Commands
● show running-config track – display configuration information about tracked objects.
● track interface ip routing – configure object tracking on the routing status of an IPv4 Layer 3
interface.
● track interface line-protocol – configure object tracking on the line-protocol state of a Layer 2
interface.
● track ip route metric threshold – configure object tracking on the threshold of an IPv4 route metric.
● track ip route reachability – configure object tracking on the reachability of an IPv4 route.
threshold metric
Configure the metric threshold used to determine the UP and/or DOWN state of a tracked IPv4 or IPv6 route.
Syntax
threshold metric {up number | down number}
To return to the default setting, use the no threshold metric {up number | down number}
command.
Parameters
up number Enter a number for the UP threshold to be applied to the scaled metric of an IPv4
or IPv6 route. The default UP threshold is 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. The default DOWN threshold is255. The routing state is DOWN
if the scaled route metric is greater than or equal to the DOWN threshold.
Defaults None

Usage
Information
Use this command to configure the UP and/or DOWN threshold for the scaled metric of a tracked IPv4 or
IPv6 route.
Determine the UP/DOWN state of a tracked route 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.
