this example, the software on a 3550 is upgraded from version 12.1(12c)EA1 to verison 121-13.EA1 using the CMS image (.tar file).

1.

Issue the show version command to view the current version of software that you are running. A sample command output is shown below.

3550#sh ver
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 12.1(12c)EA1.

2.

Go to the LAN Switching Software section of the Software Center (registered customers only) .

Select Catalyst 3550 software and find the image you want to download. Note the size of the image in bytes. In this example, the c3550-i5q3l2-tar.121-13.EA1.tar file is used. The i5q3l2 in the beginning of the filename tells us this is an EMI. The image size is 6011904 bytes or approximately 6 MB. Download the image you want.

Note: The upgrade procedure is the same for the SMI. The SMI image has i9q3l2 in the beginning of the filename. It is a smaller image and will take up less room in Flash. If you still have questions about whether to use an SMI or EMI image, refer to the Understanding 3550 Software Image Naming Conventions: SMI vs EMI section of this document.
3.

Issue the dir flash: command on the 3550 to verify how much free memory you have for the upgrade. A sample command output is shown below.

3550#dir flash:
Directory of flash:/
2 -rwx 556 Mar 01 1993 00:00:35 vlan.dat
3 -rwx 3384393 Mar 01 1993 1937 c3550-i5q3l2-mz.121-9.EA1c.bin


!--- Notice there is one IOS image (.bin file) and
!--- two image directories installed.

!--- Notice the d in the permissions indicating that these are directories.
!--- These directories contain the IOS image(.bin file) and CMS files,
!--- which were extracted from the .tar image during the upgrade.

38 -rwx 316 Mar 01 1993 1933 system_env_vars
15998976 bytes total (1948160 bytes free)


!--- There is under 2 MB of free memory in Flash, which
!--- may not be enough for the upgrade.

3550#

Note: If you already have enough room in Flash for the upgrade, you can proceed directly to Step 5 .
4.

If you need to free up memory on the 3550, you have the following options:
*

If you do not want to keep the current version of software, you can overwrite or replace it during the upgrade procedure. Proceed to Step 5 if this is what you want to do.
*

If you want to leave the current version of software as a backup, you may need to manually delete an older image or directory.

If you want to leave the current version of software, and you do not have enough space in Flash, issue the delete command to remove an old IOS image or directory in order to make room for the upgrade. A sample command output is shown below.

3550#delete flash:c3550-i5q3l2-mz.121-9.EA1c.bin
Delete filename [c3550-i5q3l2-mz.121-9.EA1c.bin]?


!--- Press Enter or Return.

Delete flash:c3550-i5q3l2-mz.121-9.EA1c.bin? [confirm]


!--- Press Enter or Return.

3550#
3550#dir flash:
Directory of flash:/
2 -rwx 556 Mar 01 1993 00:00:35 vlan.dat
4 -rwx 1595 Mar 01 1993 1941 config.text
5 -rwx 0 Mar 01 1993 1933 env_vars
8 drwx 192 Mar 01 1993 19:42:50 c3550-i5q3l2-mz.121-11.EA1


!--- Notice the d in the permissions indicating these are directories.

12 drwx 192 Mar 01 1993 00:16:22 c3550-i5q3l2-mz.121-12c.EA1
38 -rwx 316 Mar 01 1993 1933 system_env_vars
15998976 bytes total (5332992 bytes free)


!--- In this case, although additional memory is
!--- created by deleting an old IOS image (.bin file),
!--- there is still not enough free memory for the new 6 MB image.
!--- You will need to delete one of the image directories.

3550#

The image directory on a 3550 is where the IOS image (.bin file) and the CMS files are extracted from the .tar image and installed during the upgrade. The image directory is named with the IOS image name (excluding the .bin extension). A sample command output is shown below.

3550#dir c3550-i5q3l2-mz.121-11.EA1
Directory of flash:/c3550-i5q3l2-mz.121-11.EA1/
9 drwx 704 Mar 01 1993 19:40:57 html


!--- The html subdirectory contains the CMS files
!--- needed for web management.

36 -rwx 3703698 Mar 01 1993 19:42:50 c3550-i5q3l2-mz.121-11.EA1.bin


!--- This is the IOS image (.bin file) for this image directory.

37 -rwx 252 Mar 01 1993 19:42:50 info
15998976 bytes total (5332992 bytes free)
3550#

Issue the delete /force /recursive command to delete an image directory and all the files in it. A sample command output is shown below.

3550#delete /force /recursive c3550-i5q3l2-mz.121-11.EA1
Delete filename [c3550-i5q3l2-mz.121-11.EA1]?


!--- Press Enter or Return.

3550#
3550#dir flash:

38 -rwx 316 Mar 01 1993 1933 system_env_vars
15998976 bytes total (10415616 bytes free)


!--- There is now enough room to proceed with the upgrade.

5.

Issue the archive download-sw command to copy over the .tar file and extract all the files inside it.

There are two options to consider with this command. The options are /leave-old-sw or /overwrite.

The upgrade procedure is exactly the same no matter which option you choose, but the results are different.

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>/<filename> . As discussed in Step 4, make sure you have enough space in Flash to use this option.

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>/<filename> . This is the option used in this document.

Note: There are other options that can be used in addition to these, however, they are not covered in this document. For more details, refer to Working with the IOS File System, Configuration Files, and Software Images for your release of 3550 software.

Issue the dir flash: command. A sample command output is shown below.

3550#dir flash:
