Method 2: Dual IP Security Using the Secure Access List
The DSM3 provides an alternative method of providing additional SNMP security in Dual IP by limiting access to
the Communications Module’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. This method overrides the default "Data Access Key" method.
The IP address entries in the SNMP Access Table can be set through the DOCSIS Configuration File, the DSM3
Setup File (atidoc03.cfg) or remotely using SNMP by including the following Alpha MIB parameters:
