DHCP Auto Configuration

DGS-3100 Series Gigabit Stackable Managed Switch User Manual

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:

Figure 2-19 DHCP Auto Configuration Page

The DHCP Auto Configuration Page contains the following fields:

Field

DHCP Auto Configuration

Description

Specifies whether the device gets an updated image file, and updated configuration file through the DHCP Server whenever the device reboots. The DHCP server maintains the TFTP Server IP address, where the files are saved. The possible field values are:

•Enabled — Enables automatic updates from the DHCP server.

•Disabled — Disables automatic updates from the DHCP server. This is the default value.

2.Select Enabled to turn on DHCP Auto configuration or Disabled to turn it off. Disabled is the default.

3.Click. The DHCP automatic configuration update is modified, and the device is updated.
