Configuring Enhanced Object Tracking
Configuring Enhanced Object Tracking Features
Configuring Other Tracking Characteristics
You can also use the enhanced object tracking for tracking other characteristics.

You can track the reachability of an IP route by using the track ip route reachability global configuration command .

You can use the track ip route metric threshold global configuration command to determine if a route is above or
below threshold.

You can use the track resolution global configuration command to change the metric resolution default values for
routing protocols.

You can use the track timer tracking configuration command to configure the tracking process to periodically poll
tracked objects.
Use the show track privileged EXEC command to verify enhanced object tracking configuration.

Configuring IP SLAs Object Tracking
Cisco IOS IP Service Level Agreements (IP SLAs) is a network performance measurement and diagnostics tool that uses
active monitoring by generating traffic to measure network performance. Cisco IP SLAs operations collects real-time
metrics that you can use for network troubleshooting, design, and analysis.
For IP SLAs command information see the Cisco IOS IP SLAs Command Reference Guide, Release 12.4T at this URL:
http://www.cisco.com/en/US/docs/ios/ipsla/configuration/guide/12_4t/sla_12_4t_book.html
Object tracking of IP SLAs operations allows clients to track the output from IP SLAs objects and use this information to
trigger an action. Every IP SLAs operation maintains an SNMP operation return-code value, such as
OK or OverThreshold ,
that can be interpreted by the tracking process. You can track two aspects of IP SLAs operation: state and reachability.
For state, if the return code is OK, the track state is up; if the return code is not OK, the track state is down. For
reachability, if the return code is OK or OverThreshold, reachability is up; if not OK, reachability is down.
6. standby [ group-number ] track
object-number [ decrement
[ priority-decrement ]]
Configure HSRP to track an object and change the hot standby priority
based on the state of the object.

(Optional) group-number —Enter the group number to which the tracking
applies.

object-number —Enter a number representing the object to be tracked.
The range is from 1 to 500; the default is 1.

(Optional) decrement priority-decrement —Specify the amount by which
the hot standby priority for the router is decremented (or incremented)
when the tracked object goes down (or comes back up). The range is
from 1 to 255; the default is 10.
7. end Return to privileged EXEC mode.
8. show standby Verify the standby router IP address and tracking states.
9. copy running-config
startup-config (Optional) Save your entries in the configuration file.
