Infranet Controllers Clusters in NSM Overview

When you add an Infranet Controller cluster in NSM, you first add the cluster object and then add each member. Adding a member is similar to adding a standalone device.

Infranet Controller clusters can be configured by the device administrator to operate in active/passive mode or in active/active mode. Clusters in active/passive mode are made up of a primary member and a secondary member. All authentication requests are handled by the primary member. If a primary member fails, then the secondary member takes over.

In active/active mode, authentication requests are load-balanced across all cluster members. If one member fails, then load balancing takes place among the surviving members.

The number of members permitted in a cluster depends on the Infranet Controller platform and whether the cluster is configured in active/active mode or in active/passive mode. You can have no more than two cluster members in active/passive mode. In active/active mode you can have up to four members.

Before you can add a cluster member in NSM, the device administrator must have already created the cluster and added, configured, and enabled the physical cluster member. See the Juniper Networks Unified Access Control Administration Guide for details on creating and configuring clusters.

Infranet Controller devices configured in a cluster must have a cluster object and member objects defined in the NSM before the Infranet Controller Cluster nodes can be recognized by NSM. Nodes from this cluster that subsequently contact NSM will be represented by fully functional member icons in the Cluster Manager. Cluster members whose DMI agents do not contact NSM will be displayed in the NSM Device Monitor as unconnected devices.

Infranet Controller devices use member IDs to identify each cluster member object. When importing cluster members, the member ID is imported as part of the cluster, so the Add Cluster Member wizard does not prompt for the member ID.

To add an Infranet Controller cluster to NSM, first add the cluster object, and then add its members. You add cluster members one at a time, in a similar manner to adding standalone devices.

Once an Infranet Controller cluster is managed by NSM, subsequent changes applied to the cluster by NSM will be synchronized by the cluster across all cluster members. Similarly, changes to an Infranet Controller cluster membership that occur through administrator action on the native device UI will be reflected back to NSM, and NSM will display the modified cluster after the cluster configuration is imported to NSM.

You can add an Infranet Controller cluster from your existing network into NSM and import their configurations. Using the Add Device Wizard, you configure a connection between the management system and the physical device, and then import all device parameters.
