@Skynet_india hi, you can add multiple classifier and behavior in a traffic policy, for each combaination of the classifier and behavior, the traffic policy will check one by one, until match one of them or match nothing.
such as
traffic clas t1
if-match xx
traffic clas t2
if-match xx
traffc beha t1
traffic beha t2
traffic policy T
class t1 beha t1
class t2 beha t2

then apply traffic policy under the interface view, the traffic policy will check classifier t1 behavior t1 first, then classifier t2 behavior t2.

  • Traffic policing, traffic shaping, and interface-based rate limiting are valid for data packets and protocol packets sent by the local device, and are invalid for protocol packets sent to the CPU.
  • Traffic suppression in a VLAN, inbound interface-based rate limiting, MQC-based traffic policing, and ACL-based traffic-limit share CAR resources of the device. When CAR resources are insufficient, some of the preceding functions may fail to be configured. Run the display acl resource [ slot slot-id ] command to view the usage of CAR resources.
  • The inbound traffic statistics takes effect before interface-based rate limiting. That is, you cannot check whether interface-based rate limiting takes effect according to the traffic statistics. Run the display qos statistics interface interface-type interface-number inbound command on the S5720EI, S5720HI, S6720EI, and S6720S-EI to view traffic statistics after rate limiting is configured. In V200R010C00 and later versions, this command can be used on all switches to view traffic statistics after rate limiting is configured.
  • When traffic policing and another flow action are defined in different traffic behaviors of the same traffic policy and priorities of matching traffic classifiers are different, if packets match multiple traffic classifiers, only the action corresponding to the high-priority traffic classifier takes effect. In this case, rate limiting may fail.
