Administrator Guide

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.
The tracking process uses a protocol-specific resolution value to convert the actual metric in the routing table to a
scaled metric in the range 0 to 255. You can configure the resolution value used to scale route metrics for
supported protocols with the track resolution ip route and track resolution ipv6 route
commands.

Usage Information Use this command to create an object that tracks the routing state of an IPv4 Layer 3 interface:
• The status of the IPv4 interface is UP only if the Layer 3 status of the interface is UP and the interface has a
valid IP address.
• The Layer 3 status of an IPv4 interface goes DOWN when its Layer 3 status goes down (for a Layer 3 VLAN,
all VLAN ports must be down) or the IP address is removed from the routing table.
