This document describes the steps to upgrade the software image on Cisco Catalyst 3750 series switches with the command-line interface (CLI).
Cisco recommends that before you download software, refer to these sections of Release Notes for the Catalyst 3750, 3560, and 2970 Switches, Cisco IOS® Release 12.2(25)SEB and Later for important information:
The information in this document is based on these hardware versions:
WS-C3750G-12S switches
WS-C3750G-24TS switches
Note: You can substitute any stackable Catalyst 3750 series switch.
Note: This document serves as a reference for platforms like Catalyst 3750 switches, which have reached the end of their life cycle. Although these platforms are being replaced by newer devices, the information contained herein remains valuable for reference purposes.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Refer to the Cisco Technical Tips Conventions for more information on document conventions.
A directory that has the Cisco IOS Software release name stores the Cisco IOS image as a bin file. The directory stores the image on the system board flash device (flash:). A subdirectory contains the files that you need for web management.
You can use the show version
privileged EXEC command in order to see the software version that runs on your switch. The second line of the display shows the version.
Note: Although the show version
output always shows the software image that runs on the switch, the model name that appears at the end of this display is the factory configuration. This image is either the IP base image, formerly known as the standard multilayer image (SMI), or the IP services image, formerly known as the enhanced multilayer image (EMI). This name does not change if you upgrade the software image.
You can also use the dir filesystem: privileged EXEC
command. This command shows the directory names of any other software images that you have stored in flash memory.
Before you decide the Cisco IOS Software release to which you want to upgrade the switches, you must:
Read the Release Notes of the particular Cisco IOS Software release. Refer to Cisco Catalyst 3750 Series Switches - Release Notes.
Refer to the Bug Toolkit (registered customers only) and Cisco Catalyst 3750 Series Switches - Field Notices.
Priority value determines the primary switch in a stack. The priority value can be 1 to 15. The default priority value is 1. Cisco recommends that you assign the highest priority value to the switch that you prefer to be the stack primary. In this example, the primary switch has a priority value of 15. For more information, refer to Creation and Management of Catalyst 3750 Switch Stacks.
3750#show switch detail Current Switch# Role Mac Address Priority State -------------------------------------------------------- 1 Slave 000c.30ae.4f00 9 Ready *2 primary 000d.bd5c.1680 15 Ready
The software download center for Catalyst 3750 contains two sets of Cisco IOS images for every feature set and versions. One set contains only the Cisco IOS image file which has the extension .bin. The other set contains the Cisco IOS image plus the web-based device manager which has the extension .tar.
This document explains the upgrade procedure with the .tar image as well as with the .bin image. The .tar file contains the Cisco IOS image file and the files that you need for the embedded device manager. You must use the combined tar file in order to upgrade the switch through the device manager.
Cisco IOS Software Release 12.2(25)SEA and earlier referred to the image that provides Layer 2+ features and basic Layer 3 routing as the SMI. These software releases referred to the image that provides full Layer 3 routing and advanced services as the EMI.
Cisco IOS Software Release 12.2(25)SEB and later refer to the SMI as the IP base image and the EMI as theI P services image.
Table 1 lists the different file-naming conventions for releases earlier than and later than Cisco IOS Software Release 12.2(25)SEB.

Flash File System
The 3750 ships from the factory with the installation of a web-based device manager (.tar file) in the flash: directory. The extraction process that takes place with a .tar file creates a Cisco IOS image directory. The image directory has the same name as the Cisco IOS image (.bin file), but without the file extension. This directory stores the Cisco IOS image (.bin file) along with an HTML subdirectory that contains the device manager files.
Issue the dir flash:
command in order to view the 3750 Flash file system. Here is a sample command output:
3750#dir flash: Directory of flash:/ 2 -rwx 5684228 Mar 12 1993 08:13:57 +00:00 c3750-ipbase-mz.122-25.SEC2.bin 3 -rwx 2105 Mar 1 1993 00:02:16 +00:00 config.text 4 drwx 192 Mar 12 1993 08:11:00 +00:00 c3750-ipbase-mz.122-25.SEB4 5 -rwx 5 Mar 1 1993 00:02:16 +00:00 private-config.text 6 -rwx 856 Mar 1 1993 00:04:40 +00:00 vlan.dat 364 -rwx 105 Mar 12 1993 08:11:00 +00:00 info 15998976 bytes total (3201536 bytes free) !--- Notice the "d" in the permissions statement. !--- It indicates that c3750-ipbase-mz.122-25.SEB4 is a directory. !--- This directory is the location of both the Cisco IOS image (.bin file) !--- and the HTML subdirectory.
Refer to these sections in this document in order to upgrade the 3750 switch to a Cisco IOS Software release with a web-based device manager:
3750 Series Switch Stack Cisco IOS Upgrade - Automatic (.tar image)
3750 Series Switch Stack Cisco IOS Upgrade - Manual (.tar image)
Refer to the 3750 Series Switch Stack Cisco IOS Upgrade - Manual (.bin Image) section in order to upgrade the switch with just a Cisco IOS Software release.
DRAM Memory
All models of 3750 series switches have a DRAM configuration of 128 MB. There are no minimum DRAM requirements to consider before you upgrade software on the 3750.
Flash Memory
The internal Flash memory shipped with the 3750 switches are either 16 MB or 32 MB based on the model of the Catalyst 3750 switch. Refer to the Cisco Catalyst 3750 Data Sheet for more information.
There is a limit to the number of images that you can store in Flash. Always check the image size, in bytes, before you upgrade the software. Issue the dir flash:
command in order to compare the size of this image with the free space in Flash. Here is a sample command output:
3750#dir flash: Directory of flash:/ 2 -rwx 6221372 Mar 1 1993 00:23:06 +00:00 c3750-ipbase-mz.122-25.SED1.bin 3 -rwx 2105 Mar 1 1993 00:02:16 +00:00 config.text 4 -rwx 5684228 Mar 1 1993 01:17:34 +00:00 c3750-ipbase-mz.122-25.SEC2.bin 5 -rwx 5 Mar 1 1993 00:02:16 +00:00 private-config.text 6 -rwx 856 Mar 1 1993 00:04:40 +00:00 vlan.dat 15998976 bytes total (4087296 bytes free) 3750#
If necessary, issue the delete flash:file_name
command in order to delete a single Cisco IOS image (.bin file). Or issue the delete /force /recursive flash:dir_name
command in order to delete a directory and all the files in the directory.
Here is a sample command output to delete a Cisco IOS image (.bin file):

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 older images/directory to free up this space.
In this section, you are presented with the information to configure the features described in this document.
The procedure in this section copies the combined tar file to the switch. You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace the current image, or you can keep the current image.
Note: For switch stacks, the archive download-sw and archive upload-sw privileged EXEC commands can only be used through the stack primary. Software images downloaded to the stack primary are automatically downloaded to the rest of the stack members. Thus, you must be logged on to the primary switch to perform this upgrade.
In order to download software, complete these steps:
Step 1
Use the Decide Which Files to Use section of this document in order to identify the type of image and feature set that you want to download.
Step 2
In order to download older versions of the IP services image or IP base image files for a Catalyst 3750 switch, click Archived Catalyst 3750 Software . In order to obtain authorization and to download the cryptographic software files, click Catalyst 3750 Strong Cryptographic (3DES) Software.
Note: Cisco IOS Software releases earlier than Cisco IOS Software Release 12.1(19)EA1c include a boot loader upgrade. The boot loader can take up to 1 minute to upgrade the first time that you load the new software. Do not power cycle the switch while the boot loader upgrades.
Step 3
Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP server has the proper configuration.
For more information, refer to Appendix B of the software configuration guide for this release.
Step 4
Log in to the switch through the console port or a Telnet session and enter enable mode.
Step 5
In order to view the current version, issue the show version
command.

Step 6
Issue the dir flash:
command on the 3750 in order to verify the amount of free memory that you have for the upgrade.
Here is a sample command output:
3750#dir flash: Directory of flash:/ 2 -rwx 1516 Mar 01 1993 00:01:28 vlan.dat 3 -rwx 4050902 Mar 01 1993 00:03:32 c3750-i5-mz.121-19.EA1d.bin 4 -rwx 4273 Mar 05 1993 19:22:44 config.text 84 -rwx 5 Mar 05 1993 19:22:44 private-config.text 15998976 bytes total (11940352 bytes free)
Step 7
In order to verify connectivity to the TFTP server, ping its IP address.
3750#ping 10.11.11.11 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.11.11.11, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
Step 8
There are several options for the download of the image. You can use the command-line options that appear in this section to have a new image overwrite the old image or leave the old image in flash.
The example uses the archive download-sw
command in order to retain the old image on the device. For a complete description of the commands available, refer to the archive download-sw section of the Catalyst 3750 Switch Cisco IOS Commands guide.
Here are the options available for the archive download-sw
command:
3750#archive download-sw ? /destination-system specify destination system to receive software /force-reload Unconditionally reload system after successful sw upgrade /imageonly Load only the Cisco IOS image(s) /leave-old-sw Leave old sw installed after successful sw upgrade /no-set-boot Don't set BOOT -- leave existing boot config alone /no-version-check skip version check that prevents incompatible image install /only-system-type specify individual system type to be updated /overwrite OK to overwrite an existing image /reload Reload system (if no unsaved config changes) after successful sw upgrade /safe Always load before deleting old version flash1: Image file flash2: Image file flash: Image file ftp: Image file rcp: Image file tftp: Image file

!--- in the flash of all switches in the stack. In this example, installation
!--- is complete in both switches.
Step 9
The image copy is complete, and you are ready for the reboot. In order to verify that the current state of the switches is Ready , issue the show switch detail
command.
Here is an example:
3750#show switch detail Current Switch# Role Mac Address Priority State -------------------------------------------------------- 1 Slave 000c.30ae.4f00 9 Ready *2 primary 000d.bd5c.1680 15 Ready Stack Port Status Neighbors Switch# Port 1 Port 2 Port 1 Port 2 -------------------------------------------------------- 1 Ok Ok 2 2 2 Ok Ok 1 1
Step 10
In order to verify that the new image is in flash for the stack members, issue the dir flash:
command and the dir flash 1:
command. In this example, there are two switch stack members. If the stack configuration includes additional switches in the stack, issue the dir flash#:
command for each additional switch in the stack.
Issue the show version
command in order to verify that the old image is still the current operation system image. Issue the show boot
command in order to verify that the new image is now the image in the BOOT path-list that can load at the next switch reload.

The previous section of this document explained how to upgrade Cisco IOS with the archive download-sw
command. You can also upgrade the Cisco IOS manually switch-by-switch and not disconnect the stack cables. The three major steps in this method are:
Copy the .tar image from the TFTP server to the primary switch.
Extract the .tar image into all the Flash file systems of the switches.
Configure the boot variable.
The archive download-sw
command does all three steps throughout the automatic Cisco IOS upgrade. You can also perform these three steps in a manual Cisco IOS upgrade. The step-by-step section shows an example of how to upgrade to Cisco IOS Software Release 12.2(25)SEE1. This example has a switch stack with three switches. Switch 1 is the primary switch and switches 2 and 3 are the member switches.
Step 1 - Download the .tar Image.
You need to make sure you have sufficient space available in the Flash of the primary switch. The primary switch must have twice the amount of space of the .tar image file size. This space is needed to store the .tar file as well as to store the content of the .tar file that you extract next in Step 2. For example, if the .tar image size is 10 Mb, you need to have a minimum of 20 Mb of free space.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!--- Output is suppressed.
Step 2 - Extract the .tar Image.
Extract the .tar images to all the switches in the Flash file system. The archive tar /xtract
command creates a directory and extracts the files under the newly created directory.
This is an example of the command syntax:
3750-stack#archive tar /xtract <tar file name> <Dir to extract files>
Complete these sub-steps:
Extract the .tar file into the Flash on switch1.
3750-stack#archive tar /xtract c3750-advipservicesk9-tar.122-25.SEE1.tar flash1: extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/grn_vertlines_bott.gif (957 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/red.gif (147 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/print.gif (625 bytes) !--- Output is suppressed.
Extract the .tar file into the Flash on switch2.

Extract the .tar file into the Flash on switch3.
3750-stack#archive tar /xtract c3750-advipservicesk9-tar.122-25.SEE1.tar flash3: extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/grn_vertlines_bott .gif (957 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/red.gif (147 bytes) extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/print.gif (625 bytes) !--- Output is suppressed.
Step 3 - Configure the Boot Variable.
After you extract the .tar files into the Flash, you need to configure the boot variable to point to the new Cisco IOS. You need to find the path where the .bin file is extracted.
3750-stack#dir Directory of flash:/ 2 drwx192 Mar 11 1993 00:31:05 +00:00 c3750-advipservicesk9-mz.122-25.SEE1 !--- The archive tar /xtract command created this directory. 455 -rwx 114 Mar 11 1993 00:31:05 +00:00 info 457 -rwx 9433 Mar 1 1993 01:40:11 +00:00 config.text 458 -rwx 796 Mar 1 1993 00:02:39 +00:00 vlan.dat 459 -rwx 24 Mar 1 1993 01:40:11 +00:00 private-config.text 15998976 bytes total (5613056 bytes free) 3750-stack#dir flash:c3750-advipservicesk9-mz.122-25.SEE1 Directory of flash:/c3750-advipservicesk9-mz.122-25.SEE1/ 3 -rwx 8169055 Mar 11 1993 00:29:52 +00:00 c3750-advipservicesk9-mz.1 22-25.SEE1.bin 4 drwx 4160 Mar 11 1993 00:30:29 +00:00 html 454 -rwx 709 Mar 11 1993 00:31:05 +00:00 info 15998976 bytes total (5613056 bytes free) 3750-stack#
The boot system switch all
command is used to change the boot variable.
3750-stack(config)#boot system switch all flash:/c3750-advipservicesk9-mz.122-25.SEE1/c3750-advipservicesk9-mz.122-25.SEE1.bin 3750-stack(config)#exit 3750-stack#write memory
Step 4 - Reload and Verify.
Reload the switch and verify that the switch runs the new Cisco IOS software release after the reload:
!--- Reload the switch. Switch#reload Proceed with reload? [confirm] !--- Verify the Cisco IOS software release of the switch after the reload. 3750-stack#show version Cisco IOS Software, C3750 Software (C3750-ADVIPSERVICESK9-M), Version 12.2(25)S E1, RELEASE SOFTWARE (fc1) Copyright (c) 1986-2006 by Cisco Systems, Inc.

A 3750 switch stack can be managed either with the web device manager or with the CLI. If you manage the switch with the CLI, you do not need the .tar image. This section explains the Cisco IOS upgrade with the .bin image. It is assumed that you have already configured the 3750 switch stack with a Cisco IOS image. This section explains how to copy and upgrade the new Cisco IOS in the 3750 switch stack.
Note: The commands archive download-sw
and archive upload-sw
are applicable only for .tar image files and do not apply to .bin image files.
This example explains the step-by-step procedure to upgrade to Cisco IOS Software Release 12.2(25)SEE2 on a Catalyst 3750 switch stack. The Catalyst 3750 switch stack has two switches, and the Cisco IOS image is located at the TFTP server 172.22.1.165. This output shows the stack member and the primary in this stack:
Switch#show switch Current Switch# Role Mac Address Priority State -------------------------------------------------------- 1 Member 0015.63f6.b700 5 Ready *2 primary 0015.c6c1.3000 10 Ready
Step 1 - Download the .bin Image.
Refer to Software Download - Cisco Catalyst 3750 Software and find the image that you want to download. The Software Download Center for the Catalyst 3750 contains two sets of Cisco IOS images for every feature set and versions. One set contains only the Cisco IOS image file which has the extension .bin. The other set contains the Cisco IOS image plus the web-based device manager which has the extension .tar.
Step 2 - Verify the Available Memory.
You can verify the available memory in the Flash file system of both switches individually as this example output shows:
Switch#dir flash1: Directory of flash1:/ 2 -rwx 24 Mar 3 1993 22:02:44 +00:00 private-config.text 3 -rwx 623744 Jan 1 1970 00:12:28 +00:00 stardust0923 4 -rwx 796 Mar 1 1993 00:02:55 +00:00 vlan.dat 5 -rwx 623744 Jan 1 1970 00:32:09 +00:00 diag 6 -rwx 8169055 Mar 1 1993 00:43:34 +00:00 c3750-advipservicesk9-mz. 22-25.SEE1.bin 8 -rwx 10192 Mar 3 1993 22:02:44 +00:00 config.text 462 -rwx 114 Mar 1 1993 00:32:19 +00:00 info 367 drwx 192 Mar 1 1993 00:32:19 +00:00 c3750-advipservicesk9-mz. 22-25.SEE1 32514048 bytes total (12754944 bytes free) Switch#dir flash2: Directory of flash:/ 2 -rwx 4207104 Jan 1 1970 00:14:06 +00:00 c3750-i9-mz.122-20.SE4 3 -rwx 623744 Jan 1 1970 00:17:20 +00:00 stardust0923 4 -rwx 4207104 Jan 1 1970 00:19:44 +00:00ios

In a Catalyst 3750 switch stack, flash: represents the Flash file system of the primary switch. In this example, the dir flash:
command displays the contents of the primary switch (Switch 2) which is flash2:.
Step 3 - Copy the Images to the Flash File System.
Copy the .bin image from the TFTP server to the Flash file system of both switches.
Note: The Automatic Upgrade (auto-upgrade) feature only works with .tar images.
Switch#copy tftp: flash1: Address or name of remote host [172.22.1.165]?

[OK - 8172194 bytes] 8172194 bytes copied in 186.655 secs (43782 bytes/sec)
Step 4 - Configure the Boot Variable.
Configure the boot variable to boot the switch with the newly copied Cisco IOS:
Switch(config)#boot system switch all flash:/c3750-advipservicesk9-mz.122-25.SEE2.bin Switch(config)#exit Switch#write memory
Step 5 - Verify Before the Reload.
Verify the boot variable:
Switch#show boot BOOT path-list : flash:/c3750-advipservicesk9-mz.122-25.SEE2.bin !--- Primary switch.

This section provides information you can use to troubleshoot your configuration.
If you find that an image transfer from the TFTP server fails continuously, refer to Resolving Common Image Installation Problems. This document provides solutions to known issues with the TFTP server.
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 in order to check the recovery procedure:
Step-by-Step Recovery Procedure section of Recover Catalyst Fixed Configuration Switches from a Corrupted Image
Recovering from a Software Failure section of Release Notes for the Catalyst 3750, 3560, and 2970 Switches, Cisco IOS Release 12.2(25)SEB and Later
The switch reports this error message during the software upgrade:
Stack_Switch1#archive download-sw tftp://10.1.1.2/c3750-advipservicesk9-tar.122-25.SEE1.tar Could not buffer tarfile...using multiple downloads examining image... %Error opening tftp://10.1.1.2/c3750-advipservicesk9-tar.122-25.SEE1.tar (Timed out) %Error opening flash:update/info (No such file or directory) ERROR: Image is not a valid Cisco IOS image archive
Complete these steps to identify and resolve the issue:
Make sure you are able to ping the TFTP server IP address from the switch.
Verify your TFTP server works and if possible, try a different TFTP server.
Remove if you have any old information directory from the Flash.
If the error message continues to appear, format the Flash and reload the switch. After you format, the switch can boot into ROMMON mode. If the switch boots into ROMMON mode, then recover the switch with Xmodem.
After the Cisco IOS upgrade, any one or more of the switches do not boot with the new images. Or, when you add a switch to the current stack and the newly added switch has a different Cisco IOS software release than the current switch stack, the new switch is unusable. The 3750 switch stack has a feature called auto-upgrade which is enabled by default. This feature enables the switch stack to automatically upgrade the Cisco IOS on the newly added switch. Sometimes this auto-upgrade fails to upgrade the Cisco IOS of the newly added switch. You see this message sequence when you add the switch to the current stack.

Note: The auto-upgrade feature must be enabled to upgrade the switch in version-mismatch (VM) mode. By default, auto-upgrade is enabled. You can check the status of auto-upgrade with the show boot
privileged EXEC command and the auto upgrade line in the display. You can disable auto-upgrade by with the no boot auto-copy-sw
global configuration command on the stack primary. Refer to Understanding Auto-Upgrade and Auto-Advise for more information.
There are three different methods available to solve the version mismatch problem:
Method 1 - .tar Image
Upgrade the member switch that has an incompatible software image with the archive copy-sw
privileged EXEC command. This command copies the software image from a current stack member to the one with the incompatible software. The affected switch automatically reloads and joins the stack as a fully functioning member.
This output shows the syntax of the archive copy-sw
command:
3750_Stack#archive copy-sw ? /destination-system specify destination system to receive software /force-reload Unconditionally reload system after successful sw upgrade /leave-old-sw Leave old sw installed after successful sw upgrade /no-set-boot do not update BOOT setting on systems after installing sw /overwrite OK to overwrite an existing image /reload Reload system (if no unsaved config changes) after successful sw upgrade /safe Always load before deleting old version 1 copy software from system 1 2 copy software from system 2 3 copy software from system 3
For the /destination-system destination-stack-member-number , specify the number of the stack member to which the source that runs the image file needs to be copied. If you do not specify the stack member number, the running image file is copied to all stack members by default.
Specify /force-reload to unconditionally force a system reload after the successful download of the software image. If you do not want to use /force-reload , reset the updated stack member manually withreload slot switch_member_number to put this configuration change into effect.
For the source-stack-member-number , specify the number of the stack member from which to copy the running image file. The stack member number range is 1 to 9.
If you receive an oversubscribe syslog message during reload, then issue the archive copy-sw /overwrite /destination-system command to overwrite the software image in the Flash memory with the downloaded one.
This is an example of the archive copy-sw
command:
This archive copy-sw
command copies the current running Cisco IOS image from switch 1 to switch 3 on the 3750 switch stack.
archive copy-sw /overwrite /destination-system 3 1
Reload the switch member 3.
reload slot 3
Method 2 - .tar Image
You can use this method if you use the device manager to manage the switch stack. Extract the .tar image into the Flash file system of the newly added switch. It is assumed that you already have the .tar image on the switch. If it is not available, you can download Cisco Catalyst 3750 Software from page and copy to the switch with TFTP. theSoftware Download site.
