Importing Custom Labels
You can upload or manually assign custom labels to associate user-defined data with specific hosts. This user-defined data is used to annotate associated flows and inventory.
There are limits on the number of IPv4/IPv6 addresses/subnets that can be labeled across all root scopes, regardless of label source (whether manually entered or uploaded, ingested using connectors or external orchestrators, and so on) For details, see Label Limits .
