Comprehensive and Detailed Explanation From BIG-IP Administration Supp13ort and Troubleshooting documents: When troubleshooting a Virtual Server that is not working as expected, it is critical to ensure that the applied profiles match the type of traffic being processed. SSH (Secure Shell) is a non-HTTP protocol that operates over TCP. The exhibit indicates that an HTTP profile is applied to the Virtual Server14. An HTTP profile instructs the BIG-IP system to parse traffic as HTTP; however, since SSH traffic does not follow HTTP specifications, the BIG-IP's parser will fail to understand the data stream, typically resulting in dropped packets or reset connections15. To fix this, the administrator must set the HTTP profile to "None"16. This allows the Virtual Server to act as a "Standard" or "FastL4" listener that passes the encrypted SSH data transparently to the backend pool members without attempting application-layer inspection. This highlights a common troubleshooting step: verifying that L7 profiles are not inadvertently applied to L4 traffic, which disrupts the expected traffic flow between the client and the server.
