How to configure an AR to limit the rate of traffic based on MAC addresses
You can configure a traffic policy to limit the rate of traffic based on MAC addresses as follows: # traffic classifier mac1 operator and if-match source-mac 0015-c50d-0001 //Configure a matching rule based on the source MAC address 0015-c50d-0001 in the traffic classifier mac1. traffic classifier mac2 operator and if-match source-mac 0015-c50d-0002 //Configure a matching rule based on the source MAC address 0015-c50d-0002 in the traffic classifier mac2. traffic classifier mac3 operator and if-match source-mac 0015-c50d-0003 //Configure a matching rule based on the source MAC address 0015-c50d-0003 in the traffic classifier mac3. # traffic behavior d1 car cir 3000 cbs 564000 pbs 939000 mode color-blind green pass yellow pass red discard //Create the traffic behavior d1 and configure the rate limit to 3000 kbit/s. # traffic policy myqos //Configure the traffic policy myqos. classifier mac1 behavior d1 //Bind the traffic classifier mac1 to the traffic behavior d1. classifier mac2 behavior d1 //Bind the traffic classifier mac2 to the traffic behavior d1. classifier mac3 behavior d1 //Bind the traffic classifier mac3 to the traffic behavior d1. # interface GigabitEthernet 0/0/0 ip address 10.1.1.1 255.255.255.0 traffic-policy myqos inbound //Apply the traffic policy myqos to the inbound interface. #
