WRR-QUEUE EGRESS-RATE-LIMIT QUEUES
Syntax
wrr-queue egress-rate-limit bandwidth queues queue_numbers
Parameters
bandwidth
Specifies the maximum data. The options are:
– 1k to 41943040k: The k indicates Kbps. You can omit the k.
The maximum bandwidth for 10 Gigabit Ethernet ports is
10485760.
– 1m to 40960m: The m indicates Mbps. The maximum
bandwidth for 10 Gigabit Ethernet ports is 10240m. You
must specify the m.
– 1g to 40g: The g indicates Gbps. The maximum bandwidth for
10 Gigabit Ethernet ports is 10g. You must specify the g.
The units k, m, and g are not case-sensitive.
queue_numbers
Specifies one or multiple numbers of egress queues. The queue
number can be 0 to 7. Use a space to separate numbers.
Mode
Port Interface mode
Description
Use this command to set a limit on the bandwidth of egress queues on the
specified ports for the switch to perform traffic shaping. Traffic shaping is a
traffic management technique used to avoid congestion by meeting
downstream requirements and regulating the flow of traffic.
When the maximum bandwidth that you specify is not an increment of 8
Kbps, the system changes to a number that is larger than the specified
bandwidth and the closest increment of 8 Kbps.
You must enable QoS on the switch to use this command. To enable QoS,
see “MLS QOS ENABLE” on page 503.
To remove the maximum bandwidth specified on queues on the specified
ports, use the NO WRR_QUEUE EGRESS-RATE-LIMIT QUEUES
command.
