Class maps configuration parameters

A Class Map is used to classify stream of traffic.
The following section describes the parameters for configuration of QoS class maps located at

Variable definitions
The following table describes the variables and values for configuring class maps.
Variable
Class Map ID
Policy Map ID
Source IP Address
Source Subnet Mask
Destination IP Address
NN47928-500 NN47928-500
Value
Type the unique ID of the policer.
Select the supported police type. The only supported police algorithm is
TRTCM.
TRTCM indicates Two Rates Three Color Marker. This meters an IP
packet stream and marks the packets based on two rates: Peak
Information Rate (PIR) and Committed Information Rate (CIR). The
associated threshold sizes are green, amber, or red. A packet is marked
red if it exceeds PIR. It is marked amber if it exceeds CIR. It is marked
green if it does not exceed CIR.
The marking is based on Committed Information Rate (CIR) and two
associated burst sizes - Committed Burst Size (CBS) and Peak Burst Size
(PBS). A packet is marked green if it does not exceed CBS and amber if it
exceeds CBS but not PBS. Otherwise, it is marked red.
Type the PIR key value in bytes per second.
The default value is 3250000.
Type the CIR key value in bytes per second.
The default value is 3000000.
Type the PBS key value in bytes per second.
The default value is 15000.
Type the CBS key value in bytes per second.
The default value is 10000.
