You want to boot using an alternate IOS image. To specify which IOS image the router should load next time it reboots, use the boot system command:. The sequence of the boot system commands is extremely important, as the router will attempt to load the IOS images in the order that they appear in the configuration file.
The router can store as many IOS images in its flash memory as there is space to hold. If there is only one file, it can safely assume that this must be the IOS image to load. However, if the router has several images in its flash storage, you need to specify which one it should load, or the router will simply select one.
This is particularly true on routers that have additional flash memory in the form of PCMCIA cards, which can hold many files, not all of which are even necessarily IOS images. With the default configuration register settings, the router will attempt to load the first accessible IOS image it finds in its flash storage.
However, loading the first available image might not be appropriate. For instance, in our last recipe we showed that, if you have space, you can download a new IOS image without erasing old images. In this case, you probably want the router to load the newer IOS image. And it would be better still if the router would try the new image first, and revert to the old image if the first one failed to load correctly for any reason.
The boot system command allows you to specify not only which IOS images to boot from, but also the order to try them in if it has trouble booting. In the example, this router will try a succession of three different IOS images. If they all fail, it will resort to using its boot ROM image. As we noted earlier, the sequence of the boot system commands is important since the router will attempt to load the IOS images in order of entry.
This means that the only way to add a new IOS image to load is to remove all of the old boot system commands and reenter them again in the order of preference.
You can remove all of the boot system commands at once with the following command:. Once the old boot system commands have been removed, you can configure a new set in whatever order you require. Recipe 1. Table shows all of the different options for the boot system command. The last octet in the configuration register must be set to 2or the router will ignore the boot system commands completely.
For instance, if the last octet of the configuration register is set to 1the router will boot from ROM and ignore the boot system commands. The config-register command allows you to set the appropriate configuration register values:. It will survive a reload without being saved. In fact, the new setting will not take effect until after the next reload:. After setting the appropriate boot system commands and reloading the router, you can see which image file the router used to boot with the show version command:.
In this case, the router says that it loaded its IOS image from slot0:as configured. After changing your boot system commands, you should be sure to reboot and verify that it behaved as expected.The following example shows how to configure the controller IP address This example shows how to configure the dot1x username ABC and password pass You can remove the private-config by using the clear capwap private-config command.

The default enable password is Cisco. After joining the controller, the user can configure new settings on the LAP via the controller. When you move your AP to a different location in your network and the LAP cannot join the previous WLC, or if you want to manually reconfigure the AP to join another WLC, you have to enter the new controller information in order to allow your AP to associate with a different controller.
When the LAP is registered to the controller, you can use these commands from the controller in order to reset the configuration on the LAP:. In order to use that method you need to have physical access to AP. Skip to content Skip to footer. Available Languages. Download Options.

Cisco Prime Infrastructure simplifies the version management and routine deployment of software updates to your devices by helping you plan, schedule, download, and monitor software image updates. You can also view software image details, view recommended software images, and delete software images. The software image management page provides a consolidated view of the various aspects of image management such as software image management lifecycle widget, software image summary, and job details.
Prime Infrastructure stores all of the software images for the devices in your network. The images are stored according to the image type and version. Before you can upgrade software images, you must configure your devices with Telnet or SSH credentials.
Also SNMP read-write community strings that match the community strings entered when the device was added to Prime Infrastructure must be configured. SSH or Telnet must be configured for importing the images from a device. Prime Infrastructure can transfer files to and from devices only if the SNMP read-write community strings configured on your devices match the strings that were specified when the devices were added to Prime Infrastructure.
Otherwise, several Software Image Management operations will fail. Because collecting software images can slow the data collection process, by default, Prime Infrastructure does not collect and store device software images in the image repository when it performs inventory collection. Users with Administration privileges can change that setting using the following procedure.
To retrieve and store device images in the image repository when Prime Infrastructure performs inventory collection, check the Collect images along with inventory collection check box. Click Save.

The upgrade is performed in order to take advantage of the new features available in the new Cisco IOS image and to fix issues in the previous software version. It is usually performed as a part of regular maintenance task. In this section, you are presented with the information on how to upgrade the access point through the GUI. Complete these steps:.
Check the current software version of the AP. On the main page, click on the System Software menu from the left hand side. Leave the name as it was when you downloaded the file from cisco.
Click the Upgrade button. A status window similar to the one shown in Figure 2 appears. You can download a new image file and choose to replace the current image or keep the current image.
You can work with the access point from the other image in the flash. For image namespecify the Cisco IOS filename that you plan to use to upgrade the access point. As mentioned earlier, do not change the name of the Cisco IOS file. Leave it as the default. You find these logs during the successful file transfer:. If there is not enough space to install the new image and keep the current running image, the download process stops, and an error message is displayed.
On the TFTP server, check to see if you receive logs about this file transfer. Once the new image is downloaded, the access point automatically reloads. At this time, the connection to the access point is lost.
Login to the AP again. If you use the CLI, you can check this with the show version command. Make sure that the TFTP server is reachable from the access point. Disable any firewall to see if it blocks the TFTP port udp The root directory is also called the current directory of the TFTP server. Ensure that you download the appropriate image for a particular model of the access point. Otherwise the download algorithm on the AP rejects the image and displays an error.
Make sure that the access point meets the memory requirements specified for the image in the downloads page.
Deleting all the contents of a folder on a Cisco IOS device
If there is not sufficient space in the flash to hold the Cisco IOS file, it produces an error message. During the upgrade process, a status pop-up window appears. Make sure that the browser allows pop-up windows from the AP to appear.

The WLC, by default, maintains two images. These images are the primary image and the backup image.
The primary image is the active image used by the WLC while the backup image is used as a backup for the active image. The controller bootloader ppcboot stores a copy of the active primary image and the backup image.
If the primary image becomes corrupted, you can use the bootloader to boot with the backup image. You can change the active image using either of the following two methods: During boot process or manually changing the active boot image. Assuming that the controller has a valid backup image, reboot the controller. During the boot process on the controller, press Esc key to see additional options.
You are prompted to choose an option from the following:. ChooseOption 3: Change active boot image from the boot menu to set the backup image as the active boot image. The controller, when rebooted, boots with the new active image. Each controller can boot off the primary, previously loaded OS image or boot off the backup image, an OS image that was loaded earlier.
By default, the primary image on the controller is chosen as the active image. In order to remove or overwrite an image on the WLC, boot up the WLC with the image that you want to keep and perform an upgrade. This way, the new image replaces the primary image. On the controller CLI, use the show boot command to view the primary and backup image present on the controller. Skip to content Skip to footer. Available Languages.
