The predownload failure is only a one-time failure. If you upgrade from 8. After the controller is reloaded with 8. If an AP is in the process of downloading a software image, the status of the download is not shown on the controller CLI. During the image download process, any configuration performed on the AP via the controller CLI is not applied.

Therefore, we recommend that you do not perform any configuration on the AP via the controller CLI if an image download on the AP is in progress. In the AP Image Pre-download section, perform one of the following:. To instruct all the access points to predownload a primary image from the controller, click Download Primary under the AP Image Pre-download.

To instruct all the access points to swap their primary and backup images, click Interchange Image. To download an image from the controller and store it as a backup image, click Download Backup. To terminate the predownload operation, click Abort Predownload. Click OK. Click Apply. Specify APs that will receive the predownload image by entering one of these commands:. Specify APs for predownload by entering this command:. The primary image is the new image; the backup image is the existing image.

APs always boot with the primary image. Display detailed information on APs specified for predownload by entering this command:. The output lists APs that are specified for predownloading and provides for each AP, primary and secondary image versions, the version of the predownload image, the predownload retry time if necessary , and the number of predownload attempts. The output also includes the predownload status for each device. The status of the APs is as follows:.

Predownloading—The AP is predownloading the image. Not supported—The AP , , and does not support predownloading. Initiated—The AP is waiting to get the predownload image because the concurrent download limit has been reached. Failed—The AP has failed 64 predownload attempts. Set a reboot time for the controller and the APs. Use one of these commands to schedule a reboot of the controller and APs:.

Specify the amount of time delay before the devices reboot by entering this command:. The swap operand in the reset command will result in the swapping of the primary and backup images on both the controller and the AP and sets the default flag on the next controller reboot.

The controller sends a reset message to all joined APs, and then the controller resets. Specify a date and time for the devices to reboot by entering this command:. The controller sends the announcement trap the configured number of minutes before the reset. Cancel the scheduled reboot by entering this command:. Use the show reset command to display scheduled resets. The controller, by default, maintains two software images: a primary image and a backup image. The primary image is the active image used by the controller and the backup image is used as a backup for the primary active image.

The controller bootloader ppcboot stores a copy of the primary active image and the backup image. If the primary image is corrupted, you must use the bootloader to boot with the backup 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:. Choose Option 4: 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.

To change the controller boot option, use the config boot command. By default, the primary image on the controller is chosen as the active image. From the Image drop-down list, choose the image to be used as the active image. When you upgrade the controller with the new image, the controller automatically writes the new image as the primary image and the previously existing primary image is written over the backup image.

On the controller CLI, use the show boot command to view the primary and backup image present on the controller. Download the required recovery image from Cisco. Connect the TFTP server to the same subnet as the target access point and power-cycle the access point.

The access point boots from the TFTP image and then joins the controller to download the oversized access point image and complete the upgrade procedure. After the access point has been recovered, you can remove the TFTP server. Skip to content Skip to search Skip to footer. Book Contents Book Contents.

Caution Do not power down the controller or any access point during this process; otherwise, the software image could be corrupted. Upgrading a controller with a large number of access points can take as long as 30 minutes, depending on the size of your network. However, with the increased number of concurrent access point upgrades supported in the controller software release, the upgrade time should be significantly reduced.

The access points must remain powered, and the controller must not be reset during this time. Guidelines and Restrictions for Upgrading Controller Software The following are some of the general guidelines and restrictions that are applicable when upgrading the controller software. You can reduce the network downtime using the following options: You can predownload the AP image. Related Concepts Predownloading an Image to an Access Point Upgrading Controller Software GUI Before you begin Before upgrading the controller software, we recommend that you consult relevant release notes for any release-specific restrictions.

Procedure Step 1 Upload your controller configuration files to a server to back them up. Note We highly recommend that you back up your configuration files of the controller prior to upgrading the controller software. Otherwise, you must manually reconfigure the controller.

The software releases are labeled as follows to help you determine which release to download: Early Deployment ED —These software releases provide new features, new hardware platform support, and bug fixes. Step 3 Copy the controller software image filename. Note In Release 8. Step 4 Optional Disable the Note For busy networks, controllers on high utilization, or small controller platforms, we recommend that you disable the Step 6 From the File Type drop-down list, choose Code.

Step 9 Optional If you are using a TFTP server, the default values of 10 retries for the Maximum Retries text field, and 6 seconds for the Timeout text field should work correctly without any adjustment. Step 10 In the File Path field, enter the directory path of the software. Step 11 In the File Name field, enter the name of the controller software file filename.

Step 13 Click Download to download the software to the controller. Step 14 Optional After the download is complete, you can choose to predownload the image to your access points. Step 15 Click Reboot to reboot the controller.

Step 16 If prompted to save your changes, click Save and Reboot. Step 17 Click OK to confirm. Step 18 After the controller reboots, repeat step 6 to step 16 to install the remaining file. Step 19 If you have disabled the Note We highly recommend that you back up your controller's configuration files prior to upgrading the controller software.

Step 4 Log onto the controller CLI. Step 6 Optional Disable the Step 7 View current download settings by entering the transfer download start command. Optional If you are using a TFTP server, also enter these commands: transfer download tftpMaxRetries retries transfer download tftpPktTimeout timeout Note The default values of 10 retries and a 6-second timeout should work correctly without any adjustment. However, you can change these values.

To do so, enter the maximum number of times that the TFTP server attempts to download the software for the retries parameter and the amount of time in seconds that the TFTP server attempts to download the software for the timeout parameter. If you are using an FTP server, also enter these commands: transfer download username username transfer download password password Optional transfer download port port Note The default value for the port parameter is Step 9 View the current updated settings by entering the transfer download start command.

Step 10 Optional After the download is complete, you can choose to predownload the image to your access points. Step 11 Save the code update to nonvolatile NVRAM and reboot the controller by entering this command: reset system The controller completes the bootup process. Step 12 After the controller reboots, repeat Steps 7 through 11 to install the remaining file. Step 13 If you have disabled the Cisco AP has 32 MB of total flash memory and can support the predownload feature.

The following sequence of actions occur: During boot time, the access point sends a join request. Note Normally, when upgrading the image of an AP, you can use the preimage download feature to reduce the amount of time the AP is unavailable to serve clients. At the time of the reset, if any AP is downloading the controller image, the scheduled reset is canceled.

Predownloading an Image to Access Points—Global Configuration GUI To predownload an image to the APs, you must perform the following steps after upgrading your controller software image and before you reboot the controller for the new image to take effect. Step 3 Click OK. Step 4 Click Apply. Complete—The AP has completed predownloading. Step 2 Set a reboot time for the controller and the APs.

Note The swap operand in the reset command will result in the swapping of the primary and backup images on both the controller and the AP. Optional Set up an SNMP trap message that announces the upcoming reset by entering this command: reset system notify-time minutes The controller sends the announcement trap the configured number of minutes before the reset. Cancel the scheduled reboot by entering this command: reset system cancel Note If you configure reset times and then use the config time command to change the system time on the controller, the controller notifies you that any scheduled reset times will be canceled and must be reconfigured after you set the system time.

Information similar to the following appears: System reset is scheduled for Apr 08 Current local time and date is Apr 07 A trap will be generated 10 minutes before each scheduled system reset. Use 'reset system cancel' to cancel the reset. Configuration will be saved before the system reset. You can change the active image using either of the following two methods: Assuming that the controller has a valid backup image, reboot the controller.

You are prompted to choose an option from the following: Run primary image Run backup image Manually upgrade primary image Change active boot image Clear configuration Choose Option 4: Change active boot image from the boot menu to set the backup image as the active boot image. Note To properly use the bootloader menu, you must have a console connection. Step 2 From the Image drop-down list, choose the image to be used as the active image. Step 3 Save the configuration and reboot the controller.

The controller, when rebooted, boots with the image that you chose. Note The previously existing backup image will be lost. The best way to avoid the need for AP recovery is to prevent an AP from power-cycling during a system upgrade. Note IPv6 is not supported in AP recovery images. Procedure Step 1 Download the required recovery image from Cisco.

Step 2 Connect the TFTP server to the same subnet as the target access point and power-cycle the access point. Was this Document Helpful? Yes No Feedback. Resolution : Perform client troubleshooting in Cisco Prime Infrastructure to determine if the problem is related to the OfficeExtend access point or the client. The access point is not broadcasting the enterprise WLAN. Resolution : Ask the teleworker to check the cables, power supply, and LED status. If you still cannot identify the problem, ask the teleworker to try the following:.

If the PC cannot connect to the Internet, check the router or modem. If the PC can connect to the Internet, check the home router configuration to see if a firewall or MAC-based filter is enabled that is blocking the access point from reaching the Internet. Log on to the home router and check to see if the access point has obtained an IP address. The access point cannot join the controller, and you cannot identify the problem. Resolution : A problem could exist with the home router.

Ask the teleworker to check the router manual and try the following:. It prevents outside users from getting direct access to a server that has company data. The teleworker experiences problems while configuring a personal SSID on the access point. The home network needs to be rebooted. Resolution : Ask the teleworker to follow these steps:. Leave all devices networked and connected, and then power down all the devices. Turn on the cable or DSL modem, and then wait for 2 minutes.

Check the LED status. Turn on the home router, and then wait for 2 minutes. Turn on the access point, and then wait for 5 minutes. A link test is used to determine the quality of the radio link between two devices. Two types of link-test packets are transmitted during a link test: request and response. Any radio receiving a link-test request packet fills in the appropriate text boxes and echoes the packet back to the sender with the response type set.

The radio link quality in the client-to-access point direction can differ from that in the access point-to-client direction due to the asymmetrical distribution of the transmit power and receive sensitivity on both sides. Two types of link tests can be performed: a ping test and a CCX link test. With the ping link test , the controller can test link quality only in the client-to-access point direction.

The RF parameters of the ping reply packets received by the access point are polled by the controller to determine the client-to-access point link quality. With the CCX link test , the controller can also test the link quality in the access point-to-client direction.

The controller issues link-test requests to the client, and the client records the RF parameters received signal strength indicator [RSSI], signal-to-noise ratio [SNR], and so on. Both the link-test requestor and responder roles are implemented on the access point and controller. Not only can the access point or controller initiate a link test to a CCX v4 or v5 client, but a CCX v4 or v5 client can initiate a link test to the access point or controller. The controller shows these link-quality metrics for CCX link tests in both directions out— access point to client; in— client to access point :.

Signal strength in the form of RSSI minimum, maximum, and average. Signal quality in the form of SNR minimum, maximum, and average. Data rate of a successfully transmitted packet. The controller shows this metric regardless of direction:.

The controller software supports CCX versions 1 through 5. The controller stores the CCX version of the client in its client database and uses it to limit the features for this client. If a client does not support CCXv4 or v5, the controller performs a ping link test on the client.

If a client times out during a CCX link test, the controller switches to the ping link test automatically. Hover your cursor over the blue drop-down arrow for the desired client and choose LinkTest. A link test page appears. This page shows the results of the CCX link test.

The Link Test results of CCX clients when it fails will default to ping test results if the client is reachable. Click OK to exit the link test page. Use these commands to run a link test using the controller CLI:. When CCX v4 or later releases is enabled on both the controller and the client being tested, information similar to the following appears:. When CCX v4 or later releases is not enabled on either the controller or the client being tested, fewer details appear:.

Adjust the link-test parameters that are applicable to both the CCX link test and the ping test by entering these commands from configuration mode:. Skip to content Skip to search Skip to footer.

AP33 Country code Domain allowed by Country Name Server Telnet State Enabled Ssh State Understanding How Converted Access Points Send Crash Information to the Controller When a converted access point unexpectedly reboots, the access point stores a crash file on its local flash memory at the time of the crash.

Understanding How Converted Access Points Send Radio Core Dumps to the Controller When a radio module in a converted access point generates a core dump, the access point stores the core dump file of the radio on its local flash memory at the time of the radio crash. The size should be greater than zero if a core dump file is available. Step 5 In the File Path text box, enter the directory path of the file.

Step 6 In the File Name text box, enter the name of the radio core dump file. Note The filename that you enter should match the filename generated on the controller. Step 8 Click Upload to upload the radio core dump file from the controller. Step 2 If you are using an FTP server, also enter these commands: transfer upload username username transfer upload password password transfer upload port port Note The default value for the port parameter is Step 3 View the updated settings by entering this command: transfer upload start Step 4 When prompted to confirm the current settings and start the software upload, answer y.

Uploading Memory Core Dumps from Converted Access Points By default, access points converted to lightweight mode do not send memory core dumps to the controller. Step 4 In the File Name text box, enter a name of the access point core dump file such as dump.

Step 5 Select the File Compression check box to compress the access point core dump file. Step 6 Click Apply to commit your changes. Step 7 Click Save Configuration to save your changes. Note When you choose compress , the file is saved with a.

Step 2 Enter the save config command to save your changes. Disabling the Reset Button on Access Points Converted to Lightweight Mode You can disable the reset button on access points converted to lightweight mode. Note The driver debugs are not enabled on the WLC. If you have access to the AP console, the driver debugs can be enabled.

These commands are applicable for debugging the client AP console when it is accessible. AP configuration is not saved across reboots. Troubleshooting OfficeExtend Access Points This section provides troubleshooting information if you experience any problems with your OfficeExtend access points. Figure 1. OfficeExtend Access Point Radiation Patterns Troubleshooting Common Problems Most of the problems experienced with OfficeExtend access points are one of the following: The access point cannot join the controller because of network or firewall issues.

Resolution : Ask the teleworker to follow these steps: Leave all devices networked and connected, and then power down all the devices. Turn on the client. Link Test A link test is used to determine the quality of the radio link between two devices. Step 2 Hover your cursor over the blue drop-down arrow for the desired client and choose LinkTest.
