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 is
255 . The routing state is DOWN if the scaled
route metric is greater than or equal to the DOWN threshold.
Defaults None
Command Modes OBJECT TRACKING (conf_track _object-id )

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.
The resulting scaled value is compared against the configured threshold values to determine the state of a tracked
route as follows:
• If the scaled metric for a route entry is less than or equal to the UP threshold, the state of a route is UP.
• If the scaled metric for a route is greater than or equal to the DOWN threshold or the route is not entered in
the routing table, the state of a route is DOWN.
