Auto Image and Configuration Update
Enabling DHCP Auto Configuration and Auto Image Download
If no USB device is connected to the USB port on the PowerConnect switch
and 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.
5
Connect a port (OOB port for out-of-band management or any switch port
for in-band management) on each switch to the network.
6
Boot the switches.
