13.0 Dual IP Mode (Addendum) 13.1 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 transponder acts like a CPE device to the cable modem and registers a second IP address on the public CPE network.
13.0 Dual IP Mode (Addendum), continued 13.2 Web Comparison, Single IP Mode/Dual IP Mode To easily determine the configuration of the transponder 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 transponder will display a CM MAC address only, while a Dual IP transponder will also indicate a CPE address. Indicates 1 IP address: "Single IP" Status Monitor Displays CM MAC address only Fig.
13.0 Dual IP Mode (Addendum), continued 13.3 Configuring Dual IP Mode To switch the IDH4 Series transponder 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 (idhdoc04.cfg), the Provisioning Mode via the Communications Web page or remotely using SNMP by setting the following Alpha MIB: MIB Parameter Object ID atiMgmtSnmpSnmpCPEAccess 1.3.6.1.4.1.926.
13.0 Dual IP Mode (Addendum), continued 13.3 Configuring Dual IP Mode, continued 13.3.1 idhdoc04.cfg in Dual IP Mode NOTE: 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. 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.
13.0 Dual IP Mode (Addendum), continued 13.3 Configuring Dual IP Mode, continued 13.3.3 Specifying idhdoc04.cfg name and location via DHCP Tags In the User-defined area of the DHCP Tags, above option 192, the TRANSPONDER 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.
13.0 Dual IP Mode (Addendum), continued 13.4 Dual IP SNMP Community Strings The transponder community strings used for the CPE Transponder in Dual IP mode can be configured by the operator. The default transponder 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.
13.0 Dual IP Mode (Addendum), continued 13.5 Security in Dual IP Mode, continued Method 2: Dual IP Security Using the Secure Access List The IDH4 provides an alternative method of providing additional SNMP security in Dual IP by limiting access to the transponder’s CPE address. The Secure Access List method limits remote SNMP access to four IP addresses. Only the IP addresses listed in the SNMP Access Table are able to read or write to the Alpha MIB parameters from the public (CPE) network.
