CNR v7.0-BAC v4.0 - Cisco Network Registrar/Broadband Access Center Combo Class
Duration:
Description
The Cisco CNR / BAC course is an instructor-led
five-day course focusing on learning skills required to configure DNS,
DHCP, and device bootfiles for DOCSIS and PacketCable Customer Premise
Equipment, using Cisco Network Registrar (CNR) and Cisco Broadband
Access Center application server suites . IP Address Management of
traditional computer clients like Personal Computers, workstations,
printers and mobile devices will also be covered.
The ideal candidate would be someone who has worked
in a data network or Cable Provider DOCSIS environment but lacks hands
on experience configuring Cisco DNS, DHCP, and device provisioning
products. This course will serve to educate students on the protocols
and configuration. For candidates working in an Enterprise or Campus
(not Cable Service Provider) environment, the first 3 days comprise a
standalone CNR course. Personnel who support Cable MSO’s should attend
all 5 days.
Students will receive extensive hands-on experience
in addition to lecture. Each student will configure their own DHCP,
DNS, and BAC server. Students will run simulation tools to simulate
booting DOCSIS cable modems and PCs on a network. Testing will include
high availability architectures for DHCP, DNS and device provisioning
for Cable Service Provider, Enterprise, and Campus environments.
Objectives
Install CNR and BAC in a Sun hardware environment.
Describe the DNS protocol and how it is used to perform hostname resolution.
Describe the different types of DNS server configurations for
extending the reach of a LAN and the methods that can be used with a
focus on RF wireless access.
Use both the command-line interface and web user interface to configure DHCP and DNS objects.
Configure CNR DNS and DHCP for an IPv6 environment.
Configure DHCP objects for multiple scopes, policies, and networks.
Perform system administration duties for CNR and BAC software running in each of the supported operating systems.
Configure CNR and BAC to support classes of service for network devices.
Describe the feature set and functionality of Cisco Broadband Access Center.
Describe the boot-up sequence of DOCSIS Cable Modems and other network devices behind the CM.
Describe the different types of servers which make up the Head-End and Regional Data Center in a BAC and CNR environment.
Use tools to simulate cable modems booting on a network and getting proper configurations to allow network communications.
Troubleshoot problems within a provisioning environment that would prevent cable modems from receiving device configurations.
