Connectivity issue with Ontap 8.1 RC1 with TLS mode


I have disabled ssl and configured TLS on Ontap 8.1 RC1. Now I am not able to connect through Ontap 1.1 API. 


bas-netappv81> options ssl
ssl.enable on
ssl.v2.enable off
ssl.v3.enable off

bas-netappv81> options tls
tls.enable on


I got the below exception: Server chose TLSv1, but that protocol version is not enabled or not supported by the client.

Since the JRE 1.8 supports TLS by default, I have used the same JRE 1.8. Could anyone please point out whether I need to set any property in client side to enable TLS protocol?




There was a bug in Ontap 7 and a workaround: Enable SSLv3 and keep SSLv2 disabled


ssl.enable                  on        

ssl.v2.enable             off       

ssl.v3.enable             on        

myfiler> options tls

tls.enable                   on     





I have gone through the various release documents. Looks like NetApp has provided TLS support in 5.0. So I have used manageontap-5.2.2.jar from SDK 5.2.2. Now I am able to connect NetApp Ontap 8.1 with TLS enabled.
