Dell S3048-ON Configuration Manual page 533

For an IPv6 interface, a routing object only tracks the UP/DOWN status of the specified IPv6 interface (the track interface ipv6-
routing command).
• The status of an IPv6 interface is UP only if the Layer 2 status of the interface is UP and the interface has a valid IPv6 address.
• The Layer 3 status of an IPv6 interface goes DOWN when its Layer 2 status goes down (for a Layer 3 VLAN, all VLAN ports must be
down) or the IPv6 address is removed from the routing table.
To remove object tracking on a Layer 3 IPv4/IPv6 interface, use the no track object-id command.
To configure object tracking on the routing status of a Layer 3 interface, use the following commands.
1 Configure object tracking on the routing status of an IPv4 or IPv6 interface.
CONFIGURATION mode
track object-id interface interface {ip routing | ipv6 routing}
Valid object IDs are from 1 to 500.
2 (Optional) Configure the time delay used before communicating a change in the status of a tracked interface.
OBJECT TRACKING mode
delay {[up seconds] [down seconds]}
Valid delay times are from 0 to 180 seconds.
The default is 0.
3 (Optional) Identify the tracked object with a text description.
OBJECT TRACKING mode
description text
The text string can be up to 80 characters.
4 (Optional) Display the tracking configuration and the tracked object's status.
EXEC Privilege mode
show track object-id
Examples of Configuring Object Tracking for an IPv4 or IPv6 Interface
Examples of Configuring Object Tracking for an IPv4 or IPv6 Interface
The following is an example of configuring object tracking for an IPv4 interface:
Dell(conf)#track 101 interface gigabitethernet 1/2 ip routing
Dell(conf-track-101)#delay up 20
Dell(conf-track-101)#description NYC metro
Dell(conf-track-101)#end
Dell#show track 101
Track 101
Interface GigabitEthernet 7/2 ip routing
Description: NYC metro
The following is an example of configuring object tracking for an IPv6 interface:
Dell(conf)#track 103 interface gigabitethernet 1/11 ipv6
routing
Dell(conf-track-103)#description Austin access point
Dell(conf-track-103)#end
Dell#show track 103
