Hello, friend!
You can run the car-port(distributing-mode) command to limit the rate of packets with a specified priority on an interface.
You can run the car-port cos-group-table command to bind a GEM port to a CoS group profile. After a CoS-group profile is bound to a GEM port, the rate can be limited based on the CoS-group.
You can run the car-port cos-group command to limit the rate of a specified CoS group on a GEM port. After this command is executed successfully, if the CoS of the packets passing through the GEM port belongs to a specified CoS-group, the system limits the rate of the packets based on the traffic profile referenced by the CoS-group.
Thanks!
