threshold metric
Configure the metric threshold used to determine the UP and/or DOWN state of a tracked IPv4 or IPv6
route.
C9000 Series
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
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:
