Canceling a Distribution
To cancel software distribution at any time, you must click Cancel All. This cancels distribution to
APs that have not yet been upgraded, restarts services that were shut down during the upgrade, and
removes the image file from the AP RAM. Cancellation is performed serially for multiple AP
distributions. Canceling during distribution does not damage the APs. If the distribution on a
remote AP is cancelled, the AP will be automatically rebooted. You can cancel distribution to an
individual AP at any time except when the status is Updating Flash … Error, or Done (Rebooting).
If you leave the Software Upgrade panel before the distribution is complete without clicking the
Cancel All, software distribution continues in the background, but it is not possible to return to the
Distribution Status page.
Download Status
During distribution, the Download State column displays the current status of the distribution
process (see Figure 187).
Status information is automatically updated every 10 seconds. The status information shows clearly
the stage of the distribution process and identifies any problems. Table 17 lists the possible status
values and their meaning.
Status Explanation
Not scheduled This AP has not been scheduled to receive a software update.
Scheduled The update has been ordered for this AP, but has not yet begun.
Canceling A request has been made to cancel the distribution; however, the request is not
complete. For example, this message is displayed if a request has been made
to cancel distribution to an AP waiting its turn in the distribution list.
Canceled Distribution to the AP is canceled.
AP Unreachable The enrolled AP is not reachable for distribution.
Retrying 1, Retrying 2 If communication with the AP is lost during distribution, the process waits for
two minutes and then retries the distribution. Three retries are attempted
before the process stops and an error message is presented. Retrying 1 and
Retrying 2 status represent the first and second retries. Retries may occur, for
example, during upgrade of backhaul APs, if the radio signal is temporarily
lost and retrunking is required.
There is a timeout of two minutes between retries. With a total of three retries,
it can take up to 10 minutes before a distribution on an AP is deemed to be in
error.
The message changes to In Progress .. (XX %) when the retry actually starts.
In Progress .. (XX %) Upgrade is underway on the AP and is XX% complete.
Error All retries have finished and the AP could not be upgraded due to some
internal error.
Unknown An unknown error has occurred.
Image Integrity Error The image has passed the compatibility test but failed the integrity check after
the distribution, but before the flash update.
Updating Flashing ... Image distribution is complete and it is being saved onto the AP's persistent
storage.
