QoS will prioritize the network traffic based on the criteria specified. It improves the performance of the network by classifying the incoming traffic based on the attributes it carries and then by assigning network resources to each class of traffic. A policer allows you to control the maximum rate of traffic sent or received on an interface, and to partition a network into multiple priority levels.
This article explains the configuration of policer statistics in QoS on SFE/SGE managed devices.
Note: Before configuring Policer Statistics you need to configure a class map name. To do so, refer to the article Configuration of Class Mapping in QoS Advanced Mode on SFE/SGE Managed Device. To create policy name, refer to the article Quality of Service (QoS) Policy Profile Modification on SFE/SGE Managed Switches.
• SFE/SGE Managed Devices
• v3.0.2.0
Step 1. Log in to the web configuration utility, choose Quality of Service > QoS Statistics > Policer Statistics. The Policer Statistics page opens up:
The Policer Statistics page contains the following fields:
• Interface — Shows the interface which is configured to the current policer statistics.
• Policy — Shows the policy which is configured to the current policer statistics.
• Class Map — Shows the class map with the current statistics.
• In-Profile Bytes — Shows the total number of in-profile bytes received at the interface.
• Out-of-Profile Bytes — Shows the total number of out-of-profile bytes received at the interface.
• Clear Counters — This allows you to clear all statistics counters.
Step 2. Click the Add button. The Add Policer Statistics page opens up:
Step 3. Select either Port or LAG interface for which you want to add policer statistics.
Step 4. Choose the policy name from the drop-down list. A policy contains a series of actions that you want to apply on a set of classified inbound traffic.
Step 5. Choose the class map name from the drop-down list for which you want to add policer statistics. Each class map defines a a particular network traffic that is of interest to you.
Step 6. Click Apply.
Caution: This only saves your configuration to the running configuration file. This means any changes made will be lost if the device is rebooted. If you wish to save these changes even after a system reboot, you need to copy the running configuration file to the startup configuration file. See Copy Configuration File on SFE/SGE Series Managed Switches for more information on how to do this.
