Networked-Based Application Recognition (NBAR) for Classification

Networked-Based Application Recognition (NBAR) for Classification

Router(config)# interface fastethernet 0/0 Moves to interface configuration mode.
Router(config)# ip nbar protocol-discovery Turns on NBAR protocol discovery at the interface.
Router(config)# exit Returns to privileged mode.
Router# show ip nbar port-map protocol-name Displays the TCP/UDP port number(s) used by NBAR to classify a given protocol.

Displays the statistics for all the interfaces on which NBAR is enabled.


Note

NBAR is the discovery mechanism for class-map "match" statements when filtering by protocol.
