Track commands

delay

Use delay to set the period of time that the Track module must wait before notifying the application module of track entry state changes.

Use undo delay to remove the notification delay configuration.

Syntax

delay { negative negative-time | positive positive-time } *

undo delay

Default

The Track module notifies the application module immediately when the track entry state changes.

network-admin

Parameters

negative negative-time: Specifies the delay for notifying the application module that the track entry state has changed to negative. The negative-time argument represents the negative state notification delay in the range of 1 to 300 seconds.

positive positive-time: Specifies the delay for notifying the application module that the track entry state has changed to positive. The positive-time argument represents the positive state notification delay in the range of 1 to 300 seconds.

Usage guidelines

If the Track module immediately notifies the application module of a track entry state change but the route convergence is not complete, a communication failure might occur. In such cases, you can set a notification delay to avoid immediate notification of track entry status changes.

The notification delay settings do not take effect if the track entry is not associated with an application module.

If you execute this command multiple times, the most recent configuration takes effect.

Examples

# Set the negative state notification delay to 50 seconds and the positive state notification delay to 120 seconds for Boolean OR tracked list 101.

<Sysname> system-view

[Sysname] track 101 list boolean or

[Sysname-track-101] delay negative 50 positive 120

object

Use object to add a track entry as an object to a tracked list.

Use undo object remove the object from a tracked list

Syntax

object track-entry-number [ not ] [ weight weight ]

undo object track-entry-number

Default

A tracked list does not contain any objects.

Views

Track view

Predefined user roles

network-admin

Parameters

track-entry-number: Specifies a track entry by its ID in the range of 1 to 1024.

not: Negates the state of the object. For example, the tracked list regards the object as negative when the object is in positive state. This keyword is supported only by a Boolean list.

weight weight: Assigns a weight to the object, in the range of 1 to 255. This keyword is supported only by a weight threshold list. The default weight is 10.

Usage guidelines

The track entry ID of the object cannot be the same as the ID of the tracked list to which the object is added.

You can add a maximum of 16 objects to a tracked list.

Loops between track entries are not allowed. For example, after you add track entry 1 (object 1) to tracked list 2 and track entry 2 (object 2) to tracked list 3, you cannot add track entry 3 (object 3) to tracked list 1 because a loop will be created.

Examples

# Create Boolean AND list 100 and add track entries 1 and 2 as tracked objects to the list.

<Sysname> system-view

[Sysname] track 100 list boolean and

[Sysname-track-101] object 1

threshold percentage

Use threshold percentage to set the threshold values used to determine the state of a percentage threshold list.

Use undo threshold percentage to restore the default.

Syntax

Predefined user roles

network-admin

Parameters

negative negative-threshold: Specifies the negative state threshold, in the range of 0 to 99. The percentage of positive objects must be equal to or smaller than the configured negative state threshold for the tracked list to be set to the negative state.

The percentage of positive objects must be equal to or greater than the configured positive state threshold for the tracked list to be set to the positive state. The positive-threshold must be greater than the negative-threshold.

Usage guidelines

The state of a percentage threshold list remains unchanged if the percentage of positive objects is below the positive state threshold and above the negative state threshold.

This command is supported only by a percentage threshold list.

Examples

# Set the negative state threshold to 30% and the positive state threshold to 50% for percentage threshold list 1.

<Sysname> system-view

[Sysname] track 1 list threshold percentage

[Sysname-track-1] threshold percentage negative 30 positive 50

Parameters

negative negative-threshold: Specifies the negative state threshold in the range of 0 to 254. The total weight of positive objects must be equal to or smaller than the configured negative state threshold for the tracked list to be set to the negative state.
