how to disable SSLV3

The following post has all the info and links you need to address POODLE on your BIGIP: https://devcentral.f5.com/articles/cve-2014-3566-removing-sslv3-from-big-ip

Please read this SOL for F5's procedure on modifying your cipher lists: https://support.f5.com/kb/en-us/solutions/public/13000/100/sol13171.htmlblockspecific

If you are using the configuration utility (GUI), append the following to the cipher list of the custom client-ssl or server-ssl profile (never alter F5 default profiles): !SSLv3. An example would be "DEFAULT:!SSLv3". The CLI command would be something like the following, but you will want to use the profile's current cipher list and append :!SSLv3, otherwise you will replace it entirely with what is specified in the command:

tmsh modify ltm profile client-ssl (profile-name) ciphers DEFAULT:!SSLv3
