How can I limit bandwidth in Ethernet port of my router

[josephpjob]

Hi Group,

I have one Cisco 4500 with two ether net interfaces.

It is 10base-t port. My requirement is, I want to limit the bandwidth in eth0 as 512kps. How can I do that in Cisco...

Hi,

You have to apply Committed Access Rate for this.....If you have to apply this 512 Kbps to all the packets going through eth0 then appy this command to your etho ,

rate-limit output 512000 64000 64000 confirm-action transmit exceed-action drop

rate-limit input 512000 64000 64000 confirm-action transmit exceed-action drop

Or

If u want to restrict only some of the machines to use the specified bandwidth you can create an extended or standard access-list permitting the IP's of those machines which u want to restrcit and bind that access-list in the rate-limit command in your ethernet interface.As below,

router#access-list 10 permit 10.0.0.32 0.0.0.15

router#rate-limit access-group 10 output 512000 64000 64000 confirm-action transmit exceed-action drop

router#rate-limit access-group 10 input 512000 64000 64000 confirm-action transmit exceed-action drop

This will restrcit only the machines which comes under the access-list 10.

All the best.
