• The IP addresses of DNS name servers (option 6). The IP addresses of DNS name servers should be
returned from the DHCP server only if the DNS server is in the same LAN as the switch performing
Auto Configuration. A DNS server is needed to resolve the IP address of the TFTP server if only the
"sname" or option 66 values are returned to the switch.
After obtaining IP addresses for both the switch and the TFTP server, the Auto Configuration feature
attempts to download a host-specific configuration file using the boot file name specified by the DHCP
server. If the switch fails to obtain the file, it will retry indefinitely.
Use the Auto Configuration page to enable the switch to be automatically configured when it is
initialized and cannot find a configuration file. With Auto Configuration enabled, the switch obtains an
IP address and downloads a configuration file from a TFTP server.
NOTE: The Auto Configuration process requires the DHCP client on the switch to be enabled by default. The Auto
Configuration feature also depends upon the configuration of other devices in the network, including a DHCP or
BOOTP server, a TFTP server and, if necessary, a DNS server.
To display the Auto Configuration page, click System → Advanced Settings → Auto Configuration in the
tree view.
Figure 6-110. Auto Configuration
The Auto Configuration page contains the following fields:
• Auto Configuration Mode — Enables (Start) or disables (Stop) the Auto Configuration feature on
the switch. Select Start to initiate sending a request to a DHCP server to obtain an IP address of a
server and the configuration file name. If it obtains the server address, Auto Configuration proceeds to
search for and download a configuration file from the server. If successful, it applies the configuration
file to the switch. After starting the Auto Configuration process, you can monitor the status of the
process by the messages in the Auto Configuration State and Retry Count fields.
Auto Save Mode — Specifies whether to save the automatically downloaded configuration file to the
•
startup configuration.
Enable — Automatically saves the configuration file to the startup configuration.
