SWG - Ethernet Port Configuration and Network Status
Under Administration > Configuration > Network, the GUI should provide visual feedback on the cabling status depending on the operating mode configured (Port Span/Tap or Inline).
I.E, if the management cable is not connected when in inline mode, it should alert the admin of that fact:
Monitor (in black because is not used)
Management (in red because is disconnected)
LAN (in green because is connected)
WAN (in green because is connected)
It would be nice to have an Ethernet status summary entry on the Administration > System Status page so if any of these items is reporting a status in red, you can click on the status (that would be also a link) to check what the problem is.
