• Configure the switch 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 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, different IP addresses are allocated with each DHCP renewal cycle.
To ensure that the device configuration functions as intended, we
recommend that IP addresses be bound to MAC addresses in the DHCP
server table.
NOTE DHCP Auto Configuration is applicable only when the IP address of the switch is set
to dynamic.
To configure DHCP Auto Configuration:
STEP 1 Click Administration > File Management > DHCP Auto Configuration.
STEP 2 Enter the following information:
• Auto Configuration via DHCP—Check Enable to enable the DHCP Auto
Configuration feature on the switch, or uncheck to disable this feature.
• Backup Server Definition—Select whether to specify the TFTP server by
IP address or domain name.
• IP Version—Select either Version 4 or Version 6 if the TFTP server is
identified by IP address.
• Backup TFTP Server IP Address/Name—Enter the IP address or domain
name of the backup TFTP server. If no configuration file name is specified in
the DHCP message, the switch will download the backup configuration file
from the backup TFTP server.
• Backup Configuration File—Enter the full file path and name of the
configuration file on the backup TFTP server to be used if no configuration
file name is specified in the DHCP message.
• Last Auto Configuration TFTP Server IP Address—Displays the IP
address or domain name of the TFTP server that is currently using.
• Last Auto Configuration File Name—Displays the name of the
configuration file located on the TFTP server that is currently using.
