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. What Are the Dependencies for DHCP Auto Configuration? The Auto Configuration process from TFTP servers depends upon the following network services: • A DHCP server must be configured on the network with appropriate services. • An image file and a text file containing the image file name for the switch must be available from a TFTP server if DHCP image download is desired. • A configuration file (either from bootfile (or) option 67 option) for the switch must be available from a TFTP server. • The switch must be connected to the network and have a Layer 3 interface that is in an UP state. • A DNS server must contain an IP address to hostname mapping for the TFTP server if the DHCP server response identifies the TFTP server by name. 384 Auto Image and Configuration Update
