User Manual

•
Software: The system software image, which is saved in one of two flash sectors
called images (image1 and image2). The active image stores the active copy,
while the other image stores a second copy. The device boots and runs from the
active image. If the active image is corrupted, the system automatically boots from
the nonactive image. This is a safety feature for faults occurring during the boot
upgrade process. This is the default setting.
•
Text Configuration: A text-based configuration file enables you to edit a
configured text file (startup-config) offline as needed. The most common
usage of text-based configuration is to upload a working configuration from a
device, edit it offline to personalize it for another similar device (for example,
change the device name or IP address), and download it to that device.
