Defragmenting the Flash File System

The flash memory is defragmented automatically whenever there is not enough memory available for a binary
upgrade. However, fragmentation can occur whenever a new file is uploaded to the unit. Fragmentation causes
sectors of available memory to become separated by ones allocated to files. In some cases, the total available
memory might be sufficient for a binary upgrade, but that memory may not be available in one contiguous region.
To defragment the flash memory, do the following:
1. Log in to the device as an admin user and access the CLI shell. For more information about accessing the
CLI shell, refer to
2. Defragment the flash memory by typing:
