Upgrading the Switch Software
These are the procedures for downloading software. Before downloading software, read this section for important information:
•
•
•
•
•
Finding the Software Version and Feature Set
The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. A subdirectory contains the files needed for web management. The image is stored on the system board flash device (flash:).
You can use the show version privileged EXEC command to see the software version that is running on your switch. The second line of the display shows the version.
Note
You can also use the dir filesystem: privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.
Deciding Which Files to Use
The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file. This file contains the Cisco IOS image file and the files needed for the embedded device manager. You must use the combined tar file to upgrade the switch through the device manager. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.
For the Catalyst 3750 and 3560 switches, Cisco IOS Release 12.2(25)SEA and earlier referred to the image that provides Layer 2+ features and basic Layer 3 routing as the standard multilayer image (SMI). The image that provides full Layer 3 routing and advanced services was referred to as the enhanced multilayer image (EMI).
Cisco IOS Release 12.2(25)SEB and later refers to the SMI as the IP base image and the EMI as the IP services image.
Table 4 lists the different file-naming conventions before and after Cisco IOS Release 12.2(25)SEB.

Catalyst 3750G Integrated Wireless LAN Controller Switch Software Compatibility
The Catalyst 3750 Integrated Wireless LAN Controller Switch is an integrated Catalyst 3750 switch and Cisco 4400 series wireless LAN controller that supports up to 25 or 50 lightweight access points. The switch and the internal controller run separate software versions, which must be upgraded separately.
To use the controller in the Catalyst 3750G Wireless LAN Controller Switch, the switch must be running one of these Cisco IOS software releases:
•
•
•
•
•
Note
If the switch image version is not compatible, the wireless LAN controller switch could stop functioning.
For information about the controller software, see the release notes on this page for Cisco Software Release 4.0.x.0 or later:
http://www.cisco.com/en/US/products/ps6366/prod_release_notes_list.html
For controller software upgrade procedure, see the Cisco Wireless LAN Controller Configuration Guide on this page:
.http://www.cisco.com/en/US/products/ps6366/products_installation_and_configuration_guides_list.html
Archiving Software Images
Before upgrading your switch software, make sure that you have archived copies of the current Cisco IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and until you have verified that the new Cisco IOS image works properly in your network.
Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for more information:
http://www.cisco.com/en/US/products/sw/iosswrel/ps5187/prod_bulletin0900aecd80281c0e.html
You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a host by using the copy flash: tftp: privileged EXEC command.
Note
You can also configure the switch as a TFTP server to copy files from one switch to another without using an external TFTP server by using the tftp-server global configuration command. For more information about the tftp-server command, see the "Basic File Transfer Services Commands" section of the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 at this URL:
Upgrading a Switch by Using the Device Manager or Network Assistant

Caution
Step 3
For more information, see Appendix B in the software configuration guide for this release.
Step 4
Step 5
Switch# ping tftp-server-addressFor more information about assigning an IP address and default gateway to the switch, see the software configuration guide for this release.
Step 6
Switch# archive download-sw /overwrite /reload tftp:[[//location]/directory]/image-name.tarThe /overwrite option overwrites the software image in flash memory with the downloaded one.
The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.
For //location, specify the IP address of the TFTP server.
For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive.
This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite the image on the switch:
Switch# archive download-sw /overwrite tftp://198.30.20.19/c3750-ipservices-tar.122-46.SE.tarYou can also download the image file from the TFTP server to the switch and keep the current image by replacing the /overwrite option with the /leave-old-sw option.
