13.3.1 idhdoc04.cfg in Dual IP Mode

In Dual IP mode, the IDH4 Series will rst attempt to download the proprietary conguration le

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 le through the Cable Modem interface from the modem’s provisioning server if

necessary. The lename and TFTP server location may also be specied 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 conguration le which would eliminate the need for

idhdoc04.cfg.

Refer Section 3.2.4, Proprietary Conguration File idhdoc04.cfg for details on using the

idhdoc04.cfg le to propagate custom settings to eld-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 le 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.
