- How To Configure Qos On Cisco Router
By using QoS (Quality of Service) on your Cisco router, you can help in offering both the bandwidth and priority factors to particular types of network traffic. Usually, the network administrator will instruct the network devices about the usage of bandwidth and priority.Configuring QoS on your Cisco router might be a complicated procedure. Let us now discuss configuring basic QoS for a certain scenario by making use of a how to configure QOS on Cisco router steps:
Assume That You Have A Cisco 871W Router In Your House For The Following Activities:
- You are also making use of the router for usual internet operations like browsing, emailing, etc.
In case you encounter performance issues with any one or more of the above activities while using how to configure QOS on Cisco router steps, this is where QoS comes in handy.
Follow The Instructions Given Below To Configure Qos On A Cisco Router:
1. Defining the traffic:
- You can define the traffic by using either an ACL (Access Control List) or an NBAR (Network-Based Application Recognition). If you wish to use the traditional way of defining traffic for your Cisco router, you can go for ACL.
2. Creating a class-map:
- A class-map categorizes the traffic into various groups. For instance, you can form a class-map by the name of “VoIP traffic” and put all the VoIP protocols under the same.
3. Creating a policy-map:
- When you proceed with how to configure QOS on Cisco router steps, A policy-map does the function of matching the classes from your class-map to the bandwidths or priorities that you assign.
4. Applying your policy-map to the interface:
- Now, you need to apply your policy-map to a specific interface. You have the facility of applying your policy-map in the input or the output mode. To do the same, make use of the following command:
Service-policy output/input {name of policy-map}
In case you are using NBAR for recognizing traffic of router setup, you also have to use the command ip nbar protocol-discovery on the interface.
5. Downloading the QoS template:
Once you are familiar with the simple, basic steps for configuring QoS, you can go on to the process of downloading the QoS template.
- First, download the QoS template from the website.
- Open your Excel file and start filling up the yellow areas on the Variables worksheet.
- Now, click the Replace button. This action will create the QoS configuration on a fresh sheet known as QOS-1.
- Finally, from the Excel file, copy the configuration. Then, paste it in the Cisco CLI.
- We have now seen the how to configure QOS on Cisco router instructions of configuring QoS on your Cisco router.
