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 route convergence is not complete, a communication failure might occur. To address this issue, you can set a notification delay to avoid immediate notification of track entry state 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 track entry 101 associated with a Boolean OR list.

<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 to 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

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 determines the object to be Negative when the object is in Positive state. This keyword is supported only by a Boolean list.

weight weight: Assigns a weight in the range of 1 to 255 to the object. 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 are not allowed between track entries. 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-100] object 1

[Sysname-track-100] object 2 not

Parameters

negative negative-threshold: Specifies the negative state threshold in the range of 0 to 100. For the track entry to be set to the Negative state, the percentage of Positive objects must be equal to or smaller than the configured negative state threshold.

positive positive-threshold: Specifies the positive state threshold in the range of 0 to 100. For the track entry to be set to the Positive state, the percentage of Positive objects must be equal to or greater than the configured positive state threshold. The positive-threshold must be greater than the negative-threshold.

Usage guidelines

The track entry state 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 track entry associated with a percentage threshold list.

Examples

# Set the negative state threshold to 30% and the positive state threshold to 50% for track entry 1 associated with a percentage threshold list.

<Sysname> system-view

[Sysname] track 1 list threshold percentage

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

For the track entry to be set to the Positive state, the total weight of Positive objects must be equal to or greater than the configured positive state threshold. The positive-threshold must be greater than the negative-threshold.

Usage guidelines

The track entry state remains unchanged if the total weight of Positive objects is below the positive state threshold and above the negative state threshold.

·     The status of the monitored route entry is changed before the routing protocol completes the graceful restart.

You can resolve the problem by configuring the nonstop routing feature.

Parameters

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

and: Associates the track entry with a Boolean AND list.

or: Associates the track entry with a Boolean OR list.

Usage guidelines

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—When all objects in the list are in Positive state, the Track module sets the track entry to Positive state. When one or more objects are in Negative state, the Track module sets the track entry to Negative state.

·     Boolean OR list—When any object is in Positive state, the Track module sets the track entry to Positive state. When all objects are in Negative state, the Track module sets the track entry to Negative state.

To create a track entry, you must specify the tracked object type, which is list boolean in this command.

To enter the view of an existing track entry, use the track track-entry-number command. The tracked object type is not required.

To modify the settings of a track entry, execute the undo track command to remove the track entry, and then execute the track list boolean command again.

Parameters

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

Usage guidelines

The Track module determines the state of a track entry by comparing the percentage of Positive objects in the list with the percentage thresholds configured for the list. To configure the threshold values used to determine the track entry state, use the threshold percentage command.

To create a track entry, you must specify the tracked object type, which is list threshold percentage in this command.

To enter the view of an existing track entry, use the track track-entry-number command. The tracked object type is not required.

track list threshold weight

Use track list threshold weight to create a track entry associated with a weight threshold list and enter Track view, or enter the view of an existing track entry.

Use undo track to remove the track entry and all its settings.

Syntax

track track-entry-number list threshold weight

undo track track-entry-number

Default

No track entries exist.

Views

Predefined user roles

network-admin

Parameters

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

Usage guidelines

The Track module determines the state of a track entry by comparing the weight of Positive objects in the list with the weight thresholds configured for the list. To configure the threshold values used to determine the track entry state, use the threshold weight command.

To create a track entry, you must specify the tracked object type, which is list threshold weight in this command.

To enter the view of an existing track entry, use the track track-entry-number command. The tracked object type is not required.

To modify the settings for a track entry, execute the undo track command to remove the track entry, and then execute the track list threshold weight command again.

Examples

# Create track entry 101 and associate it with a weight threshold list.
