This is the unique name (1-32 octets) that identifies a DPI policy entry and serves as the table's index; it is assigned at creation and cannot be changed afterward. Admins use this name to reference the policy when binding it to subscribers or interfaces, and because it's immutable once set, careful naming up front avoids having to recreate the policy later. For example, an admin might create a policy named 'p2p-limit' to later apply consistent DPI behavior across multiple BRAS configurations.
