Configuring Enhanced Object Tracking Features
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
r
eachability 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 tr

Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
track object-number rtr
operation-number state
Enter tracking configuration mode to track the state of an IP SLAs operation.
• The object-number range is from 1 to 500.
• The operation-number range is from 1 to 2147483647.
Step 3
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.
Step 4
exit Return to global configuration mode.
Step 5
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.
Step 6
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.
Step 7
end Return to privileged EXEC mode.
Step 8
show track object-number Display tracking information to verify the configuration.
Step 9
