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 considered to be conforming (below the police rate).
•
Violate Action
The action taken on packets considered to be 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 considered to be 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 considered to be non-conforming (above the police rate).
Police Two Rate
Select this option to enable the two-rate traffic policing style for the policy-class. The two-rate form of
the police attribute uses two data rates and two burst sizes. Only the smaller of the two data rates is
intended to be guaranteed. 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.
•
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.
•
Peak Rate (Kbps)
The maximum information rate for the arrival of incoming packets for this class.
•
Excess Burst Size (Kbytes)
The maximum size of the packet burst that can be accepted to
maintain the Peak Rate (Kbps).
•
Conform Action
The action taken on packets considered to be 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 considered to be non-conforming (above police rate).
Redirect Interface
Select this option to force a classified traffic stream to the specified egress port (physical port or LAG).
Use the Interface field to select the interface to which traffic is redirected.
After you select the policy to configure from the Policy menu, use the buttons to perform the following tasks:
•
To add a class to the policy, click Add Class.
•
To add attributes to a policy or to change the policy attributes, select the policy with the attributes to
configure and click Add Attribute.
•
To remove the most recently associated class from the selected policy, click Remove Last Class.
•
Click Refresh to refresh the page with the most current data from the switch.
To retain the changes across the switch’s next power cycle, click System
