NFM-P and NSP comparison: QoS

Before you begin

This use case shows how to use Infrastructure Configuration Management in NSP to discover an existing QoS policy from a device and synchronize it to other NEs in the network..

NFM-P method

For comparison, here are the steps we would have performed in the NFM-P to distribute the policy to multiple NEs.

Create the policy on the NE using CLI.
Choose Policies→QoS→SROS QoS→Access Egress→SAP Access Egress from the NFM-P main menu.
Click Search and select the new policy.
Double-click on the policy to open the Edit form.

The new policy is a local policy, in Draft configuration mode.
Click More Actions, Synchronize.
Choose the NE to which the policy is to be synchronized from the Available Local Policies list and click on the right-arrow. The chosen NE moves to the Selected Source Local Policy panel of the form.
Click Synchronize. The new local policy definition is synchronized with the global policy.
From the Edit form, click Switch Mode to release the policy and distribute it to other NEs.
Select the NEs for distribution in the Available Object panel and click on the right-arrow button.
Click Distribute.

The policy is now available on the selected NEs.

Infrastructure Configuration Management method

You can discover, release and distribute the new policy to classic or model driven NEs by deploying a configuration template.

In this example, the QoS policy has been created on the node using CLI.

The configuration template SAP Egress Policy has been created using the predefined icm-qos-sapegress-srqos intent type; see How do I import a configuration intent type? and How do I create a configuration template?.

To use this template to discover and distribute the new policy:

For this scenario, we will associate the template to the network. Associating the template ensures that no existing QoS policy values on the NE will be overwritten with template values.

Steps


1	Select SAP Egress Policy from the list of configuration templates and click (Table row actions), Associate to Network.
2	In the form that opens, click TARGET and choose NEs.
3	Choose the NE where the new policy is added and click ADD.
4	Select the existing policy name and ID for the NE and click ASSOCIATE.
5	The template has now been deployed. Double-click on the template to see the deployment in the list of deployments for the template.
6	Choose the deployment and click (Table row actions), Distribute.
7	In the Deploy Logical Configuration form that opens, click TARGET and choose NEs. All compatible managed NEs appear in the list, regardless of management type.
8	Select the NEs you want to distribute the policy to and click ADD.
9	Click DEPLOY. End of steps
