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 will apply the QoS to all its flow(s) in aggregation regardless of policies and ports.

NOTE     The switch supports aggregate policers and single policers only when operating in Layer 2 mode.

To define an aggregate policer:

  1. Click Quality of Service > QoS Advanced Mode > Aggregate Policer (Layer 2). The Aggregate Policer (Layer 2) page opens.
  2. This page displays the existing aggregate policers.

  3. Click Add. The Add Aggregate Policer page opens.
  4. 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 description in the Bandwidth page.
    • Ingress Committed Burst Size (CBS)--Enter the maximum burst size (even if it goes beyond the CIR) in bytes. See description 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.
  5. Click Apply. The Running Configuration file is updated.
