You can use rate-limit committed access rate (CAR) which access-group sentence , Applies this CAR traffic policy to the specified access list.

Example:

int FastEthernet0/0

ip address 192.168.0.1 255.255.255.0

ip address 192.168.1.1 255.255.255.0 secondary

rate-limit input access-group 100 10000000 80000 80000 conform-action continue exceed-action drop

rate-limit input access-group 110 448000 8000 32000 conform-action transmit exceed-action drop

!

access-list 100 permit 192.168.0.0 0.0.0.255

access-list 110 permit 192.168.0.0 0.0.0.255
