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, desi gn, and
analysis.
For more information about Cisco IP SLAs on the switch, see Chapter41, “ Co nfiguring C isco IO S IP
SLAs Operations.” For IP SLAs command information see the Cisco IOS IP SLAs Command Reference,
Release 12.4T at this URL:

Object tracking of IP SLAs operations allows clients to track the ou tput f rom I P SL A s ob ject s 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.
Beginning in privileged EXEC mode, follow these steps to track the state of an IP SLAs operation or the
reachability of an IP SLAs IP host:
This example shows how to configure and display IP SLAs state tracking:
Switch(config)# track 2 200 state
Switch(config)# end
Switch# show track 2
Track 2
Response Time Reporter 1 state
State is Down
1 change, last change 00:00:47
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 track object-number rtr
operation-number state Enter tracking configuration mode to track the state of an IP SLAs operati on.
•The object-number range is from 1 to 500.
•The operation-number range is from 1 to 2147483647.
Step3 delay {up seconds [down seconds] |
[up seconds] down seconds}(Optional) Specify a period of time in seconds to delay communicating state
changes of a tracked object. The range is from 1 to 180 seconds.
Step4 exit Return to global configuration mode.
Step5 track object-number rtr
operation-number reachability Enter tracking configuration mode to track the reachability of an IP SLAs IP
host.
•The object-number range is from 1 to 500.
•The operation-number range is from 1 to 2147483647.
Step6 delay {up seconds [down seconds] |
[up seconds] down seconds}(Optional) Specify a period of time in seconds to delay communicating state
changes of a tracked object. The range is from 1 to 180 seconds.
Step7 end Return to privileged EXEC mode.
Step8 show track object-number Display tracking information to verify the configuration.
Step9 copy running-config startup-config (Optional) Save your entries in the configuration file.
