CISCO CNS NETWORK REGISTRAR 6.1
PRODUCT OVERVIEW
The Cisco CNS Network Registrar® provides IP address-management provisioning with highly scalable and reliable Domain Name System
(DNS), Dynamic Host Configuration Protocol (DHCP), and Trivial File Transfer Protocol (TFTP) services to help enable efficient and effective
provisioning of network devices and services. Its rich and extensible feature sets easily distinguish Cisco® CNS Network Registrar from DHCP
and DNS servers packaged with a commercial operating system. Cisco CNS Network Registrar can help reduce operational costs with the
central-management capability, which simplifies administrative tasks and reduces tedious and error-prone operations associated with network
and device configuration.
The Cisco CNS Network Registrar implements a complete DNS, DHCP, and TFTP server, and provides both graphically based and scriptable
command-line interface (CLI) administrative functions to help customers configure, automate, and simplify IP networking services. It supports
business-critical tasks such as client configuration and provisioning for numerous devices and service models for both service provider and
enterprise customers. Its ability to interoperate with Microsoft-based client devices and Active Directory allows customers to use the Cisco CNS
Network Registrar in a complementary role with the basic Microsoft DHCP and DNS servers.
The Cisco CNS Network Registrar automates common tasks such as IP address assignment and management, DHCP and client policy definition
and distribution, and day-to-day server maintenance to simplify IP network configuration and administration. Features such as the Lightweight
Directory Access Protocol (LDAP) directory interface facilitate integration of DNS and DHCP services with other network-management and
client- or service-provisioning applications. Performance-optimized functions provide fast setup and task execution, and an availability-tuned
architecture helps to ensure reliable and consistent client-services delivery.
NEW FEATURES
New features in Cisco CNS Network Registrar 6.1 include the following:
•
The regional cluster provides central-management capability in Cisco CNS Network Registrar. The regional cluster serves as the aggregate
management server for up to 100 local clusters, each of which is a collection of DNS, DHCP, and TFTP servers deployed in the network.
With regional cluster, the administrator can configure and control the local clusters from a centralized location, thus facilitating coordination
of local cluster management across multiple network domains to provide a consistent and unified IP address policy implementation.
•
Address-space management simplifies the task of managing address blocks and can be exercised from the regional cluster and is a feature in
the regional cluster. An administrator can break an address block into small units and push the smaller blocks to a local cluster. Similarly,
the administrator can also consolidate address blocks in the local cluster under their parent to provide a unified view of the address space.
Flexible reporting capability allows administrators, from the regional cluster, to collect subnet usage and lease history information stored in
local clusters deployed in the network, thus making the task of collecting usage data simple and virtually effortless. Without an automated
solution, the complexity of managing address blocks can be high and the task can be tedious and time-consuming.
•
Cluster management allows central management of address space and global protocol server configuration, such as policies, client classes,
and scope templates. With this capability, an administrator can create and manage a list of local clusters using the Web user interface on the
regional cluster. To further ease the administrative task, the administrator can centrally manage the local clusters, for example creating,
pulling, and pushing VPNs and managing DHCP client classes, scope templates and policies, failover pairs, and zone distribution. Through
