Software Configuration Guide for Cisco IWAN on APIC-EM

Categorize Applications

The Categorize Applications window shows application policies and categories to which the applications are assigned. You can use options to change the bandwidth used by applications in the network.

Applications are grouped into categories. To find the category to which an application belongs, enter the application name in the search textbox to the right of the window.

Click a category (for example, backup-and-storage), to see the applications assigned to the category in a drop-down box. The attributes of an application can be edited by clicking the pencil symbol next to the application name in the drop-down box.

You can keep track of application bandwidth usage at each category and move applications between application categories. Categories are grouped into Business Critical, Scavenger and Default groups. The Business Critical group is given the most bandwidth.

Add Application

Click “Add Application” to provide details of a new application and assign it to a category.

Enter values in the following fields:

To define the application policy groups, click “Define Application Policy.”

Define Application Policy

Applications are grouped into categories, such as “Voice and Video”. The categories form part of the following business groups: Business Critical, Scavenger and Default.

Change Application Performance

Click on the down arrow next to a category to change the Application Performance in the category to perform the following:

• Enable or disable application performance
• Enable or disable path preference
• Choose primary and secondary path
• Secondary path can be Drop

Select a Path Preference, with Path 1 being the preferred path for traffic in this category. For example, “Int” (Internet).

If you specified metered link as a link type for a service provider, the following dialog appears.

The metered link is the last resort when the primary, secondary, and tertiary paths are not available.

After updating the path preference, click Save.

Note The Save option does not check for validations in conflict with future scheduled workflows. Please reevaluate scheduled jobs based on these changes and update scheduled jobs as required. If there is a conflict when the scheduled job is activated, it may fail at that time.

Move an Application Category

You can drag-and-drop a category from one business group to another; for example, from Default to Scavenger.

Bandwidth Usage

You can view the bandwidth used across various applications in a location by selecting “Bandwidth Usage.” This provides a applications used per location, the bandwidth per Mbps, and the link SLA capacity for each router in a location in pie chart.
