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 more information about Cisco IP SLAs on the switch, see
SLAs Operations."

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.
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:
Command
Step 1
configure terminal
Step 2 track object-number rtr
operation-number state
Step 3
delay {up seconds [down seconds] |
[up seconds] down seconds}
Step 4
exit
Step 5 track object-number rtr
operation-number reachability
Step 6
delay {up seconds [down seconds] |
[up seconds] down seconds}
Step 7
end
Step 8
show track object-number
Step 9 copy running-config startup-config (Optional) Save your entries in the configuration file.
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

•
(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.
Return to global configuration mode.
Enter tracking configuration mode to track the reachability of an IP SLAs IP
host.

•
(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.
Return to privileged EXEC mode.
Display tracking information to verify the configuration.
