Maintaining System Images and Configuration Files
For detailed instructions on performing these tasks, refer to the Configuration Fundamentals
Configuration Guide.
Modifying, Downloading, and Maintaining Configuration Files
The following are frequently performed tasks to maintain configuration files:
•Copy configuration files from the ATM switch router to a network server—You can copy files to a
TFTP server or rcp server for backup purposes or to store a lternative configurations.
•Copy configuration files from a network server to the ATM switch router—You can copy
configuration files from a TFTP server or an rcp server to the running configuration or startup
configuration of the ATM switch router to restore a configuration, to use a configuration from
another device, or to ensure that you have the same configuration on several devices.
•Maintain configuration files larger than NVRAM—You can maintain configuration files larger than
NVRAM by compressing them, storing them on Flash memory devices, or storing them on TFTP or
rcp servers for downloading at system startup.
•Copy configuration files between different locations—You can copy configuration files from Flash
memory to the startup or running configuration, copy configuration files between Flash memory
devices, or copy a configuration file from a server to Flash memory.
•Reexecute the configuration commands in startup configuration or clear the configuration
information.
Modifying, Downloading, and Maintaining System Images
The following are frequently performed tasks to maintain system image files:
•Copy images from Flash memory to a network server—You can store system images for backup or
other purposes by copying them from a Flash memory device to a TFTP or rcp server.
•Copy images from a network server to Flash memory—You perform this procedure when upgrading
your system image or functional image.
•Copy images between local Flash memory devices.
Rebooting and Specifying Startup Information
The following commonly performed tasks are used to reboot the ATM switch router and specify startup
information:
•Modify the configuration register boot field—You use the configuration register boot field to specify
whether the ATM switch router loads a system image, and where it obtains the system image, or
whether the system image loads fro m ROM.
•Specify the system startup image—You can enter multiple boot commands in the startup
configuration file or in the BOOT environment variable to provide main and alternative methods for
loading a system image onto the ATM switch router.
•Specify the startup configuration file—You can configure the CONFIG_FILE environment variable
to load the startup configuration file from NVRAM (the default), from a Flash memory device, or
from a network server.
