question related to SSL certificate

You certificate directly does not support SSLv3 as this is the SSL protocol version, on the LTM cli run the following: tmm --clientciphers DEFAULT

This will show a list of ciphers the F5 will allow by default. Check the client SSL profile 'Ciphers' is set to 'DEFAULT'.

By default F5 LTM does not allow SSLv3, if you need to enable is under the client SSL profile change the 'Ciphers' (need to show 'Advanced' view on the Web GUI) to the following 'DEFAULT:SSLv3'

List of supported cipher suites depends on F5 software version https://support.f5.com/kb/en-us/solutions/public/13000/100/sol13163.html
