Configuring clusters has many similarities to configuring standalone devices. You can
use NSM to configure cluster objects either directly through regular configuration or
through templates. JUNOS device clusters can also use configuration groups to define
cluster data, just as for standalone JUNOS devices.
For Screen OS/IDP clusters, Secure Access clusters, and Infranet Controller clusters,
most of the configuration information is the same among the various members. However,
there are some differences that are configured separately on each cluster member.
JUNOS clusters are different in that the configuration on each JUNOS cluster member is
identical. These clusters use a special implementation of the configuration group
mechanism to maintain differences between the members, but within the same
configuration file.
Although you cannot edit the configuration of a cluster member, you can view its
configuration. In the Info tab of the open cluster, select Members. Icons representing the
members of the cluster appear in the main display area. Select the cluster member you
want to view, and click the Edit icon to display the cluster member configuration.
After editing the cluster configuration, you push the edited configuration to the cluster
using the Update Device directive. The cluster ensures that all members are synchronized.
For all device families, you can edit the cluster configuration by selecting the cluster icon
in the Device Manager and clicking the Edit icon. You then apply edits to the cluster as
you would to a standalone device. See "Editing Devices Using the Device Editor" on
page 188 for details about editing a configuration.
To configure a cluster object using a template:
In the Device Manager, select Devices.
