OnTap 9 trusted hosts

Hi,

In 7Mode, System Manager could setup trusted hosts allow specific ip address for adminitration. But OnTap 9, I cannot found setup trusted hosts in System Manager, I also try modify firewall policy mgmt allow specific ip address access mgmt http, https and ssh, the cluster management LIF also apply mgmt firewall policy, but another IP still could access and login, any idea?

Best regards,

Chung
