OptiSwitch® MR2226N-2C L2/4 Managed Switch
... The MR2226N-2C switch prioritizes each packet based on the required level of service, using four priority queues with strict or Weighted Round Robin Queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from the end-station application. These functions can be use ...
