The
DHCP Auto Configuration
page can be used to configure the switch to receive
DHCP information from a specific file on a specific TFTP server, in the following
cases:
•
The information was not provided in a DHCP message.
•
For manual configuration.
Note the following regarding the DHCP auto-update process:
•
A configuration file that is placed on the TFTP server must match the form
and format requirements of a 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.
•
To ensure that the device configuration functions as intended, due to
allocation of different IP addresses with each DHCP renew cycle, IP
addresses must 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.
