Protocol Inspectors

SUMMARY Protocol inspectors can identify protocols such as HTTP, POP3, FTP, and telnet. You can also exclude protocol inspectors. When the inspectors are excluded, any network traffic data that is associated with the inspector is still ingested, but the traffic is identified and indexed only on a generic level.

Any protocol that is not identifiable by a protocol inspector is categorized as Unknown.
