WEB OPERATION & CONFIGURATION
Weight mode:
Deficit Weighted Round-Robin (DWRR) queuing which specifies a scheduling weight for each
queue. (Options: Strict, Weighted; Default: Strict) DWRR services the queues in a manner similar to WRR, but the
next queue is serviced only when the queue’s Deficit Counter becomes smaller than the packet size to be
transmitted.
Queue Shaper/Port Shaper/Queue Shaper
Enable:
Select the checkbox to enable queue shaper on a certain queue for this selected port.
Rate:
Indicate the rate for the queue shaper. By default, 500kbps is used. Allowed range for kbps is 100 to 1000000.
Allowed range for Mbps is 1 to 3300Mbps.
Unit:
Select he unit of measure for the queue shaper.
Excess:
Select the checkbox to allow excess bandwidth.
Queue Schedule
Queue Scheduler:
When Scheduler Mode is set to Weighted, the user needs to indicate a relative weight for each
queue. DWRR 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.
Weight:
Assign a weight to each queue. This weight sets the frequency at which each queue is polled for service and
subsequently affects the response time software applications assigned a specific priority value.
Percent:
The weight as a percentage for this queue.
Port Shaper:
Set the rate at which traffic can egress this queue.
Enable:
Select the checkbox to enable Port shaper.
Rate:
Indicate the rate for Port Shaper. By default, 500kbps is used. Allowed range for kbps is 100 to 1000000.
Allowed range for Mbps is 1 to 3300Mbps.
Unit:
Select the rate of measure
3.23.5 Port Shaping
This displays each port’s queue shaper and port shaper’s rate.
Click the port number to modify or reset queue shaper and port shaper’s rates. See “Port Scheduler” for detailed
explanation on each configuration option.
