Auto Image and Configuration Update

Auto Configuration Example

A network administrator is deploying three PowerConnect switches and wants

to quickly and automatically install the latest image and a common

configuration file that configures basic settings such as VLAN creation and

membership, RADIUS server settings, and 802.1X information. The

configuration file also contains the command boot host autosave so that the

downloaded configuration is automatically saved to the startup config.

Enabling DHCP Auto Configuration and Auto Image Download

If no configuration file is found during the boot process, the Auto

Configuration feature uses the DHCP Auto Configuration process to

download the configuration file to the switch. This example describes the

procedures to complete the configuration.
To use DHCP auto configuration:

1 Create a default config file for the switches named host.cfg. For

information about creating configuration files, see Managing Images and

Files.

2 Upload the host.cfg file to the TFTP server.
3 Upload the image file to the TFTP server.
4 Configure an address pool on the DHCP server that contains the following

information:

a

The IP address (

yiaddr

) and subnet mask (option 1) to be assigned to

the interface

b

The IP address of a default gateway (option 3)

c

DNS server address (option 6)

d

Name of config file for each host

e

Identification of the TFTP server by hostname (DHCP option 66 or

the

sname

field in the DHCP header) or IP address (DHCP option

150 or the

siaddr

field in the DHCP header)

f

Name of the text file (option 125, the V-I vendor-specific Information

option) that contains the path to the image file.
