Example usage:
To configure traffic scheduling:
DGS-3324SRi:4# config scheduling 0 max_packet 15
Command: config scheduling 0 max_packet 15
Success.
DGS-3324SRi:4#
Example usage:
To configure a Combination Queue with a Class 6 priority class with strict priority and the remaining classes as
weighted round robin (WRR) scheduling:
xStack Gigabit Layer 3 Switch Command Line Interface Manual
Entering a 0 into the <value 0-15> field of the max_packet
parameter allows for the creation of a Combination Queue for the
forwarding of packets. This Combination Queue allows for a
combination of strict and weight-fair (weighted round-robin "WRR")
scheduling. Priority classes that have a 0 in the max_packet field
will forward packets with strict priority scheduling. The remaining
classes, that do not have a 0 in their max_packet field, will follow a
weighted round-robin (WRR) method of forwarding packets — as
long as the priority classes with a 0 in their max_packet field are
empty. When a packet arrives in a priority class with a 0 in its
max_packet field, this class will automatically begin forwarding
packets until it is empty. Once a priority class with a 0 in its
max_packet field is empty, the remaining priority classes will reset
the weighted round-robin (WRR) cycle of forwarding packets,
starting with the highest available priority class. Priority classes
with an equal level of priority and equal entries in their
max_packet field will empty their fields based on hardware priority
scheduling.
<class_id 0-6> − Specifies which of the seven hardware priority
classes the config scheduling command will be applied to. The
seven priority classes are identified by number − from 0 to 6 − with
queue 6 being the highest priority.
max_packet <value 0-15> − Specifies the maximum number of
packets the above specified priority class will be allowed to
transmit per weighted round-robin (WRR) cycle. A value between
0 and 15 packets can be specified. A zero (0) denotes strict
priority scheduling for that priority class.
Only administrator-level users can issue this command.
