JetStream 52-Port Gigabit Stackable L3 Managed Switch CLI Guide
Parameter
sp —— Strict-Priority Mode. In this mode, the queue with higher priority will
occupy the whole bandwidth. Packets in the queue with lower priority are sent
only when the queue with higher priority is empty.
wrr —— Weight Round Robin Mode. In this mode, packets in all the queues
are sent in order based on the weight value for each queue. The weight value
ratio of TC0, TC1, TC2, TC3, TC4, TC5 and TC6 is 1:2:3:4:5:6:7.
spwrr —— Strict-Priority + Weight Round Robin Mode. In this mode, the
switch provides two scheduling groups, SP group and WRR group. Queues in
SP group and WRR group are scheduled strictly based on Strict-Priority mode
while the queues inside WRR group follow the WRR mode. In SP + WRR mode,
TC6 is the SP group; TC0 to TC5 belong to the WRR group and the weight
value ratio of TC0 to TC5 is 1:2:3:4:5:6. In this way, when scheduling queues,
the switch allows TC6 to occupy the whole bandwidth following the SP mode
and TC0 to TC5 in the WRR group will take up the bandwidth according to
their ratio 1:2:3:4:5:6.
Command Mode
Global Configuration Mode
Example
Specify the Schedule Mode as Weight Round Robin Mode:
T3700G-52TQ(config)#classofservice queue mode wrr
24.6 classofservice queue min-bandwith
Description
The classofservice queue min-bandwith command is used to configure the
minimum guaranteed bandwidth allocated to the specified queue. A value of 0
means there is no guaranteed minimum bandwidth in effect (best-effort
service). The default value is 0. The sum of all bandwidth values for the
queues must not exceed 100%.
Syntax
classofservice queue min-bandwith
tc-id bw
Parameter
tc-id
—— The egress queue the packets with tag are mapped to. It ranges
from 0 to 6, which represents TC queue from TC0 to TC6 respectively.
