Chassis Configuration
Chassis configuration of the LI feature consists of two steps:
Configuration of the Legal Intercept request
Configuration of secure access
The Legal Intercept request can be configured directly using the C4/c CMTS and the
configure cable intercept
CLI
command. It can also be configured by setting the cTapMIB entries using SNMPv3.
The CLI and the SNMPv3 agent have simultaneous access to the same underlying cTapMIB object. Therefore, the operator
must manage simultaneous access appropriately. For security reasons the
cable intercept and show cable intercept
commands are password protected by the same user ID and password used to authorize remote SNMPv3 access to the
C4/c CMTS by the MD.
The userid and password created in the following procedure are set by the snmp-server command to restrict access to the
MIB view and are the same for the
configure cable intercept
command.
CLI Commands
The following section provides the commands used to create and manage secure access.
Sample Configuration for Secure Access and Tap
The following procedure serves as an example of how to create a view, group, and user for secure access. The names
chosen here for the view, group, and user are arbitrary.
To Configure a Secure Access and Tap
1.
To create the view to manage access:
configure snmp-server view <view-name> cTapMIB included
An example using a view named LI-TAP-VIEW:
configure snmp-server view LI-TAP-VIEW cTapMIB included
2.
To define the administrator group with read/write access:
configure snmp-server group <group_name> v3 noauth read <view_name> write <view_name> notify
<view_name>
