Restrictions for Cisco IOS Resilient Configuration
•This feature is available only on platforms that support a Personal Computer Memory Card
International Association (PCMCIA) Advanced Technology Attachment (ATA) disk. There must be
enough space on the storage device to accommodate at least one Cisco IOS image (two for
upgrades) and a copy of the running configuration. IOS Files System (IFS) support for secure file
systems is also needed by the software.
•It may be possible to force removal of secured files using an older version of Cisco IOS software
that does not contain file system support for hidden files.
•This feature can be disabled only by using a console connection to the router. With the exception
of the upgrade scenario, feature activation does not require console access.
•You cannot secure a bootset with an image loaded from the network. The running image must be
loaded from persistent storage to be secured as primary.
•Secured files will not appear on the output of a dir command issued from an executive shell
because the IFS prevents secure files in a directory from being listed. ROM monitor (ROMMON)
mode does not have any such restriction and can be used to list and boot secured files. The
running image and running configuration archives will not be visible in the Cisco IOS dir command
output. Instead, use the show secure bootset command to verify archive existence.
