QoS (Quality of Service)
3425-00669 Rev E 105
Queue Index —There are eight queues for each interface. You can configure the
parameters but cannot add or delete queues. Higher index queues generally
represent higher-priority queues. Queues 1-3 are Strict Priority (WP) queues, and
Queues 4-8 are priority-based Weighted Fair Queues (WFQ).
Precedence —Enter the Precedence value of this queue relative to the others. A lower
value indicates higher precedence.
Scheduler —Select the scheduling algorithm: SP , WFQ , or WRR (Weighted Round
Robin). The default is SP .
Dropper — Select the dropping algorithm used if there is congestion: RED (Random
Early Detection), DT (Drop Tail), or WRED (Weighted RED). The default is WRED .
Weight —When WFQ or WRR is used, this option is available and used only for
queues of equal precedence. Queues 4-6 have equal precedence, and Queues 7-8
have equal precedence. Queues 1-3 have higher precedence than Queues 4-6, while
Queues 4-6 have higher precedence than Queues 7-8.
Shaping —If the Shaping rate is greater than or equal to 100, then it is the percentage
of physical bandwidth. If the Shaping rate is less than 100, then it is the rate in bits
per second. A value of -1 indicates no shaping. The default is
-1 .
Burst Size —Enter the Burst Size in bytes (1 to 10485760). For both leaky bucket
(constant rate shaping) and token bucket (variable rate shaping) algorithms, the
Burst Size value is the bucket size and the maximum burst size. If you set this value
to zero, then the Gateway will use the system default Burst Size, which is the current
Shaping rate divided by eight. The default is
0 .
