Using WLANPoller will make the process faster, he added.
Enderle said that if an admin finds an AP whose flash memory is already too full to upgrade, a reboot sometimes clears temporary buffers or allows a small window for a manual transfer. However, with this specific log bug, a reboot may not be enough if the file is persistent. Admins should contact Cisco for the emergency cleanup script before attempting a mass push, he said.
Ultimately, Enderle said, the pushing of a flawed update is a supply chain integrity issue. CSOs should ask their teams, ‘Do we have monitoring in place for hardware health metrics (CPU, RAM, Flash), or only for ‘Up/Down’ status?’ An AP that is Up but has 0MB of free flash memory is a liability, he said.
