Information


While Q-SYS no longer validates switches (as testing is done at the University of New Hampshire InterOperability Laboratory), the Cisco SG350 switch can be set with the following suggested settings for Q-LAN or AES67 traffic.

  • Make certain IEEE Green Power/Cable Length detection is turned off for the switch.
  • Jumbo Frames should not be enabled.
  • In Quality of Service -> General -> QoS Properties, select the QoS mode option of Basic and select the Apply button.
  • Quality of Service -> General -> Queue -> select Strict Priority for all of the available Queues
  • Quality of Service -> General -> DSCP to Queue -> set all Queues to 1, then adjust to the following and press the Apply button:
    • If the design is set for Q-LAN
      • 46(EF)     = 7 (or the highest sometimes 5)
      • 34(AF41) = 6 (or the second highest)
      • 26(AF31) = 5 (or the third highest)
      • all others leave at Output Queue of 1
    • If the design is set for Audinate
      • 56(CS7)  = 7 (or the highest sometimes 5)
      • 46(EF)     =6 (or the second highest)
      • 26(AF31) = 5 (or the third highest)
