Configuring Network Registrar and a CMTS
For BACC to function, you need to set up Network Registrar client-classes, policies, scopes, and
selection tags. You also need to perform some configuration of CMTS devices.
To configure Network Registrar and CMTS devices, complete these steps:
Set up scopes on your Network Registrar server. For example:
Step 1
<NR_HOME>/usrbin/nrcmd -N <USER_NAME> -P <PASSWORD> -b <
<BACC_HOME>/cnr_ep/samples/bpr_cnr_hsd_sample_config.nrcmd
Note
Step 2 Enable the cable interface or interfaces on your CMTS with the correct IP addresses and DHCP
helper-address. For example, you might edit the CMTS configuration as follows:
interface Cable3/0

The <BACC_HOME>/cnr_ep/samples/bpr_cnr_hsd_sample_config.nrcmd command runs a
sample Network Registrar configuration script, which defines client-classes, policies, scopes,
selection tags and other related information. You must update this file to reflect the IP address
settings on your network. For more information about this file, see
Configuration File Example". For more detailed information about defining client-classes,
policies, scopes, and selection tags, see the Network Registrar User's Guide.

use these IP addresses in an operational environment.
