Associating Track with a Boolean list
About Boolean list
A Boolean list is a list of tracked objects based on a Boolean logic. It can be further divided into the following types:
Boolean AND list—A Boolean AND list is set to the positive state only when all objects are in positive state. If one or more objects are in negative state, the tracked list is set to the negative state.
Boolean OR list—A Boolean OR list is set to the positive state if any object is in positive state. If all objects are in negative state, the tracked list is set to the negative state.
Procedure
To associate Track with a Boolean list:
Step | Command | Remark |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Create a track entry. | Create a track entry before you add it as a tracked object to a tracked list. A minimum of one track entry must be created. | |
3. Create a Boolean tracked list and enter its view. | track track-entry-number list boolean { and | or } | By default, no tracked lists exist. |
4. Add the track entry as an object to the tracked list. | object track-entry-id [ not ] | By default, a tracked list does not contain any objects. Repeat this step to add all interested objects to the tracked list. |
5. (Optional.) Set the delay for notifying the application module of tracked list state changes. | delay { negative negative-time | positive positive-time } * | By default, the Track module notifies the application module immediately when the tracked list state changes. |
