NXA-ENET8-2POE - Instruction Manual
Port identifier.
Shows the scheduling mode for this port.
Shows the weight of each egress queue used by the port.
The switch can be set to service the queues based on a strict rule that requires all traffic in a higher priority queue
to be processed before the lower priority queues are serviced, or 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. Note that weighted scheduling uses a combination of weighted
service for queues 0 - 6, and strict service for the high priority queues 7 and 8.
Controls whether queue shaping is enabled for this queue on this port.
Enable - Enables or disables queue shaping. (Default: Disabled)
Rate - Controls the rate for the queue shaper. The default value is 500. This value is restricted to 100-1000000
Kbps, or 1-3300 Mbps.
Unit - Controls the unit of measure for the queue shaper rate as Kbps or Mbps. (Default: Kbps)
Excess - Controls whether the queue is allowed to use excess bandwidth. (Default: Disabled)
When the Scheduler Mode is set to Weighted, you need to specify 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 - A weight assigned to each of the queues (and thereby to the corresponding traffic priorities). This
weight sets the frequency at which each queue is polled for service, and subsequently affects the response time
for software applications assigned a specific priority value. (Range: 1-100; Default: 17)
Percent - The weight as a percentage for this queue.
Sets the rate at which traffic can egress this queue.
Enable - Enables or disables port shaping. (Default: Disabled)
Rate - Controls the rate for the port shaper. The default value is 500. This value is restricted to 100-1000000
Kbps, or 1-3300 Mbps
Unit - Controls the unit of measure for the port shaper rate as Kbps or Mbps. (Default: Kbps)
