Auto Configuration Example A network administrator is deploying three PowerConnect switches and wants to quickly and automatically install the latest image and a common configuration file that configures basic settings such as VLAN creation and membership, RADIUS server settings, and 802.1X information. The configuration file also contains the command boot host autosave so that the downloaded configuration is automatically saved to the startup config. Enabling DHCP Auto Configuration and Auto Image Download If no configuration file is found during the boot process, the Auto Configuration feature uses the DHCP Auto Configuration process to download the configuration file to the switch. This example describes the procedures to complete the configuration. To use DHCP auto configuration: 1 Create a default config file for the switches named host.cfg. For information about creating configuration files, see Managing Images and Files. 2 Upload the host.cfg file to the TFTP server. 3 Upload the image file to the TFTP server. 4 Configure an address pool on the DHCP server that contains the following information: a The IP address (yiaddr) and subnet mask (option 1) to be assigned to the interface b The IP address of a default gateway (option 3) c DNS server address (option 6) d Name of config file for each host e Identification of the TFTP server by hostname (DHCP option 66 or the sname field in the DHCP header) or IP address (DHCP option 150 or the siaddr field in the DHCP header) f Name of the text file (option 125, the V-I vendor-specific Information option) that contains the path to the image file.
