Labels

Labels are tags that help you group and organize fabric items according to specific criteria. You can assign the labels to various fabric items, such as fabric intents, workload VPN intents, maintenance intents, or to objects within each of these intents. For instance, within a fabric intent, you can label specific groupings of nodes. Within a workload intent, you can label specific groupings of subnets and sub-interfaces.

Labels are a powerful tool for identifying a group of objects that can then be subject to collective actions. For example, as part of a maintenance intent, you can create a label and apply it to a group of items that will be subject to a software upgrade. Then, you can apply the upgrade to all of the nodes with that label as a single action, instead of upgrading each node individually. See Labeling objects for maintenance for a detailed procedure.

Labels can also be used for informational purposes. You can label specific fabric elements based on criteria such as their physical location. For instance, you can create a label to identify nodes located in a specific data center (DC), then apply this label to nodes physically located in that DC.
