On AR routers in versions later than V200R002C00, you can run the qos car command to configure rate limiting based on network segments.

Configure rate limiting for a network segment on an AR
1. Configure an ACL to match the network segment on which the rate of packets needs to be limited. # acl number 2000 //Create ACL 2000. rule 0 permit source 192.168.1.0 0.0.0.255 //Configure rule 0 to allow packets with source IP address 192.168.1.0 to pass. # 2. Configure rate limiting for the data flow that matches a traffic classifier on the interface connecting to intranet users. # interface GigabitEthernet3/0/0 ip address 192.168.1.1 255.255.255.0 qos car inbound acl 2000 cir 512 cbs 32000 pbs 432000 green pass yellow pass red discard //Configure traffic monitoring for packets that match ACL 2000 on the inbound interface, and specify CIR to 512 kbit/s. #

Do S series switches support time-based rate limiting on interfaces
S series switches (except S1700 switches) do not support time-based rate limiting on their interfaces. You can configure traffic policing using ACLs and traffic policies for rate limiting in a specified time range.
