Chapter 1 What’s New for FortiOS 5.2.1 : Usability Enhancements : Interfaces List Improvements
  
Interfaces List Improvements
Several improvements have been made to the Interfaces List:
Only interfaces with tunnels or VPNs expand to show more information.
The Status column shows the number of clients using the interface. Clicking on the number in the status column will direct you to the DHCP Monitor or wireless Client Monitor, depending on which type of clients are using the interface.
The protocols listed in the Access column have been assigned color codes. Secure services (HTTPS, SSH) are listed in grey, insecure services (TELNET, HTTP without HTTPS redirect enabled) are listed in red, and all other services are listed in blue.
