NEW FEATURES
New features in Cisco Network Registrar 6.2 include the following:
●
DHCPv6 and DNSv6 to enable users to test and deploy IPv6 services—DHCPv6 provides basic address assignment, prefix delegation, and
stateless autoconfiguration using IPv6 addressing. Cisco Network Registrar 6.2 supports DHCPv6 for clients, client classes, static
reservations, policies, and options—and it supports prefixes and links. The DHCPv6 service was added to the existing DHCP server, not to
comprise a separate server, but to take better advantage of the DHCP functions and infrastructure where possible. The solution provides a
DNS server that supports AAAA and pointer (PTR) resource records and ip6.arpa reverse zones, and DNS client query resolution over
IPv6 transport, in the Web user interface and command-line interface (CLI).
●
High-Availability DNS main and backup (standby) server configurations—The High-Availability DNS solution introduces a primary DNS
standby server that shadows the primary active server, providing failover redundancy for DNS updates whenever there is a server outage or
any disruption in communication. The DHCP server was also enhanced to support updates to either the active or standby server. Without
High-Availability DNS, users could deploy only one primary DNS, a potential single point of failure.
●
Dynamic scope management—Dynamic scope management allows the Cisco Network Registrar administrator to make dynamic changes to
the scopes and have the changes become effective immediately without a server reload. This feature increases the Cisco Network Registrar
DHCP server uptime to handle critical applications that are intolerable to slow response. The feature can also help increase operational
efficiency, especially in the case where changes to scopes are frequently made. The reload time compounded over a period of time can
become significant and result in low customer satisfaction.
●
DHCP load-balancing failover—Cisco Network Registrar 6.2 supports DHCP load-balancing failover deployment in which the backup
DHCP server can offload a percentage of the DHCP request population. With this support, users can take better advantage of the CPU
resources on both servers; this support also can result in shorter response time when processing DHCP requests.
●
Extended lease reservation—Cisco Network Registrar 6.2 allows users to configure lease reservation using information other than MAC
address. If the device breaks down and has to be replaced, users can replace the broken device with a new one without having to
reconfigure the lease reservation for the new device.
●
Full DNS administrative operations from the regional cluster—This feature includes complete management of forward and reverse zone,
resource records, host records, and full access to the local cluster DNS server. Although DNS administration is possible from the regional
cluster, the local administrator can still have custom configuration of the DNS for specific zones. This feature gives the regional cluster
administrator full access to configure the DNS servers deployed in the network and provides the administrator a more efficient way to
manage DNS servers from a central location, hence reducing operational cost.
●
Simple Network Management Protocol (SNMP) manageability—Cisco Network Registrar 6.2 helps users manage the DNS and DHCP
servers through a built-in SNMP agent. Users can retrieve solicited information in addition to traps from DHCP and DNS servers. With a
single console to manage various applications, users see a dashboard displaying the health of all the critical applications and resources.
●
Enhanced option handling—Cisco Network Registrar 6.2 reduces the complexity of creating the user’s own DHCP option definition by
allowing the user to easily add, modify, and delete option and suboption definitions from the base DHCPv4 and DHCPv6 specification
using the Web interface.
●
Flexible DNS update policy—Cisco Network Registrar 6.2 provides a policy-based mechanism to update resource records. Rather than solely
relying on access control lists (ACLs), the solution helps the user create a policy to specify the criteria used to process update requests. In
each policy, the user indicates the type of resource record, ACL, grant or deny access, and additional information used to match the
resource records.
●
Central backup and restoration of configuration—To help users protect the configuration information maintained on the local cluster, Cisco
Network Registrar 6.2 helps users back up the configuration data and archive this information in the regional cluster database. If a
