Hi there,
Yes, u can use rate-limit (CAR) and matching on a certain ACL which matches that certain ip address(s) and police the bw untilization used by this IP to a certain limit:
Match the desired ips in an access-list:
access-list 10 permit host x.x.x.x
Under the internet interface apply this rate-limit command (this example polices at 1M):
rate-limit input access-group 10 1024000 192000 384000 conform-action transmit exceed-action drop
rate-limit output access-group 10 1024000 192000 384000 conform-action transmit exceed-action drop
