A message also appears when Auto Config completes. The user is reminded with a message indicating that configuration must be saved in order to avoid performing Auto Config on the next reboot. When Auto Config has successfully completed, an administrator can execute a show running-config command to validate the contents of configuration. Saving a Configuration An administrator 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 copy runningconfig startup-config command and should be done after validating the contents of saved configuration. Host-Specific Config File Not Found If the Auto Config process fails to download a configuration file, a message is logged. If a final configuration file is not downloaded, as described in Table 9-1, the Auto Config procedure continues to issue TFTP broadcast requests. The frequency of the broadcasts is once per 10 minute period. Terminating the Auto Config Process A user can terminate the Auto Config process at any time prior to the downloading of the config file. This is useful when the switch is disconnected from the network, or when the requisite configuration files are configured on TFTP servers. Termination of the Auto Config process ends further periodic requests for a host-specific file. Managing Downloaded Config Files The configuration files downloaded by Auto Config are stored in the nonvolatile memory. The files may be managed (viewed, displayed, deleted) along with files downloaded by the configuration scripting utility. 154 Utility
