Chapter 69 Configuring Enhanced Object Tracking
Configuring Enhanced Object Tracking Features
Configuring a Tracked List with a Percentage Threshold
To track by percentage threshold, configure a tracked list of objects, specify that a percentage will be
used as the threshold, and specify a percentage for all objects in the list. The state of the list is determined
by comparing the assigned percentage of each object to the list.
You cannot use the Boolean “NOT” operator in a percentage threshold list.
To configure a tracked list of objects by using a percentage threshold, perform this task:
Use the no track track-number global configuration command to delete the tracked list.
This example configures tracked list 4 with three objects and a specified percentages to measure the state
of the list:
Switch(config)# track 4 list threshold percentage
Switch(config-track)# object 1
Switch(config-track)# object 2
Switch(config-track)# object 3
Switch(config-track)# threshold percentage up 51 down 10
Switch(config-track)# exit
Command Purpose
Step 1
configure terminal
Enters global configuration mode.
Step 2
track track-number list
threshold percentage
Configures a tracked list object and enter tracking configuration mode. The
track-number can be from 1 to 500.
• threshold—Specify the state of the tracked list based on a threshold.
• percentage—Specify that the threshold is based on percentage.
Step 3
object object-number
Specifies the object to be tracked. The range is from 1 to 500.
Note An object must exist before you can add it to a tracked list.
Step 4
threshold percentage {up number
| [down number]}
Specifies the threshold percentage.
• up number—The valid range is from 1 to 100.
• down number]—(Optional) The range depends on the number selected
for the up number. If you configure the up number as 25, the range
shown for the down number is 0 to 24.
Step 5
delay {up seconds [down seconds]
| [up seconds] down seconds}
(Optional) Specifies a period of time in seconds to delay communicating
state changes of a tracked object. The range is from 1 to 180 seconds.
Step 6
end
Returns to privileged EXEC mode.
Step 7
show track object-number
Verifies that the specified objects are being tracked.
Step 8
copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
