Poly TC8 - View Connections to the System; System Port Usage

• The PAC file must contain pure JavaScript.
• Poly recommends your PAC files use the .pac or .proxy extension.
• Poly supports PAC JavaScript functions that return “PROXY host:port” and “DIRECT”. Poly doesn’t support return
values of “SOCKS”, “HTTP host:port”, or “HTTPS host:port”.
View Connections to the System
Access a list of current connections to your system.
The list provides the following information:
• Type of connection (for example, web)
• ID associated with the session (for example, admin or user)
• Remote address (IP addresses of the hosts accessing your system)
This list doesn’t show details related to sharing content. For example, if someone shares a video from an HDMI-connected
laptop, you don’t see that this device is connected to the system.
