carrier-delay (tracking) through forwarding-agent

carrier-delay (tracking)

To enable Enhanced Object Tracking (EOT) to consider the carrier-delay timer when tracking the status of an interface, use the carrier-delay command in tracking configuration mode. To disable EOT from considering the carrier-delay timer when tracking the status of an interface, use the no form of this command.

carrier-delay

no carrier-delay

Syntax Description

This command has no arguments or keywords.

Command Default

EOT does not consider the carrier-delay timer configured on an interface when tracking the status of the interface.

Command Modes

Tracking configuration (config-track)

Command History

Release

Modification

12.4(9)T

This command was introduced.

15.3(3)M

This command was integrated into Cisco IOS Release 15.3(3)M.

Cisco IOS XE 3.3SE

This command was implemented in Cisco IOS XE Release 3.3SE.

Usage Guidelines

If a link fails, by default there is a two-second timer that must expire before an interface and the associated routes are declared down. If a link goes down and comes back up before the carrier delay timer expires, the down state is effectively filtered, and the rest of the software on the switch is not aware that a link-down event occurred. You can configure the carrier-delay seconds command in interface configuration mode to extend the timer up to 60 seconds.

When Enhanced Object Tracking (EOT) is configured on an interface, the tracking may detect the interface is down before a configured carrier-delay timer has expired. This is because EOT looks at the interface state and does not consider the carrier-delay timer.

Examples

The following example shows how to configure the tracking module to wait for the interface carrier-delay timer to expire before notifying clients of a state change:

Router(config)# track 101 interface ethernet1/0 line-protocol
Router(config-track)# carrier-delay

The amount of available CPU resources on a router is dependent upon variables such as traffic load and how other protocols are configured and run. The ability to use 1000 tracked objects is dependent upon the available CPU. Testing should be conducted on site to ensure that the service works under the specific site traffic conditions.

EEM is a distributed, scalable, and customized approach to event detection and recovery offered directly in a Cisco IOS device. EEM offers the ability to monitor events and take informational or corrective action when the monitored events occur or when a threshold is reached. An EEM policy is an entity that defines an event and the actions to be taken when that event occurs.

Usage Guidelines

This command is available to all tracked objects.

If you specify, for example, delay up 10 down 30, then if the object state changes from down to up, clients tracking that object are notified after 10 seconds. If the object state changes from up to down, then clients tracking that object are notified after 30 seconds.

Examples

In the following example, the tracking process is tracking the IP-route threshold metric. The delay period to communicate the tracked object state changing to down is set to 30 seconds.

Router(config)# track 1 ip route 10.22.0.0/16 metric threshold
Router(config-track)# threshold metric up 16 down 20
Router(config-track)# delay down 30
