undo queue-scheduler
View
System view, Ethernet port view
Parameters
strict-priority: Uses the Strict Priority (SP) algorithm for queue scheduling.
wfq: Uses the Weighted Fair Queuing (WFQ) algorithm for queue scheduling.
queue0-width queue1-width queue2-width queue3-width queue4-width queue5-width queue6-width
queue7-width: Customizes the bandwidth values to be allocated for queues 0 through 7, in kbps. In
system view, the bandwidth ranges from 0 to 99968. The bandwidth varies with the port type as follows.
z Fast Ethernet port: 0 to 99968;
z Gigabit Ethernet port: 0 to 1000000.
Bandwidth granularity is 64 kbps. Assume that the value provided is in the range N*64 to (N+1)*64 (N is
a natural number), it will be round off to (N+1)*64 automatically. A value of 0 means the corresponding
queue adopts the SP algorithm for queue scheduling.
wrr: Uses the Weighted Round Robin (WRR) algorithm for queue scheduling.
queue0-weight queue1-weight queue2-weight queue3-weight queue4-weight queue5-weight
queue6-weight queue7-weight: Customizes the weights to be assigned to queues 0 through 7. The
value ranges from 0 to 15 in both system view and Ethernet port view. A value of 0 means the
corresponding queue adopts the SP algorithm for queue scheduling.
Description
Use the queue-scheduler command to configure the queue scheduling algorithm and the related
parameters.
Use the undo queue-scheduler command to restore the default.
By default, the WRR algorithm is used for all the output queues of a port. The default weights of queues
0 through 7 are 1, 2, 3, 4, 5, 9, 13, and 15, as shown in
Table 1-9.
