Get A Grade on SSL LAB for VIP
Try this one which I found in a thread on the old devcentral:
!SSLv2:!EXPORT:!DHE+AES-GCM:!DHE+AES:!DHE+3DES:ECDHE+AES-GCM:ECDHE+AES:RSA+AES-GCM:RSA+AES:ECDHE+3DES:RSA+3DES:!3DES:-MD5:-SSLv3:-RC4
I also have the following options enabled in the SSL client profile: no SSLV3, no TLSv1, and no TLSv1.1.
Here's how it comes out on SSL labs:
I find that I can get similar results locally using nmap's nse script to enum-ssl-ciphers like so:
PS C:\Users\user\nmap-7.70> .\nmap.exe -sV --script ssl-enum-ciphers -p 443 hostname.organization.com

Nmap done: 1 IP address (1 host up) scanned in 27.81 seconds
It's nice to not be dependent on an external resource for a quick, repeatable check and also not forget to hide the results.
Good luck!

Can u please suggest a cipher string for V 13.0 as grade has been changed but Weak Cipher s issue still persists .
Here is the string :
!SSLv2:!TLSv1:!TLSv1_1:!EXPORT:!DHE+AES-GCM:!DHE+AES:!DHE+3DES:ECDHE+AES-GCM:ECDHE+AES:RSA+AES-GCM:RSA+AES:ECDHE+3DES:RSA+3DES:!SSLv3

This works but I think you'll definitely see downlevel client failures:
!SSLv2:!TLSv1:!TLSv1_1:!EXPORT:!DHE+AES-GCM:!DHE+AES:!DHE+3DES:ECDHE+AES-GCM:!ECDHE+AES:!RSA+AES-GCM:!RSA+AES:!ECDHE+3DES:!RSA+3DES:!SSLv3
