The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Chapter: T Commands
T Commands
This chapter describes the Cisco NX-OS Virtual Router Redundancy Protocol (VRRP) commands that begin with T.
track (VRRP)
To modify the priority for a virtual router based on a tracked object, use the track command. To disable priority tracking for a virtual router, use the no form of this command.
track object-number [ decrement value ]
no track object-number [ decrement value ]
Syntax Description
Number for a configured tracked object. The range is from 1 to 500. |
|
(Optional) Decrements the VRRP priority if the tracked object is down. The range is from 1 to 254. |

Usage Guidelines
Use the track (VRRP) command to change the priority of the virtual router based on the state of a configured tracked object. Use the track command to configure the tracked object. When the tracked object is down, the priority reverts to the priority value for the virtual router. When the tracked object is up, the priority of the virtual router is restored to the original value.
Examples
This example shows how to enable object tracking for a virtual router:

track interface (VRRP)
To track the priority for a virtual router based on an interface, use the track interface command. To disable priority tracking for a virtual router, use the no form of this command.
track interface { ethernet slot /[ QSFP-module /] port | port-channel number [. sub_if_number ]} priority value
no track interface { ethernet slot /[ QSFP-module /] port | port-channel number [. sub_if_number ]} priority value

Usage Guidelines
Use the track command to change the priority of the virtual router based on the state of another interface in the switch. When the tracked interface is down, the priority reverts to the priority value for the virtual router. When the tracked interface is up, the priority of the virtual router is restored to the interface state tracking value.
Note
Interface state tracking will not be operational unless you enable preemption on the interface.
