Entry a All
config scheduling_mechanism
Purpose Used to configure the scheduling mechanism for the QoS function
Syntax
config scheduling_mechanism [strict | weight_fair]
Description
The config scheduling_mechanism command allows the user to
select between a Weight Fair (WRR) 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 highest class of
service will transmit its packet before allowing the lower class to
