Description
Apply a policer to an interface. Configure policer rate limits and actions. The traffic to the Routing Engine is controlled by applying the policer on ARP. This prevents network congestion caused by broadcast storms.
A policer applies two types of rate limits on traffic:
Bandwidth—The number of bits per second permitted, on average
Maximum burst size—The maximum size permitted for bursts of data that exceed the given bandwidth limit
