Configuring the Switch

Port to CoS

Modify the default priority for any interface using the text field provided..

Port  Displays the port number..

Default CoS (0-7) The priority that is assigned to untagged frames received on the interface.. (Range: 0-7, where 7 is the highest priority)

LAG  Indicates if ports are members of a LAG.. To configure the default priority for LAGs, go to the table entry for the LAG number, which is listed after ports Gig 1 and Gig 2 at the end of the table..

Default settings can be restored using the Restore Defaults button..

Click Save Settings to save the changes..

The 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 used to provide independent priorities for delay-sensitive data and best-effort data..

Queue Settings

You can set the Switch to service the queues based on a strict rule that requires all traffic in a higher priority queue to be processed before lower priority queues are serviced, or use Weighted Round-Robin (WRR) queuing that specifies a relative weight of each queue.. WRR uses a predefined relative weight for each queue that determines the percentage of service time the Switch services each queue before moving on to the next queue.. This prevents the head-of-line blocking that can occur with strict priority queuing..

•StrictPriority  Servicestheegressqueuesinsequential order, transmitting all traffic in the higher priority queues before servicing lower priority queues..

•WRR  Weighted Round-Robin shares bandwidth at the egress ports by using scheduling weights 1, 2, 4, 8 for queues 0 through 3 respectively..

Set the Queue Mode to Strict or WRR using the Queue Mode drop-down menu then click Save Settings

Queue Scheduling

The Switch uses the Weighted Round Robin (WRR) algorithm to determine the frequency at which it services each priority queue.. A weight is assigned to each of these queues (and thereby to the corresponding traffic priorities).. This weight sets the frequency at which each queue will be polled for service, and subsequently affects the response time for software applications assigned a specific priority value..

The queue weighting is fixed for the Switch and cannot be configured..
