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.
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.
Configure the UP and DOWN thresholds for each tracked route with the
threshold metric command. The default UP threshold is 254; the default
DOWN threshold is 255. The notification of a change in the state of a tracked
object is sent when a metric value crosses a configured threshold.
