Connect Multiple NNMi Management Servers (NNMi Advanced)

The Global Network Management feature enables you to configure NNMi to share the workload among multiple NNMi management servers in your network environment. For more information about the Global Network Management feature,  click here.

(NNMi Advanced) There are many benefits to using the NNMi Global Network Management feature:

• Provides safe and secure communication among multiple NNMi management servers.
• Provides a central big-picture view of your corporate-wide network on the Global Manager for 24-hour/7-days-per-week coverage.

• Enables management of nodes that are configured with address translation protocols to provide their public address (resulting in overlapping addresses domains). An NNMi Regional Manager is required for each address domain configured with following protocols:

  • Static Network Address Translation (NAT)
  • Dynamic Network Address Translation (NAT)
  • Dynamic Port Address Translation (PAT/NAPT)

• Easy to set up:

  • Each Regional Manager administrator specifies all Node object data or a specific Node Group for participation at the Global Manager level.
  • Each Global Manager administrator specifies which Regional Managers are permitted to contribute information.
• Automatically combines topology from multiple NNMi management servers on the Global Manager, but keeps management responsibilities separate. (No duplication, the responsible NNMi Management server is clearly identified per Node.)
• Generates and manages Incidents independently on each server (generated within the context of topology available on each server).
• Regional Manager administrators can configure specific SNMP Traps to be forwarded from Regional Managers to Global Managers.

Review the Global Network Management deployment choices in the Network Node Manager i Software Deployment Reference (available at: https://softwaresupport.softwaregrp.com/).

All NNMi management servers in your network environment that participate in Global Network Management (Global Managers and Regional Managers) or Single Sign-On (SSO) must have their internal time clocks synchronized in universal time.

Caution Use a Time Synchronization program, for example, the Linux tool Network Time Protocol Daemon (NTPD) or one of the available Windows operating system tools.

To configure Global Network Management, do the following:

1. Navigate to the Global Network Management form.

   1. From the workspace navigation panel, select the Configuration workspace.
   2. Select Global Network Management.

2. Do one of the following:

   • Regional Manager Configuration:

     If you are the NNMi administrator for the Regional Manager, you control the following aspects of communication with the Global Manager:

     • Configure a Tenant for each address domain. The Tenant name must be unique across all Tenants in the Global Network Management domain.

     • Forward information about all Node object data or only data about Nodes belonging to one Node Group.

       Note Incidents associated with the specified Nodes are not forwarded to the Global Manager. Each server maintains an independent group of incidents.

   • Global Manager Configuration:

     If you are the NNMi administrator for the Global Manager, decide which Regional Managers are permitted to forward network information to that Global Manager (NNMi management server). Each Regional Manager retains management responsibilities for the forwarded nodes. The Global Manager might or might not directly manage a set of network devices.
