Table 318: Diffserv Policy Configuration Fields (continued)
Field
Description
Police Simple
Select this option to enable the simple traffic policing style for the policy-class.
The simple form of the police attribute uses a single data rate and burst size,
resulting in two outcomes (conform and violate). After you select this option,
configure the following policing criteria:
•
Color Mode – The type of color policing used in DiffServ traffic conditioning.
•
Color Conform Class – For color-aware policing, packets in this class are
metered against both the committed information rate (CIR) and the peak
information rate (PIR). The class definition used for policing color awareness
is only allowed to contain a single, non-excluded class match condition
identifying one of the supported comparison fields: CoS, IP DSCP, IP
Precedence, or Secondary COS.
•
Committed Rate (Kbps) – The maximum allowed arrival rate of incoming
packets for this class.
•
Committed Burst Size (Kbytes) – The amount of conforming traffic allowed
in a burst.
•
Conform Action – The action taken on packets that are considered
conforming (below the police rate).
•
Violate Action – The action taken on packets that are considered non-
conforming (above the police rate).
Police Single Rate
Select this option to enable the single-rate traffic policing style for the policy-
class. The single-rate form of the police attribute uses a single data rate and two
burst sizes, resulting in three outcomes (conform, exceed, and violate). After you
select this option, configure the following policing criteria:
•
Color Mode – The type of color policing used in DiffServ traffic conditioning.
•
Color Conform Class – For color-aware policing, packets are metered against
the committed information rate (CIR) and the peak information rate (PIR).
The class definition used for policing color awareness is only allowed to
contain a single, non-excluded class match condition identifying one of the
supported comparison fields: CoS, IP DSCP, IP Precedence, or Secondary
COS. This field is available only if one or more classes that meets the color-
awareness criteria exist.
•
Color Exceed Class – For color-aware policing, packets are metered against
the PIR only.
•
Committed Rate (Kbps) – The maximum allowed arrival rate of incoming
packets for this class.
•
Committed Burst Size (Kbytes) – The amount of conforming traffic allowed
in a burst.
•
Excess Burst Size (Kbytes) – The amount of conforming traffic allowed to
accumulate beyond the Committed Burst Size (Kbytes) value during longer-
than-normal idle times. This value allows for occasional bursting.
•
Conform Action – The action taken on packets that are considered
conforming (below the police rate).
•
Exceed Action – The action taken on packets that are considered to exceed
the committed burst size but are within the excessive burst size.
•
Violate Action – The action taken on packets that are considered non-
conforming (above the police rate).
