There are two options to load patch to device - either through adopting controller (virtual controller) or device itself.
Both required EXEC (enable) mode to be accessible.To load patch through controller:
Load the kernel patch to controller's memory (example for AP7522)
device-upgrade load-image ap7522 ftp://<user>:<passwd>@<hostname|IP>[:port]/path/file/xx.patch
Confirm image was loaded correctly:
Execute below command on the controller to provide APs with the patch.
device-upgrade all force no-reboot
Confirm patch is loaded and change the boot to other partition on the AP’s using boot command on each AP
boot system primary/secondary
Reload APs from the controller using reload <hostname>
or reload on <RF-Domain>To load patch to AP itself:
Load the kernel patch to AP's memory (example for AP7522)
If AP does not auto-reload
confirm the patch was installed successfully and if necessary, change bootable partition
