Enable NBAR2 with ip nbar protocol-discovery on interface

First, enable NBAR2 on the interface using ip nbar protocol-discovery. Then create a class-map to match the application using match protocol. Next, create a policy-map to mark or apply QoS actions. Apply the policy-map to the interface. Finally, verify NBAR2 statistics using show ip nbar protocol-discovery.

Variation 1. Drag and drop the steps of NBAR2 application recognition and classification steps into the correct order, from first to last.

medium
  • ✓ A.Enable ip nbar protocol-discovery on interface
  • ✓ B.Create class map matching application
  • ✓ C.Create policy map with set dscp or set ip precedence
  • ✓ D.Apply service policy to interface
  • ✓ E.Verify with show ip nbar protocol-discovery

Why A: NBAR2 configuration begins by enabling the protocol discovery, then creating a class map to match the application, a policy map to mark traffic, applying it to the interface, and verifying the classification. NBAR2 uses deep packet inspection to identify applications.
