The Exclude Node Feature


Overview

Initially, the Listener/LGMapper installation sets up the Exclude Node feature so that it is disabled. This is done to provide backwards compatibility with older Grid clients. The Exclude Node feature is incompatible with the Grid application, and would create inconsistent views of Alarm objects in Grid if it were enabled. For this reason, Listener uses a registry setting to determine if the Excluded Node feature is enabled or not.

When Exclude Node is disabled (the default), Grid clients and AlarmTracker clients can be used simultaneously. However, when an AlarmTracker user attempts to exclude a node, an error dialog appears indicating that this feature is not enabled.

When the Exclude Node feature is enabled, Grid clients connect to the Listener, but receive no data other than Listener heartbeats. An Alarm is also raised in the AALSTN customer node.

Enabling the Exclude Node Feature

To enable the Exclude Node feature in Listener, you must create a registry value as follows:

Key: HKEY_LOCAL_MACHINE\SOFTWARE\Cisco Systems, Inc.\ICM\Listener

DWORD Value: SupportExcludeNode = 1

If this value is not present, or has a value other than 1, the Exclude Node feature is disabled.
