I need to give higher priority to multicast streams in GS-1900, how do I set this up?
You can use QoS setting on GS1900 with following steps.
1. Access the Switch via WebGUI.
2. Go to Configuration -> QoS -> General and choose the specific port (The port connected with stream server) to configure CoS Value to the priority you want. (Don't recommend to configure the highest priority 7 because priority 7 packet is usually reserved for the system packet.)
3. Go to Configuration -> QoS -> Trust Mode -> Port to configure port mode "Trust" on the port connected to stream server.
Then your stream should be set priority.
