Before You Start
To use this feature, the device must either be configured as a DHCPv4 or DHCPv6
client. The type of DHCP client defined on the device is in correlation with the type
of interfaces defined on the device.
Auto Configuration Preparations
To prepare the DHCP and TFTP/SCP servers, do the following:
TFTP/SCP Server
•
Place a configuration file in the working directory. This file can be created
by copying a configuration file from a device. When the device is booted,
this becomes the Running Configuration file.
DHCP Server
Configure the DHCP server with the following options:
•
DHCPv4:
-
66 (single server address) or 150 (list of server addresses)
-
67 (name of configuration file)
•
DHCPv6
-
Option 59 (server address)
-
Options 60 (name of configuration file plus indirect image file name,
separated by a comma)
Auto Image Update Preparations
To prepare the DHCP and TFTP/SCP servers do the following:
TFTP/SCP Server
1. Create a sub directory in the main directory. Place a software image file in it.
2. Create an indirect file that contains a path and the name of the firmware version
(for example indirect-cisco.txt that contains cisco\cisco-version.ros).
3. Copy this indirect file to the TFTP/SCP server’s main directory
DHCP Server
Configure the DHCP server with the following options
•
DHCPv4—Option 125 (indirect file name)
