Expert Configuration

Configuration The Configuration page allows you to configure IPQoS for a given destination interface for the IPQoS queues instantiation.

When enabling or disabling IPQoS, take the following into account:

if the WAN interface (for example PPPoA, IPoA,...) is detached at the time of enabling/disabling IPQoS, then the WAN interface has to be attached in order for the enabling/disabling of IPQoS to take effect.

if the WAN interface is attached at the time of enabling/disabling IPQoS, then the WAN interface has to be detached and then re- attached in order for the enabling/disabling of IPQoS to take effect.

Following settings are available:

Name:

The destination interface for the IPQoS queues instantiation.

State:

Disable or enable IPQoS for the interface.

Discard:

Determines the packet discard strategy in case of congestion. Choose between:

tail: Tail Drop: arriving packets will be dropped as soon as the destination queue is in an overflow state.

early: Early Packet discard: arriving packets will be dropped early according to the BLUE active queue management algorithm.

Priority:

Select the subqueue priority algorithm. Choose between:

wfq:

Weighted Fair Queuing (WFQ) is used for the four AF queues. The realtime queue has priority over the WFQ queues, which have priority over the best-effort queue.

strict:

Priority queuing is used. Strict Priority scheduling is used between all queues. The higher the queue number, the higher the priority.

wrr:

Weighted Round Robin (WRR) is used for the four AF queues. Each queue is scheduled in turn, with a circular “round” wrapping.

WFQ queue Weight:

A number between 1 and 97. Represents the weight of the queue used for

WFQ or WRR.

Max highest queue rate (%):

Represents a percentage of the interface bandwidth for rate-limiting of the Real Time queue. In case of congestion, the Real Time queue will only use this percentage of the interface bandwidth when there is also traffic on the other queues. This prevents other queues from starvation (when the highest uses all bandwidth).

Max highest queue burst:

Represents the Real Time queue burst size (in kilobytes) for rate limiting.
