Configuring Port Rate Limit
By using the command port-cos-rate-setting-modify, you can stipulate a port speed in packets per second (pps) to regulate the traffic corresponding to each QoS queue. This command is used for rate limiting the traffic of the port queues.
CLI (network-admin@switch) > port-cos-rate-setting-modify
port-cos-rate-setting-modify |
Modify port queue rate limit. |
port control-port|data-port|span-ports |
Specify the port type to set QoS rate limit. |
cos0-rate unlimited|0..10000000 |
Specify the rate limit (pps) for the queue. |
cos1-rate unlimited|0..10000000 |
|
cos2-rate unlimited|0..10000000 |
|
cos3-rate unlimited|0..10000000 |
|
cos4-rate unlimited|0..10000000 |
|
cos5-rate unlimited|0..10000000 |
|
cos6-rate unlimited|0..10000000 |
|
cos7-rate unlimited|0..10000000 |
|
cos8-rate unlimited|0..10000000 |
|
cos9-rate unlimited|0..10000000 |
For example:
CLI (network-admin@switch) > port-cos-rate-setting-modify port data-port cos0-rate 50000
To display the port rate limit configuration, use the command:
CLI (network-admin@switch) > port-cos-rate-setting-show
port ports cos0-rate(pps) cos1-rate(pps) cos2-rate(pps) cos3-rate(pps) cos4-rate(pps) cos5-rate(pps) cos6-rate(pps) cos7-rate(pps) cos8-rate(pps) cos9-rate(pps)

The output displays the port rate limit configuration for control ports, data ports, and span ports. The data ports and span ports are platform specific. The default rate for each queue is 100000 packets per second. The queues 8 and 9 must be enabled for the columns cos8-rate(pps) and cos9-rate(pps) to be displayed.
Note:
- The port-cos-rate-setting-modify and port-cos-rate-setting-show commands are available only when CPTP is disabled
- Queues 8 and 9 are available only on NRU01, NRU02, NRU03, and NRU-S0301 platforms.
