Command History
Usage Guidelines
This command sets the Software Upgrade Filename and Software Upgrade TFTP Server fields in the
DOCSIS configuration file. The DOCSIS specification allows the DOCSIS configuration file to specify
that the CM must be running a particular software image. If the CM is not currently using that image, it
must then download the image before continuing the registration process. For security, performance, and
scalability reasons, a particular TFTP server can be specified from which the CM must download the
new software image.
image
filename
Specifies to download an image file.
oui
oui-list
Specifies the list of Organizational Unique Identifiers (OUIs), up to a
maximum of 8. (An OUI is the first 3 octets of the CM MAC address and
typically indicates the vendor for the CM.)
Tip
The Institute of Electrical and Electronics Engineers (IEEE) is the
official issuer of OUI values. The IEEE OUI web site is at
http://standards.ieee.org/regauth/oui/index.shtml
.
server
ip-address
Specifies the TFTP server IP address. If no IP address is specified, the CM
defaults to using the same TFTP server that provided the configuration file.
