8.5.4 Weighted Fair Queuing – Expedite Mode

In the WFQ policy, between one and four queues (default is two) (Q8 to Q5 only) can be configured as

expedite (priority) queues. This is achieved by enabling the expedite function (set cos expedite queue

[on|off]) and selecting the required number of priority queues. The traffic directed to the priority queue(s)

will now be given priority up to their assigned CIR, but the priority queue(s) will not be able to access any

available surplus bandwidth in the system. This will be shared by the remaining non expedite queues

based on their weighting values.

Note that all queues that are NOT configured as expedite queues cannot have the sum of all assigned

CIR’s exceeding 100% of the system current speed. Queues configured as expedite queues can each be

assigned a CIR of up to 100% of the system current speed.

Note of caution: It is recommended that the sum of the CIR of all queues, including priority

queues, be set to <=100. If this rule is not followed, the WFQ behavior of the queues cannot be

guaranteed.
