Cisco Cisco Prime Network Registrar 8.0 トラブルシューティングガイド

1 Introduction

1.1 Overview

NOTE: This document describes functionality that is available only in

Cisco Prime Network Registrar IP Address Management (IPAM) 8.0
and higher. In addition, this support exists for environments that are

running Cisco Prime Network Registrar IPAM Agents.
NOTE: This document describes Disaster Recovery support for the Cisco
Prime Network Registrar IPAM Executive running on supported Unix-

based platforms, Red Hat Linux, and Solaris. Disaster Recovery for the
Cisco Prime Network Registrar IPAM Executive is not supported on

Microsoft Windows platforms.

Environmental disasters, equipment failure, and power outages
are scenarios that can completely halt a company‟s IT
infrastructure. As part of the Cisco Prime Network Registrar

IPAM comprehensive Business Continuity and Disaster
Recovery (DR) solution, Cisco Prime Network Registrar IPAM

offers a complete set of script utilities that enables customers
to easily transition to backup systems during an emergency -

thus preventing negative impact to normal business operations.

1.2 Major Functions

As part of the standard installation, Cisco Prime Network
Registrar IPAM already provides facilities for DHCP Failover

and Secondary DNS server configuration. These facilities
ensure continuous operation of these critical network services.

During a DR event in which the Cisco Prime Network
Registrar IPAM Executive is affected, the DHCP/DNS

services continue to run autonomously, so end clients will
continue to operate. However, if the Executive is unavailable,

then configuration changes for DHCP/DNS cannot be made.
To address this need, the Cisco Prime Network Registrar

IPAM Executive can be configured for redundancy using the
DR guidelines and scripts described herein.
