Example usage:
To configure the traffic scheduling mechanism for each QoS queue:
Description This command is used to select between a weight fair and a strict
mechanism for emptying the priority classes of service of the QoS function.
The switch contains four hardware priority classes of service. Incoming
packets must be mapped to one of these four hardware priority classes of
service. This command is used to specify the rotation by which these four
hardware priority classes of service are emptied.
The switch’s default is to empty the four priority classes of service in order -
from the highest priority class of service (queue 3) to the lowest priority class
of service (queue 0). Each queue will transmit all of the packets in its buffer
before allowing the next lower priority class of service to transmit its packets.
Lower classes of service will be pre-empted from emptying its queue if a
packet is received on a higher class of service. The packet that was received
on the higher class of service will transmit its packet before allowing the lower
class to resume clearing its queue.
Parameters strict – Entering the strict parameter indicates that the highest class of service
is the first to be processed. That is, the highest class of service should finish
emptying before lower ones begin.
weight_fair – Entering the weight fair parameter indicates that the priority
classes of service will empty packets in a fair weighted order. That is to say
that they will be emptied in an even distribution.
Restrictions Only Administrator-level users can issue this command.
