13.0 Dual IP Mode (Addendum)
13.3.1 atidoc03.cfg in Dual IP Mode
In Dual IP mode, the DSM3 Series will first attempt to download the proprietary configuration
file atidoc03.cfg through the CPE’s interface from a TFTP server on the CPE network. In many
networks, the TFTP server is blocked or disabled, so the DSM3 Series also has provisions to
download this file through the Cable Modem interface from the modem’s provisioning server if
necessary. The filename and TFTP server location may also be specified through special tags
in the DHCP Offer, refer to
Section 13.3.3, Specifying atidoc03.cfg Name and Location via
DHCP Tags for details. Similiar to Single IP mode, any DSM3 Series proprietary SNMP MIB
setting may be placed in the modem’s DOCSIS configuration file which would eliminate the need
for atidoc03.cfg.
13.3.2 Changing Default atidoc03.cfg Download Settings in Dual IP Mode
The following table explains the download options available for the atidoc03.cfg file in Dual IP
mode. The ‘Download Interface’ indicates the network from which the DSM3 series will attempt
to download atidoc03.cfg, either the CPE network or the more secure cable modem management
network.
Refer to Section 3.3.5 for details on using the atidoc03.cfg file to propagate custom settings to
field-deployed DSM3 Series Communications Modules.
