Want to summarize with AI?

Provides information on verifying custom applications and protocols.

After you define a custom application, it appears in the Custom Application List, which shows all available protocols and custom applications. The Custom Application List is available here: Configuration > Policies > Centralized Policy > Add Policy > Custom Applications.

Verify protocols and custom applications on a device

Use the show ip nbar protocol-id command to display all protocols and custom applications that are loaded on the router. It is helpful to filter the results. For example, to display all protocols and custom applications with "custom" in the name, use this:

vm5#show ip nbar protocol-id | include custom
custom_amazon                    3899          PPDK LOCAL
custom_facebook                  3284          PPDK LOCAL

See show ip nbar protocol-id.
