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 6-114. 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. - Disable - Uses the configuration file as the running configuration only. When the switch reboots, it will load the configuration from the startup configuration file. • Retry Count - Indicates the number of times to attempt the auto configuration process during boot up. The number of times the switch has attempted to contact the TFTP server during the current Auto Configuration session. • Auto Configuration State - Shows the current state of the Auto Configuration process.

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.

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

it will load the configuration from the startup configuration file.

•

Retry Count

— Indicates the number of times to attempt the auto configuration process during boot

up. The number of times the switch has attempted to contact the TFTP server during the current

Auto Configuration session.

•

Auto Configuration State —

Shows the current state of the Auto Configuration process.
