Introduction

This document describes the steps to upgrade the software image on Cisco Catalyst 3750 series switches with the command-line interface (CLI).

Prerequisites

Requirements

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:

- Finding the Software Version and Feature Set

- Deciding Which Files to Use

- Upgrading a Switch by Using the Device Manager or Network Assistant

- Upgrading a Switch by Using the CLI

- Recovering from a Software Failure

Components Used

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.

Conventions

Refer to the Cisco Technical Tips Conventions for more information on document conventions.

Find the Software Version and Feature Set

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.

Find the Priority Value of a Catalyst 3750 Switch

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.

*2       primary    000d.bd5c.1680     15        Ready

Decide Which Files to Use

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 and Memory Requirements

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:

- 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:

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.

3750 Series Switch Stack Cisco IOS Upgrade - Automatic (.tar Image)

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.

Step-by-Step Instructions

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 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:

New software image installed in flash:c3750-i5-mz.122-20.SE

All software images installed.

!--- Installation of the image and supporting files is now complete

!--- 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, run 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, run the dir flash: and the dir flash 1: commands. 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.

Run 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.

3750 Series Switch Stack Cisco IOS Upgrade - Manual (.tar Image)

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:

1. Copy the .tar image from the TFTP server to the primary switch.

2. Extract the .tar image into all the Flash file systems of the switches.

3. 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-by-Step Instructions

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.

3750-stack#copy tftp: flash:

Address or name of remote host []? 10.10.10.10

Source filename []? c3750-advipservicesk9-tar.122-25.SEE1.tar

Destination filename [c3750-advipservicesk9-tar.122-25.SEE1.tar]?

Accessing tftp://10.10.10.10/c3750-advipservicesk9-tar.122-25.SEE1.tar...

Loading c3750-advipservicesk9-tar.122-25.SEE1.tar from 10.10.10.10 (via Vlan10):

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

!--- 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:

1. 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/print.gif (625 bytes)

!--- Output is suppressed.

2. Extract the .tar file into the Flash on switch2.

3750-stack#archive tar /xtract c3750-advipservicesk9-tar.122-25.SEE1.tar flash2:

extracting c3750-advipservicesk9-mz.122-25.SEE1/html/images/print.gif (625 bytes)

!--- Output is suppressed.

3. 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/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 Series Switch Stack Cisco IOS Upgrade - Manual (.bin Image)

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 archive download-sw and archive upload-sw commands 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

Switch#  Role      Mac Address     Priority     State

--------------------------------------------------------

1       Member    0015.63f6.b700     5         Ready

*2       primary    0015.c6c1.3000     10        Ready

Step-by-Step Instructions

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:

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:

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

Image Transfer from TFTP Server Fails or Corrupted Cisco IOS image

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 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:

1. Upload the .bin file to the switch through the Xmodem.

2. Set the boot path to the correct file name.

3. Reload the switch.

4. 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

%Error Opening flash:update/info ("No such file or directory")

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:

1. Make sure you are able to ping the TFTP server IP address from the switch.

2. Verify your TFTP server works and if possible, try a different TFTP server.

3. Remove if you have any old information directory from the Flash.

4. 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.

Switches in the Stack do not Boot the New Image ("Version Mismatch")

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.

3       Member    000f.f794.3d00     5         Version Mismatch

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

- Method 2

- Method 3

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:

1. 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

2. 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.

ERROR: Image is not a valid Cisco IOS image archive.

The reason for this error message is that the archive command is for the .tar files and cannot be used with .bin files. In order to upgrade with the .bin file, use the copy command.

Upgrade Cisco IOS Software with Different Feature Sets

The Cisco Catalyst 3750 Series, by default, allows changes in feature sets while you upgrade to a later Cisco IOS release.

Error: The image in the archive which would be used to upgrade

Error: system number [dec] does not support the same feature set.

In order to overcome this issue, make use of the flag allow-feature-upgrade   while you execute the archive-download-sw command.

archive-download-sw /allow-feature-upgrade

This option is supported only from Cisco IOS release 12.2(35) SE or later.
