Preparations for Using Auto Configuration from a TFTP Server
The Auto-Update feature enables configuring the device from a configuration
file found on the TFTP server.
Two methods may be used:
• One-file Read, described in Auto Configuration (One File Read Method).
This method is used if a configuration file is found on the TFTP server.
• Multi-file Read, described in "Auto Configuration (Multi File Read
Method)" on page 95. This method is used if a configuration file name is
not found on the DHCP server, or the configuration file is not found on
the TFTP server.
Auto Configuration (One File Read Method)
This method requires the following preparations on the DHCP and TFTP
servers:
•TFTP Server
Place a configuration file, for example config.txt in the main 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 option 67 and the name of the
configuration file on the TFTP server (for example,
config.txt ).
– Configure the DHCP server with the IP address of the TFTP server.
The TFTP server can be configured in one of the fields listed below.
These fields are listed by order of priority by which information is
taken, meaning that information is taken by the device from the lower
priority option only if information does not exist in the higher priority
option.
• 1. sname (Server Host Name)
•2. Option 66
• 3. Option 150
• 4. Option 129 (called server IP address)
• 5. siaddr (IP address of next server)
