11.0 Dual IP Mode 11.1 Overview The IDH4 Series can operate in either Single (default) or Dual IP mode. In Single IP mode, data from both the cable modem and power supply are accessed and managed through the modem’s IP address on the secure private modem network. In Dual IP mode, the Communications Module acts like a CPE device to the cable modem and registers a second IP address on the public CPE network.
11.0 Dual IP Mode 11.2 Web Comparison, Single IP Mode/Dual IP Mode To easily determine the configuration of the Communications Module when viewing it on its web page, check the Configuration line as well as the entries for the CM and CPE addresses. A single IP Communications Module will display a CM MAC address only, while a Dual IP Communications Module will also indicate a CPE address. Displays CM MAC address only Fig.
11.0 Dual IP Mode 11.3 Configuring Dual IP Mode To switch the IDH4 Series Communications Module from Single to Dual IP mode the atiMgmtSnmpSnmpCPEAccess parameter of the Alpha MIB will need to be enabled. The Dual IP enable setting can be set through the DOCSIS Configuration File, the IDH4 Setup File (atidoc03.cfg), the Provisioning Mode via the Communications Web page or remotely using SNMP by setting the following Alpha MIB: MIB Parameter Object ID Description Value atiMgmtSnmpSnmpCPEAccess 1.3.6.1.
11.0 Dual IP Mode 11.3 Configuring Dual IP Mode, continued To change the CPE IP address allocation option from DHCP to Static via the Web Server, refer to the following: 1. Connect to IDH4 via Web browser per the procedure in Section 4.0, Web Interface. 2. In the Advanced Configuration menu of the Transponder Web page, click the Communications button. 3. Click the Static button in the CPE Communications Module column of the page. Refer to Figure 115.
11.0 Dual IP Mode 11.3 Configuring Dual IP Mode, continued 11.3.1 atidoc03.cfg in Dual IP Mode NOTE: Refer to Section 3.3.5 for details on using the atidoc03.cfg file to propagate custom settings to field-deployed IDH4x or IDH4L Communications Modules. In Dual IP mode, the Transponder will first attempt to download the proprietary configuration file atidoc03.cfg through the CPE’s interface from a TFTP server on the CPE network.
11.0 Dual IP Mode 11.3 Configuring Dual IP Mode, continued 11.3.3 Specifying atidoc03.cfg name and location via DHCP Tags In the User-defined area of the DHCP Tags, above option 192, the Communications Module will look for the following value: Tag: [Insert Unique Tag Name, e.g. ‘ati-tag’] Value: aticonfig In the Tag value immediately following will be the value for the TFTP server to use: Tag: [Insert Unique Tag Name, e.g. ‘ati-ip’] Value: IP address of TFTP server (i.e. 192.168.1.
11.0 Dual IP Mode 11.4 Dual IP SNMP Community Strings The Communications Module community strings used for the CPE Communications Module in Dual IP mode can be configured by the operator. The default Communications Module read-only community string is AlphaGet. The default read-write community string is AlphaSet. These settings can be configured with the DOCSIS Configuration File, the IDH4 Setup File (aitdoc03.
