Information About Ingress Policing
Policing allows you to monitor the data rates for a particular class of traffic. When the data rate exceeds user-configured values, the switch drops packets immediately. Because policing does not buffer the traffic; transmission delays are not affected. When traffic exceeds the data rate on a specific class, the switch drops the packets.
You can define single-rate and two-color Ingress Policing.
Single-rate Ingress Policing monitors the committed information rate (CIR) of traffic.
Note |
The committed information rate (CIR) is a value specified as a bit rate from 1 to 80000000000 or a percentage of the link rate. |
In addition, Ingress Policing can monitor associated burst sizes of the packets. Two colors, or conditions, are determined by Ingress Policing for each packet depending on the data rate parameters that you supply.
You can configure only one action for each condition. For example, you might police for traffic in a class to conform to the data rate of 256000 bits per second with up to 200 millisecond bursts.
Color-aware Ingress Policing assumes that traffic has been previously marked with a color.
