How do we limit bandwidth per port on a Cisco router, and which models will do the job?

We have a requirement to supply a leased line to a building which has two separate departments - and they want to limit the maximum bandwidth one of the departments can use to, say, 8Mb/s. Assuming one ethernet port for each department, what's the least expensive model of Cisco router that will do the job properly, and what commands would we use to configure this?

Thanks

Just about any Cisco router will handle this.

You set the maximum rate per-port on a Cisco using the "rate-limit" command; you can rate-limit inbound, outbound, or both.

Sorry, that should be "per interface".

Router(config)# interface f0/0/0
Router(config-if)# rate-limit input 1000000 20000
Router(config-if)# rate-limit output 100000 30000

you can try the following command on the interface:

rate-limit input [bps] [normal burst bytes] [max burst bytes] conform-action transmit exceed-action drop

Would it need to be a router with QOS available in the IOS image?

Its called Traffic Shaping and if you want to do it, Visit http://www.cisco.com/en/US/docs/ios/12_1/qos/configuration/guide/qcdgts.html and check it out. As to which routers will do it, that will take a bit more research.

Most routers do it. but it sounds like your making a business decision. What I would do is call cisco directly, youll get an answer within 10 minutes. (408)526-4000

Good luck friend, Theyll give you all the information you need. cheapest wuold probably be a catyl 6500series

dont forget that switches can limit bandwidth as well, this would decrease price significantly. But If you prefer a router, that works too.

You can go to the feature navigator. Go to Search by Feature and search for "Rate-Limiting Inspected Traffic".

http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp


It will tell you which IOS's you can use.

asavener is correct.

Here is a link with some more information.

No.  I believe this feature is available in the 800-series routers.

The project has changed slightly now, so we won't get to actually try this for real - at least not yet - but I'm going to hand out the points now anyway.  Thanks for the advice.
