9 - Additional Access Point Features

FD
Purpose: Displays the flash file system directory,
which includes information about the boot
file. Use this command to ensure that the
correct version of the file is in the active
boot segment.
Syntax: FD
Example:
To show only the files loaded in the active boot segment., enter:
FD ab:
Note
If the active segment contains no files when you reboot the access
point, the access point enters the AP monitor and you will no
longer be able to telnet to it during this session. If this occurs, you
must access the access point through its serial port to correct the
problem.
FDEL
Purpose: Deletes a particular file from a segment.
Note
When you use the FDEL command, the file is marked as invalid and
remains in the file system. To reclaim the file space, you must erase
the entire segment. Use the FE command to erase a segment.
Syntax: FDEL f
where f is the name of the file to be deleted.
Example:
To delete the file UAP.PRG from the inactive boot segment, enter:
FDEL IB:UAP.PRG
