Describes how to deploy enhanced app-aware routing configurations from Cisco Catalyst SD-WAN Manager to Cisco IOS XE Catalyst SD-WAN devices.
The procedures in this section describe how to deploy the enhanced app-aware routing configurations from Cisco Catalyst SD-WAN Manager to Cisco IOS XE Catalyst SD-WAN devices.
Use one of these methods to configure enhanced application-aware routing:
Use these steps to configure enhanced application-aware routing (EAAR) using a configuration group in Cisco SD-WAN Manager.
| 1. | From the Cisco SD-WAN Manager menu, choose . |
|||||||||||||||||||||||||
| 2. | Choose a configuration group. |
|||||||||||||||||||||||||
| 3. | Under Actions, click Edit. |
|||||||||||||||||||||||||
| 4. | Under Feature Profiles, click System Profile. |
|||||||||||||||||||||||||
| 5. | Choose basic and under Actions, click Edit Feature. |
|||||||||||||||||||||||||
| 6. | In the Edit Basic Feature page, use the Enhanced App-Route field and choose one of the modes below:

| 7. | Click Save. |
Use these steps to configure enhanced application-aware routing using CLI commands to enforce SLAs and optimize routing decisions based on application performance metrics.
| 1. | Enable enhanced PfR measurements for SLA enforcement. Example:Enabling the application-aware routing feature on a Cisco IOS XE Catalyst SD-WAN device requires you to enable the PfR CLI on both the remote and local routers.
|
|
| 2. | Modify poll interval and multiplier settings for SLA enforcement and switchover. Example:The default poll-interval is 10 seconds and multiplier is 6 for SLA enforcement and switchover. The aggressive mode setting for app route pfr multiplier is 6 by default; it is 5 for moderate mode. Use the bfd enhanced-app-route ignore-local-loss command to ignore local loss on the router caused by QoS queues. By default, loss includes both local and WAN loss. |
|
| 3. | Configure SLA dampening time and multiplier. Example:SLA dampening time is the waiting period before returning the tunnel to SLA buckets after meeting the SLA. The default time is 120 seconds. The aggressive mode setting for dampening multiplier is 120 by default. |
