Administrator Guide

● For a port channel interface, enter the keywords port-channel then a number.
● For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
For an IPv4 interface, a routing object only tracks the UP/DOWN status of the specified IPv4 interface (the track
interface ip-routing command).
● The status of an IPv4 interface is UP only if the Layer 2 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 2 status goes down or the IP address is removed from
the routing table. For a Layer 3 VLAN, all VLAN ports must be down.
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 or the IPv6 address is removed from
the routing table. For a Layer 3 VLAN, all VLAN ports must be down.
To remove object tracking on a Layer 3 IPv4 or 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 65535.
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
Example of configuring object tracking for an IPv4 interface.
