Automatically Downloading a Configuration File
You can automatically download a configuration file to your switch by using the DHCP-based
autoconfiguration feature. For more information, see the “DHCP-Based Autoconfiguration” section on
page 2-3.
Specifying the Filename to Read and Write the System Configuration

system configuration. However, you can specify a different filename, which will be loaded during the
next boot cycle.
