A BIG-IP Administrator is receiving intermittent reports from users that SSL connections to the BIG- IP device are failing. Upon checking the log files, the BIG-IP Administrator notices the following

2000 TPS is the sum of client-side and server-side TPS, but F5 typically licenses SSL TPS based on the higher of the two, not their aggregate.

400 TPS is insufficient as it is lower than both the client-side (1200) and server-side (800) peak TPS, and would not resolve the rate limit issue.

800 TPS is insufficient because the client-side SSL TPS reached 1200, which exceeds this capacity and would still trigger the rate limit error.

F5 BIG-IP SSL TPS licensing is calculated based on the higher value between client-side and server-side SSL transactions per second. Since the client-side SSL TPS reached 1200 and server-side reached 800, a license capacity of at least 1200 is required to prevent the 'SSL transaction (TPS) rate limit reached' error.
