28 Configuring Application
Fingerprinting
The OmniSwitch Application Fingerprinting (AFP) feature attempts to detect and identify remote applica-
tions by scanning IP packets and comparing the packets to pre-defined bit patterns (application signa-
tures). Once an application is identified, AFP collects and stores information about the application flow in
a database on the local switch. Additional configurable options for this feature include the ability to apply
QoS policy list rules to the identified flow and generating SNMP traps when a signature match occurs.
Using this implementation of AFP, an administrator can obtain more detailed information about protocols
running on a specific device or make sure that certain QoS actions are automatically applied wherever an
application might be running.

This chapter provides an overview of the Application Fingerprinting feature and describes how to config-
ure the port-based functionality and profile attributes through the Command Line Interface (CLI). CLI
commands are used in the configuration examples; for more details about the syntax of commands, see the
OmniSwitch CLI Reference Guide.
