PIX.
Q. What are the pre-requisites for using the device as remote stage?
A. It must be an IOS device and it must be running >= 12.0 version and it must support
CISCO-FLASH-MIB completely.
Q. What Configuration changes are performed by Software Management on the remote stage device?
A. tftp-server flash-partiiton-name:image-name alias image-name is the only command that will be
added to the Remote stage device to make the image copied to Remote Stage device as accessible
through TFTP from other devices.
Q. If I use the device as remote stage device does it impact the device's other functionalities? or what
are the performance implications of using the device as remote stage device?
A. There will not be any impact on device's other functionalities and also they will no be any
performance implications on the device that is used as Remote-Stage.

Q. What is the difference between Run-from-RAM and Run-from-Flash devices?
A. Most Cisco IOS devices load the software image from Flash to RAM when rebooting, then run the
software from RAM. Such devices are called Run-from-RAM (RFR) devices. For these devices, the
software image on Flash can be upgraded without rebooting the device.
Certain Cisco IOS devices (namely 2500s, 1600s, and AS5200s) run the system software image
directly from Flash. These are Run-from-Flash (RFF) devices. The Flash partition in which the
current image is stored is the RFF partition, which is read-only.
Software Management supports upgrading software images on RFF partitions by using a procedure
called Rxboot upgrade. Before upgrading, reboot the device and put it into Rxboot mode, which
makes the RFF partition available to write a new software image.
Q. When does Software Management use the remote copy protocol (rcp) to transfer images?
