You can point to the source image on your TFTP server or in flash if you have it copied to flash. Note Old files listed in the logs should be removed using the request platform software package clean switch all command, after reload. If not, you can manually boot flash:packages. Note When you boot the new image, it will automatically update the boot loader.
Step 6 When the new image boots up, you can verify the version of the new image, by checking show version. Step 7 After you have successfully installed the image, you no longer need the. Note If you have a stack, you must copy the image to the flash of each switch in your stack. Step 4 Clear the boot variable. Step 5 Edit the boot variable to point to the new image. Step 6 Use the write memory command to save the configuration change. Step 7 Use the show boot command to confirm that your boot variable is pointing to the new image.
Step 8 Reload the switch. Step 9 If your switches are configured with auto boot, the stack will automatically boot up with the new image. Step 10 When the new image boots up, you can verify the version of the new image, by checking show version. Step 11 Ensure you have enough space in flash to expand a new image by cleaning up old installation files.
Note Use the switch all option to clean up all switches in your stack. Step 12 Copy the image from your tftp server to flash. Step 13 Use the request platform software package expand switch all file flash:image.
Note Use the switch all option to upgrade all switches in your stack Use the auto-copy option to copy the. Step 14 Clear the boot variable. Step 15 Edit the boot variable to point to the new image. Step 16 Use the write memory command to save the configuration change. Step 17 Use the show boot command to confirm that your boot variable is pointing to the new image. Step 18 Reload the switch. Step 19 If your switches are configured with auto boot, the stack will automatically boot up with the new image.
Step 20 When the new image boots up, you can verify the version of the new image, by checking show version. Step 1 Ensure you have enough space in flash to expand a new image by cleaning up old installation files.
Use the switch all option to clean up all switches in your stack. Step 2 Copy the new image to flash: or skip this step if you want to use the new image from your TFTP server. Step 4 Use the boot system flash:packages. Use the write memory command to save boot settings. Step 5 Use the request platform software package install switch all file flash: new auto-copy command to install the target image to flash.
We recommend copying the image to a TFTP server or the flash drive of the active switch. If you point to an image on the flash or USB drive of a member switch instead of the active , you must specify the exact flash or USB drive - otherwise installation fails. For example, if the image is on the flash drive of member switch There are packaging changes in the different Use the auto-copy option to copy the. Note When you execute the command, the following message is displayed: Unknown package type 21 This is expected and does not affect the upgrade.
See CSCux Note Old files listed in the logs will not be removed from flash. Step 6 After you have successfully installed the software, verify that the flash partition has five new. See sample output below:. If you copied the file to flash. If an image is still saved, you can delete it, if not, it has been deleted as part of the install operation and you can skip this step. Step 9 If the switch is configured with auto boot, then the stack automatically boots up with the new image.
Step 10 When the new image boots up, you can verify the version of the new image, by using the show version command:. Sample output in the example is of an upgrade scenario; the same steps apply when you downgrade as well.
Step 5 Use the request platform software package install switch all file flash: auto-copy command to install the target image to flash. Step 6 After the software has been successfully installed, verify that the flash partition has five new. See sample output below.
Step 7 Reload the switch. Step 8 If your switches are configured with auto boot, then the stack will automatically boot up with the new image. Step 9 When the new image boots up, you can verify the version of the new image, using the show version command.
Step 4 Use the request platform software package install command with the new option to downgrade your stack. You can point to the source image on your tftpserver or in flash if you have it copied to flash.
Use the switch all option is needed to upgrade all switches in your stack. Note The old files listed in the logs should be removed using the software clean command, after reload. Step 5 After you have successfully installed the image, you no longer need the. Step 6 Reload the switch. Step 7 If your switches are configured with auto boot, then the stack will automatically boot up with the new image. It will remain updated. Step 13 Use the software expand command to expand the target image to flash and move from bundle mode to install mode.
Step 21 After you have successfully installed the image, you no longer need the. This command provides options to activate or deactivate any license supported on the platform. Activate IP Services license. Enter the switch ID. Enter acceptEULA to indicate acceptance. Check the reboot license level is ipservices eval. Activate IP Base license on all the switches in the stack. Check the reboot license level is ipbase for all the switches.
If the license mismatch switch has a lower license level than other switches in the stack, and the stack is running at IP Services and the mismatch switch is booted with IP Base license. Check the license level of the license mismatch switch. Activate IP Services license on all the mismatch switches in the stack. Reboot the license mismatch switch to boot with ipservices and join the stack.
If the license mismatch switch has a higher license level than other switches in the stack, and the stack is running at IP Base and the mismatch switch is booted with IP Services license. Activate IP Base license on the license mismatch switch. Reboots the license mismatch switch to boot with ipbase and join the stack. The Cisco Catalyst Series Switches supports three different feature sets:. For more information about the features, see the product data sheet at this URL:.
Caveats describe unexpected behavior in Cisco IOS releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved. The Bug Search Tool BST allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version.
The BST is designed to improve the effectiveness in network risk management and device troubleshooting. I think the configuration is identical on 16 and 3 releases. What do you have configured, can you post that? It is and 3. Do we have an estimated date the 3. X IOS will end its life? Fantastic response, Austin. Buy or Renew. Find A Community. Cisco Community.
