Auto Image and Configuration Update

When the switch boots and triggers an Auto Configuration, a message 

displays on the console screen to indicate that the process is starting. After 

the process completes, the Auto Configuration process writes a log message. 

When Auto Configuration has successfully completed, you can execute a 

show running-config command to validate the contents of configuration.

The Auto Configuration feature includes an AutoSave capability that allows 

the downloaded configuration to be automatically saved; however, AutoSave 

is disabled by default. If AutoSave has not been enabled, you must explicitly 

save the downloaded configuration in nonvolatile memory on the stack 

master. This makes the configuration available for the next reboot. In the 

CLI, this is performed by issuing a write command or copy running-config 

startup-config command and should be done after validating the contents of 

saved configuration.

You can terminate the Auto Configuration process at any time before the 

image or configuration file is downloaded. This is useful when the switch is 

disconnected from the network. Termination of the Auto Configuration 

process ends further periodic requests for a host-specific file.
The Auto Configuration process automatically starts after a reboot if the 

configuration file is not found on the switch. The configuration file will not 

be found if it has never been saved on the switch, or if you issue a command 

to erase the configuration file (clear config or erase startup-config).

The configuration files downloaded by Auto Configuration are stored in the 

nonvolatile memory as .scr files. The files may be managed (viewed or 

deleted) along with files downloaded by the configuration scripting utility.
A file is not automatically deleted after it is downloaded. The file does not 

take effect upon a reboot unless you explicitly save the configuration (the 

saved configuration takes effect upon reboot). If you do not save the 

configuration downloaded by the Auto Configuration feature, the Auto 

Configuration process occurs again on a subsequent reboot. This may result 

in one of the previously downloaded files being overwritten.
