Bandwidth Policer

A bandwidth policer is a method of characterizing service frames for the purpose of rate
enforcement. A bandwidth policer can be applied in one of the following ways:
• Ingress bandwidth policer per ingress UNI
• Ingress bandwidth policer per EVC
• Ingress bandwidth policer per custom
In typical applications, the bandwidth available on the EVC is less than the bandwidth
available at the UNI port. The bandwidth bottleneck is typically only in the UNI‐to‐MEN
direction; therefore, all bandwidth policers are applied only for traffic conducted in the UNI‐
to‐MEN direction. Policers are not applied to the traffic conducted in the MEN‐to‐UNI
direction.

Bandwidth Policer Attributes

The attributes of a bandwidth policer are described in the following paragraphs.

Name

This attribute is an arbitrary string that is used to identify the policer. The value must be
unique across all policers defined in the product, and is intended for management and control
purposes. The value is not carried in any field in the Ethernet frame.

Configuration Status

This attribute is a read‐only status identifier of the policer. The policer can be administratively
enabled, but it can not be in functional state if it is not fully configured or if there is a conflict.
Table F‐11 lists the possible values.
Possible Value
Running
Disabled
Duplicate policer
Invalid rate(s)
No Mode
Unknown UNI
Unknown EVC
Unknown EVC‐map

Table F-11. Policer Status Values

Definition
The policer is running and applying ingress a bandwidth profile
to any matching EVC maps.
The administrative state of the policer is provisioned as Disabled.
An enabled policer with equal precedence and equal value exists.
Refer to Rule 4 on page F‐2.
The values for CIR and/or EIR conflict in relation to the rate cou‐
pling value.
The mode attribute of the policer is not set.
The mode is per UNI and the UNI can not be found.
The mode per EVC and the EVC can not be found.
The mode per Custom and the EVC map can not be found.
