This read-create DisplayString holds the human-readable name assigned to a QoS Policer definition. An admin names policers meaningfully so that class maps and interfaces referencing rate-limiting can be understood at a glance, such as 'GUEST-RATE-LIMIT,' rather than tracking numeric pointers alone. For example, an admin creating a policer to cap guest-network throughput would name it 'GUEST-1MBPS' so its purpose is obvious when reviewing QoS configuration later.
