Once a hostname has been determined, the switch then issues a TFTP request for a file named ".cfg" file, where is the first 32 characters of the switch's hostname. If the switch is unable to map its IP address to a hostname, Auto Config sends TFTP requests for the default configuration file "host.cfg." Table 9-1 summarizes the config files which may be downloaded, and the order in which they are sought. Table 9-1.

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. 164 Utility
