The DHCP Auto Configuration page is used to perform the following actions when
the information is not provided in a DHCP message:
•Enable the DHCP auto configuration feature.
•Specify the download protocol.
•Configure the device to receive configuration information from a specific file
on a specific server.
Note the following regarding the DHCP auto configuration process:
•A configuration file that is placed on the TFTP/SCP server must match the
form and format requirements of the supported configuration file. The form
and format of the file are checked, but the validity of the configuration
parameters is not checked prior to loading it to the Startup Configuration.
•In IPv4, to ensure that the device configuration functions as intended, due to
allocation of different IP addresses with each DHCP renew cycle, it is
recommended that IP addresses be bound to MAC addresses in the DHCP
server table. This ensures that each device has its own reserved IP address
and other relevant information.
To configure auto configuration:
STEP 1 Click Administration > File Management > DHCP Auto Configuration.
STEP 2 Enter the values.
•Auto Configuration Via DHCP—Select this field to enable DHCP Auto
Configuration. This feature is enabled by default, but can be disabled here.
