Maximum number of the qos car and traffic policy configurations on the same interface

1

You can run the qos car command in the interface or sub-interface view. If the ACL number, destination IP address range, or source IP address range is configured in the qos car command on WAN interfaces, you can run the qos car command repeatedly on an interface for a maximum of 16 times.
You can run the traffic policy command to create a traffic policy. A traffic policy can be applied to only one direction on an interface, and the device supports a maximum of 1024 traffic policies.

What is the limitation on qos car and traffic policy
The qos car command can be configured on an interface or a sub-interface. If the qos car command that is configured on a WAN interface defines the ACL number, or source or destination IP address range, the qos car command can be configured on the interface for 16 times. The traffic policy command creates a traffic policy. A traffic policy can be applied to one direction on an interface only. The AR supports a maximum of 1024 traffic policies.

If a traffic policy is applied to different interfaces, are CAR and GTS shared by these interfaces
If a stream policy is applied on different interfaces, the committed access rate (CAR) bandwidth and generic traffic shaping (GTS) bandwidth are independent for each interface. For example, if the behavior in a traffic policy sets the speed limit to 10 Mbit/s, and the traffic policy is applied to different interfaces, each interface can individually occupy a maximum bandwidth of 10 Mbit/s.

A traffic policy contains multiple pairs of traffic classifiers and behaviors. How to handle the problem if the GTS CIR command is executed in these pairs and the CIR configured is greater than the CIR configured on the interfaces
If a traffic policy includes multiple pairs of traffic classifiers and behaviors and the GTS CIR command is configured in these pairs. If the CIR of these pairs is greater than that configured on the interface, rate limiting will be configured for the pairs and interfaces.

Unit of rate limits for S series switches
The unit of rate limits for S series switches (except S1700 switches) is kbit/s.
