SSL session reuse

[zoe]

I have 3 DX appliances, and one of them is not reusing SSL sessions: ReusedSessions is always 0 when checking SSL stats (show server stats history ssl listen). I had compared the configurations and I had found two paramaters for server factory settings that are differents, but I don't know what they mean. Those settings are:

Factory s scl

Factory s sct

They are disabled in the appliance that is not reusing SLL sessions, while enabled in the others.

¿Which is the meaning of those settings? ¿Are there other parameters influencing SSL session reuse?

Hello Zoe, 

I believe you have found the source of your issue.

The meaning of those commands is as follows:

Factory s scl = SSL Session Caching on the Listen side

Factory s sct = SSL Session Caching on the Target side

Thanks Christopher! I have just enabled the settings and CPU utilization has decreased in a 50%.
