• Action — Defines the action attached to the rule. The possible field values are:
– Trust CoS-DSCP — Enables Trust Mode for the class. This command is used to distinguish
the QoS trust behavior for given traffic. When a given type is trusted, the QoS mechanism
maps a packet to a queue using the received or default value and the relevant map, as
defined on the QoS Settings. By designating trust, it is possible to trust only incoming traffic
with certain DSCP values.
– Set — Manually configures the Trust.
• Police — Enables Policer functionality.
• Type — Policer type for the policy. Possible values are:
– Aggregate — Configures the class to use a configured aggregate policer selected from the
drop-down menu. An aggregate policer is defined if the policer is shared with multiple
classes. Traffic from two different ports can be configured for policing purposes. An
aggregate policer can be applied to multiple classes in the same policy map, but cannot be
used across different policy maps.
– Single — Configures the class to use manually configured information rates and exceed
actions.
• Aggregate Policer — Specifies the Aggregate Policer Name
• Ingress Committed Information Rate (CIR) — Defines the CIR in bits per second. This field is
only relevant when the Police value is Single.
• Ingress Committed Burst Size (CBS) — Defines the CBS in bytes per second. This field is only
relevant when the Police value is Single.
• Exceed Action — Action assigned to incoming packets exceeding the CIR. This field is only
relevant when the Police value is Single. Possible values are:
– Drop — Drops packets exceeding the defined CIR value.
– Remark DSCP —Remarks packet’s DSCP values exceeding the defined CIR value.
– None —Forwards packets exceeding the defined CIR value.
