Aggregate Policer Settings on ESW2-350G Switches

Objective

The switch uses policies to support per-flow QoS when it is in QoS advanced mode. An aggregate policer applies QoS to multiple class maps, therefore having one or more flows. It supports class maps from different policies and applies QoS to each of its flows in aggregation, hence the name Aggregate Policer. 

This article explains how to set up an aggregate policer on a ESW2-350G Switches.

Note: QoS must be in advanced mode. For more information refer to the article entitled Quality of Service (QoS) Properties on ESW2-350G Switches.

Applicable Devices

• ESW2-350G
• ESW2-350G-DC

Aggregate Policer

Step 1. Log in to the web configuration utility to choose Quality of Service > QoS Advanced Mode > Aggregate Policer. The Aggregate Policer page opens:

Step 2. Click Add to add a policy. The Add Aggregate Policer window appears.

Step 3. At the Aggregate Policer Name field, enter a name for the Aggregate Policer.

Step 4. At the Ingress Committed Information Rate (CIR) field, enter the CIR value. It specifies the amount of bandwidth on a frame relay service.

Step 5. At the Ingress Committed Burst Size (CBS) field, enter the maximum burst size (even if it goes beyond the CIR) in bytes. Committed burst size is the amount of data that a network accepts in a given committed rate measurement interval (Tc). Tc is defined as ratio of CBS to CIR.

Step 6. Click the appropriate radio button in the Exceed Action field to define what action has to be taken when the packets exceed the CIR limit. The possible values are as follows:

• Forward — Forwards the packets which exceed the CIR limit.

• Drop — Drops the packets which exceed the CIR limit.

• Out of Profile DSCP — This replaces the old DSCP values with the new DSCP values based on the Out of Profile DSCP Mapping table for the packets which exceed the CIR limit.

Note: For more information on the Out of Profile DSCP Mapping table, refer to the article entitled Configuration of Out of Profile DSCP Mapping on ESW2-350G Switches.

Step 7. Click Apply to save the changes. 

Step 8. (Optional) To edit the aggregate policer, check the particular aggregate policer and click Edit and follow Steps 3-7.

Step 9. (Optional) To delete the aggregate policer, check the particular aggregate policer and click Delete.
