Which CoPP feature can you configure after applying the control-plane command?

Line card interfaces are physical components of a switch and are not a feature directly configurable within the CoPP `control-plane` mode for traffic classification.

Address filters are typically components of access control lists (ACLs) used for traffic matching, but 'address filters' itself is not a specific CoPP feature configured under `control-plane` in the same way aggregates are.

The `control-plane` configuration mode allows for the definition of aggregates, which group multiple types of control plane traffic into a single class for policy application, such as rate-limiting. This helps in efficiently managing and protecting the control plane from excessive traffic.

Drop policies are actions applied *within* a CoPP policy (e.g., `police exceed drop`), not a top-level feature directly configured after the `control-plane` command itself.
