How to change the management interface on a 10200v?

As TayF5un indicated, you can use a self IP to gain administrative access your BIG-IP system, so long as you open it up for the appropriate ports - 22 and 443 being the default for command line and GUI access respectively. I would add that any self IP you do use should be non-public facing and ideally on a dedicated VLAN so that administrative traffic and application traffic do not compete for bandwidth. You can also further secure administrative access to the BIG-IP system using SSH and HTTPD allow lists. You can find a good reference guide here. (https://support.f5.com/csp/article/K13092)
