Security in Dual IP Mode

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:
