Configuring
Queue-scheduling
Refer to Queue Scheduling for the introduction to queue scheduling.
Configuration
Prerequisites
■ The queue-scheduling algorithm is specified: which queues adopt the SDWRR
queue-scheduling algorithm and which queues adopts the SP queue-scheduling
algorithm
■ If the SDWRR queue-scheduling algorithm is adopted, the queues and their
weights in WRR scheduling group1 and WRR scheduling group2 must be specified
Configuration Procedure
of the SP Queue
Scheduling
Start TS and send the
packets at a even rate
traffic-shape [ queue
queue-id ] max-rate burst-size
Required
The switch supports two forms of TS:
■ TS for all the traffic on the port.
The function can be implemented
when the queue queue-id
keyword is not specified in the
traffic command
■ The function of TS for the
specified output queues can be
implemented when the queue
queue-id keyword is specified in
the traffic-shape command.
