DES-3028P:4#
enable autoconfig
Purpose
Used to activate the auto configuration function for the Switch. This will load a
previously saved configuration file for current use.
Syntax
enable autoconfig
Description
When autoconfig is enabled on the Switch, the DHCP reply will contain a
configuration file and path name. It will then request the file from the TFTP server
specified in the reply. When autoconfig is enabled, the ipif settings will
automatically become DHCP client.
Parameters None.
Restrictions
When autoconfig is enabled, the Switch becomes a DHCP client automatically
(same as:
config ipif System dhcp
). The DHCP server must have the TFTP
server IP address and configuration file name, and be configured to deliver this
information in the data field of the DHCP reply packet. The TFTP server must be
running and have the requested configuration file in its base directory when the
request is received from the Switch. Consult the DHCP server and TFTP server
software instructions for information on loading a configuration file.
If the Switch is unable to complete the auto configuration process the previously
saved local configuration file present in Switch memory will be loaded.
Example usage:
To enable auto configuration on the Switch:
DES-3028P:4#enable autoconfig
Command: enable autoconfig
Success.
DES-3028P:4#
When autoconfig is enabled and the Switch is rebooted, the normal login screen will appear for a few moments while the
autoconfig request (i.e. download configuration) is initiated. The console will then display the configuration parameters as they
are loaded from the configuration file specified in the DHCP or TFTP server. This is exactly the same as using a
download
configuration
command. After the entire Switch configuration is loaded, the Switch will automatically “logout” the server. The
configuration settings will be saved automatically and become the active configuration.
Upon booting up the autoconfig process is initiated, the console screen will appear similar to the example below. The
configuration settings will be loaded in normal order.
NOTE:
Dual-purpose (DHCP/TFTP) server utility software may require entry of the
configuration file name and path within the user interface. Alternatively, the DHCP software
may require creating a separate ext file with the configuration file name and path in a specific
directory on the server. Consult the documentation for the DCHP server software if users are
unsure.
