Monitoring and Completing the DHCP Auto Configuration Process 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. Saving a Configuration The Auto Configuration feature includes an AutoSave feature 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 non-volatile memory. 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. Stopping and Restarting the Auto Configuration Process 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). Managing Downloaded Config Files 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. 392 Auto Image and Configuration Update
