DHCP Auto Configuration
In the DHCP Auto Configuration Page, users can enable or disable automatic download of the latest image and
configuration files from the DHCP server. During reboot, if DHCP Auto Configuration is enabled, the device polls the
TFTP Server. From the DHCP server, the device receives the following, if necessary:
IP address – The device will receive IP from the DHCP server regardless of current IP configuration (whether
static or dynamic). If the device already has a DHCP-defined IP address, it will retain the current address. If
Static IP is present in the configuration file, it will be ignored.
Image file – If an updated image file is available on the network, and the DHCP server’s latest instruction file
refers to it, the device downloads the image file.
Configuration file – If an updated configuration file is available on the network, and the DHCP server’s latest
instruction file refers to it, the device downloads the file as its new Running Configuration, and also saves it as the
Startup Configuration. If Static IP is present in the configuration file, it will be ignored.
To enable DHCP Auto Configuration:
1. Click Configuration > DHCP Auto Configuration. The
DHCP Auto Configuration Page opens:
