Configuring Inspection for Management
Application Protocols
This chapter describes how to configure application layer protocol inspection. Inspection engines are
required for services that embed IP addressing information in the user data packet or that open secondary
channels on dynamically assigned ports. These protocols require the ASA to do a deep packet inspection
instead of passing the packet through the fast path. As a result, inspection engines can affect overall
throughput.
Several common inspection engines are enabled on the ASA by default, but you might need to enable
others depending on your network.
