Owners Manual

● Port channel: Enter port-channel number, where valid port-channel numbers are from 1 to 128:
● SONET: Enter sonet slot/port.
● VLAN: Enter vlan vlan-id, where valid VLAN IDs are from 1 to 4094
A line-protocol object only tracks the link-level (UP/DOWN) status of a specified interface. When the link-level status goes
down, the tracked object status is DOWN; if the link-level status is up, the tracked object status is UP.
To remove object tracking on a Layer 2 interface, use the no track object-id command.
To configure object tracking on the status of a Layer 2 interface, use the following commands.
1. Configure object tracking on the line-protocol state of a Layer 2 interface.
CONFIGURATION mode
track object-id interface interface line-protocol
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

Tracking a Layer 3 Interface
You can create an object that tracks the routing status of an IPv4 or IPv6 Layer 3 interface.
You can track the routing status of any of the following Layer 3 interfaces:
●
For a 1-Gigabit Ethernet: enter gigabitethernet slot/port in the track interface interface command (see
Step 1).
● For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport information.
● 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.
