threshold metric {[up number] [down number]} 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. The defult DOWN threshold is 255. The routing state is DOWN if the scaled route metric is greater than or equal to the DOWN threshold. 6 (Optional) Display the tracking configuration. EXEC Privilege mode show track object-id Example of IPv4 and IPv6 Tracking Metric Thresholds The following example configures object tracking on the metric threshold of an IPv4 route: Dell(conf)#track 6 ip route 2.1.1.0/24 metric threshold Dell(conf-track-6)#delay down 20 Dell(conf-track-6)#delay up 20 Dell(conf-track-6)#description track ip route metric Dell(conf-track-6)#threshold metric down 40 Dell(conf-track-6)#threshold metric up 40 Dell(conf-track-6)#exit Dell(conf)#track 10 ip route 3.1.1.0/24 metric threshold vrf vrf1 Example of IPv4 and IPv6 Tracking Metric Thresholds The following example configures object tracking on the metric threshold of an IPv6 route: Dell(conf)#track 8 ipv6 route 2::/64 metric threshold Dell(conf-track-8)#threshold metric up 30 Dell(conf-track-8)#threshold metric down 40 Displaying Tracked Objects To display the currently configured objects used to track Layer 2 and Layer 3 interfaces, and IPv4 and IPv6 routes, use the following show commands. To display the configuration and status of currently tracked Layer 2 or Layer 3 interfaces, IPv4 or IPv6 routes, or a VRF instance, use the show track command. You can also display the currently configured per-protocol resolution values used to scale route metrics when tracking metric thresholds. • Display the configuration and status of currently tracked Layer 2 or Layer 3 interfaces, IPv4 or IPv6 routes, and a VRF instance. show track [object-id [brief] | interface [brief] [vrf vrf-name] | ip route [brief] [vrf vrfname] | resolution | vrf vrf-name [brief] | brief] • Use the show running-config track command to display the tracking configuration of a specified object or all objects that are currently configured on the router. show running-config track [object-id] Examples of Viewing Tracked Objects Dell#show track Track 1 IP route 23.0.0.0/8 reachability Reachability is Down (route not in route table) 2 changes, last change 00:16:08 Tracked by: Track 2 IPv6 route 2040::/64 metric threshold Metric threshold is Up (STATIC/0/0) 5 changes, last change 00:02:16 Metric threshold down 255 up 254 604 Object Tracking
