Manage Bandwidth to Internet

[jweldin]

I have an Internet router that has a T1 card. Is it possible to limit one set of IP addresses that access the Internet to a certain bandwidth, while giving another set of IPs full access to the bw?

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
