Tracker Commands

boolean

To enable boolen logic while configuring a tracker group, use the boolean command in endpoint tracker configuration mode. To disable boolean logic, use the no form of this command.

boolean { and | or }

no boolean { and | or }

Syntax Description

{and | or}

Specifies boolean AND or OR logic that is used to configure a tracker group.

OR logic ensures that the endpoint status is reported as active if either one of the associated trackers of the tracker group report that the endpoint is active.

AND logic ensures that the endpoint status is reported as active if both the associated trackers of the tracker group report that the endpoint is active.

Command Default

OR is enabled.

Command Modes

Endpoint-tracker configuration (config-endpoint-tracker)

Command History

Release Modification

Cisco IOS XE Catalyst SD-WAN Release 17.7.1a

This command was introduced.

Usage Guidelines

Tracker boolean is set to OR as default.

A tracker group can have a mix of endpoint trackers. For example, to create a static route group, you can combine an IP address tracker and a TCP/UDP tracker. Similarly, to create a NAT Direct Internet Access (DIA) tracker group, you can combine an IP address tracker and a DNS tracker. You can apply only one tracker to a static route endpoint.

The following example shows how to configure a tracker group with two static route trackers (two endpoints) using the tracker boolean AND or OR: 


Device(config)# endpoint-tracker tcp-10001 
Device(config-endpoint-tracker)# tracker-type static-route 
Device(config-endpoint-tracker)# endpoint-ip 10.1.1.1 tcp 10001 
Device(config-endpoint-tracker)# threshold 100  
Device(config-endpoint-tracker)# multiplier 10 
Device(config-endpoint-tracker)# interval 1 
Device(config-endpoint-tracker)# exit 
Device(config)# track tcp-10001 endpoint-tracker
