Defining Aggregate Policers
An aggregate policer applies the QoS to one or more class maps, therefore one or
more flows. An aggregation policer can support class maps from different policies
and applies the QoS to all its flow(s) in aggregation regardless of policies and
ports.
NOTE The device supports aggregate policers and single policers only when operating
in Layer 2 mode in devices that support a separate Layer 2 system mode.
To define an aggregate policer:
STEP 1 Click Quality of Service > QoS Advanced Mode > Aggregate Policer.
This page displays the existing aggregate policers.
STEP 2 Click Add.
STEP 3 Enter the parameters.
• Aggregate Policer Name—Enter the name of the Aggregate Policer.
• Ingress Committed Information Rate (CIR)—Enter the maximum
bandwidth allowed in bits per second. See the description of this in the
Bandwidth page.
• Ingress Committed Burst Size (CBS)—Enter the maximum burst size (even
if it goes beyond the CIR) in bytes. See the description of this in the
Bandwidth page.
• Exceed Action—Select the action to be performed on incoming packets
that exceed the CIR. Possible values are:
- Forward—Packets exceeding the defined CIR value are forwarded.
- Drop—Packets exceeding the defined CIR value are dropped.
- Out of Profile DSCP—The DSCP values of packets exceeding the
defined CIR value are remapped to a value based on the Out Of Profile
DSCP Mapping Table.
STEP 4 Click Apply. The Running Configuration file is updated.
