4.2.5 Configuring DHCP Auto Install
This feature is used to download configuration files and images from the TFTP server
automatically. It requires a TFTP server and a DHCP server that supports option 67,
125 and 150 on your network. When Auto Install function starts, the switch tries to get
configuration file name, image file path and TFTP server IP address from the DHCP server,
and then downloads the new image and configuration file form the TFTP server.
Follow these steps to configure the DHCP Auto Install.
Step 1 configure
Enter global configuration mode.
Step 2 boot autoinstall persistent-mode
Enable the auto install persistent mode. After saving configuration, the switch will start the
Auto Install function automatically during next reboot process.
