xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CLI Manual

enable autoconfig

Purpose

Used to activate the autoconfiguration function for the Switch. This will

load a previously saved configuration file for current use.

Syntax

enable autoconfig

Description

When autoconfig is enabled on the Switch, the DHCP reply will contain a

configuration file and path name. It will then request the file from the

TFTP server specified in the reply. When autoconfig is enabled, the ipif

settings will automatically become DHCP client.

Parameters

None.

Restrictions

When autoconfig is enabled, the Switch becomes a DHCP client

automatically (same as:

config ipif System dhcp

). The DHCP server

must have the TFTP server IP address and configuration file name, and

be configured to deliver this information in the data field of the DHCP

reply packet. The TFTP server must be running and have the requested

configuration file in its base directory when the request is received from

the Switch. Consult the DHCP server and TFTP server software

instructions for information on loading a configuration file.

If the Switch is unable to complete the autoconfiguration process the

previously saved local configuration file present in Switch memory will be

loaded.

Only Administrator or Operator-level users can issue this command.

NOTE:

Dual-purpose (DHCP/TFTP) server utility software may require entry of the

configuration file name and path within the user interface. Alternatively, the DHCP software

may require creating a separate ext file with the configuration file name and path in a specific

directory on the server. Consult the documentation for the DCHP server software if you are

unsure.

Example usage:

To enable autoconfiguration on the Switch:

DES-3800:admin#enable autoconfig

Command: enable autoconfig

Success.

DES-3800:admin#

When autoconfig is enabled and the Switch is rebooted, the normal login screen will appear for a few moments while the autoconfig

request (i.e. download configuration) is initiated. The console will then display the configuration parameters as they are loaded from

the configuration file specified in the DHCP or TFTP server. This is exactly the same as using a

download configuration

command.

After the entire Switch configuration is loaded, the Switch will automatically “logout” the server. The configuration settings will be

saved automatically and become the active configuration.

Upon booting up the autoconfig process is initiated, the console screen will appear similar to the example below. The configuration

settings will be loaded in normal order.
