Configuring A Tracked List With A Percentage Threshold - Cisco Catalyst 4500 Series Software Configuration Manual

Chapter 69 Configuring Enhanced Object Tracking

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:
Command
Step 1
configure terminal
Step 2
track track-number list
threshold percentage
Step 3
object object-number
Step 4
threshold percentage {up number
| [down number]}
Step 5
delay {up seconds [down seconds]
| [up seconds] down seconds}
Step 6
end
Step 7
show track object-number
Step 8
copy running-config
startup-config
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
Purpose
Enters global configuration mode.
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.
•
Specifies the object to be tracked. The range is from 1 to 500.
Note
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.
(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.
Returns to privileged EXEC mode.
Verifies that the specified objects are being tracked.
(Optional) Saves your entries in the configuration file.

An object must exist before you can add it to a tracked list.
