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

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)

------------ ----- -------------- -------------- -------------- -------------- -------------- -------------- -------------- -------------- -------------- --------------

control-port 0     100000         100000         100000         100000         100000         100000         100000         100000         100000         100000

data-port    129   50000          100000         100000         100000         100000         100000         100000         100000         100000         100000

span-ports   130   100000         100000         100000         100000         100000         100000         100000         100000         100000         100000

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.
