Change the default SSL version in F5

Hi Guys,   I am getting an error where F5 is initiating SSL handshake but not getting any response from server. When I checked with server team, they told F5 is sending SSLv3 and SSLv3 is disabled...

You cannot change the SSL behavior of a performance layer 4 VIP, because performance layer 4 VIPs don't have SSL settings.

 

If you do indeed have a performance L4 VIP configured, then IT IS NOT doing anything with the encryption between the client and server. You should probably do an ssldump on both sides of the VIP (client side and server side) to verify the SSL handshake traffic.
