Object Tracking
Table 37-2. Command Example Description: show track brief
ResID
Number of the tracked object
Resource
Type of tracked object
Parameter
Detailed description of the tracked object
State
Up or Down state of the tracked object
Last Change
Time since the last change in the state of the tracked object
Configure the metric threshold used to determine the UP and/or DOWN state of a tracked IPv4 or IPv6
route.
threshold metric {up number | down number}
To return to the default setting, enter no threshold metric {up number | down number}.
object-id
Enter the ID number of the tracked object. Range: 1 to 65535.
up number
Enter a number for the UP threshold to be applied to the scaled metric of an IPv4 or
IPv6 route.
Default UP threshold: 254. The routing state is UP if the scaled route metric is less
than or equal to the UP threshold.
down number
Enter a number for the DOWN threshold to be applied to the scaled metric of an IPv4
or IPv6 route
Default DOWN threshold: 255. The routing state is DOWN if the scaled route metric
is greater than or equal to the DOWN threshold.
None
OBJECT TRACKING (conf_track_object-id)
Version 8.4.1.0
Introduced
track ip route
Configure object tracking on the threshold of an IPv4 route metric.
metric threshold
track resolution ip
Configure the protocol-specific resolution value used to scale an IPv4 route metric.
route
Use this command to configure the UP and/or DOWN threshold for the scaled metric of a tracked IPv4
or IPv6 route.
The UP/DOWN state of a tracked route is determined by the threshold for the current value of the route
metric in the routing table. To provide a common tracking interface for different clients, route metrics
are scaled in the range 0 to 255, where 0 is connected and 255 is inaccessible. The scaled metric value
communicated to a client always considers a lower value to have priority over a higher value.
The resulting scaled value is compared against the configured threshold values to determine the state of
a tracked route as follows:
