F5 Networks F5CAB5 Exam - Topic 3 Question 4 Discussion

Troubleshooting failed SSL handshakes involves interpreting the resource limits defined by the system's license8888. The log message SSL transaction (TPS) rate limit reached indicates the BIG-IP is dropping SSL connections because it has exceeded its licensed 'Transactions Per Second' capacity. When analyzing stats to determine the correct license level, the administrator must focus on 'Client-side' SSL TPS. This represents the initial encrypted handshakes between users and the BIG-IP virtual servers91. In this scenario, the peak client-side demand is 1200 TPS. While the 800 server-side transactions represent re-encryption toward the backend, F5's primary SSL TPS license limits typically apply to the client-facing side of the traffic flow. Therefore, to resolve the intermittent connectivity issues and ensure the virtual server works reliably during peaks, the license must be upgraded to at least 1200 TPS949596969696. 9798Confirming this peak via statistics and comparing it to the current license is a standard troubleshooting step for SSL performance issues.
