Can Anyone please tell me which TLS version are used for ontap 8.2.x family & also how to check tls version?
See The Solution
Version 8.2 supports TLS v1.0.
Version 9.0 added TLS v1.1 and v1.2 support.
View solution in original post
Ontap version 8.2.5 also supports TLS versions 1.1 and 1.2.
The security scanning tool nmap has a scripting library as part of it.
There is a "ssl-enum-ciphers" script that ships in the standard nmap builds that tests a device for which TLS/SSL versions it supports, and which cipher suites it supports.
nmap --script ssl-enum-ciphers -p 443 126.96.36.199
Would help you understand both the versions and ciphers a web server supports
