Figure 7-6: QoS Egress Port Scheduler
Parameter descriptions:
Port: The logical port for the settings contained in the same row.
Scheduler Mode: Controls whether the scheduler mode is "Strict Priority", "WRR" or
"WFQ" on this switch port.
WFQ allows specifying, for each flow, which fraction of the capacity will be given.
WRR serves a number of packets for each nonempty queue.
In a Strict Priority queue, an element with high priority is served before an element with low
priority.
If two elements have the same priority, they are served according to their order in the queue.
Weight: Controls the weight for this queue. The default value is "0". This value is restricted to 1-100.
This parameter is only shown if "Scheduler Mode" is set to "Weighted" (
WRR or WFQ).
