13.3.1 idhdoc04.cfg in Dual IP Mode
In Dual IP mode, the IDH4 Series will first attempt to download the proprietary configuration file
idhdoc04.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 IDH4 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 idhdoc04.cfg Download Settings in Dual
IP Mode for details. Similiar to Single IP mode, any IDH4 Series proprietary SNMP MIB setting
may be placed in the modem’s DOCSIS configuration file which would eliminate the need for
idhdoc04.cfg.
Refer Section 3.2.4, Proprietary Configuration File idhdoc04.cfg for details on using the
idhdoc04.cfg file to propagate custom settings to field-deployed IDH4 Series transponders.
NOTE:
13.3.2 Changing Default idhdoc04.cfg Download Settings in Dual IP Mode
Table 13-3 explains the download options available for the idhdoc04.cfg file in Dual IP mode. The
‘Download Interface’ indicates the network from which the IDH4 series will attempt to download
idhdoc04.cfg, either the CPE network or the more secure cable modem management network.
