rate limit bandwidth

how can i limit the bandwidth usage of my WAN link ?

I have a 10Mb link from site office to HO.

recently, i notied that users at site office are accessing files from the HO network.

when they start the downloading, it takes up the whole 10Mb line.

how can i control the downloading of files to eg. 3Mb so that they would not choke up the 10Mb link ?

rate limit bandwidth

is there tools that I can use to see what traffic is going in/out of my network ?

currently, I do not have such tools.

Hi,

shaping and policing can limit the bandwidth to a configured rate. You can do that on HR to limit the traffic for site office. Netflow is the free tool to tell you what traffic is in/out of your network.

"How" is usually done by shaping or policing.

I have a 10Mb link from site office to HO.

recently, i notied that users at site office are accessing files from the HO network.

how can i control the downloading of files to eg. 3Mb so that they would not choke up the 10Mb link ?

"How" would depend on devices at each end of the link.  If you can identify the "bad" traffic, you can restrict their bandwidth transfer rate to your 3 Mbps, although if your equipment supports it, prioritizing "good" over "bad" traffic usually makes for a better performing network.  If you're wondering why, well if at some moment there's only "bad" traffic, why artificially restrict it to 30%?  Or, if at some other moment, "good" traffic desires 90%, it won't obtain it if you allow "bad" to always have 30%.

If your end devices are routers, and if they support FQ, that alone can often work wonders vs. using FIFO.

Re: rate limit bandwidth

most of the site office routers are 1841 and 1941.

for a start, i think i will enable netflow on the interface to see what are the traffic going in/out before doing any control.

will enabing the netflow commands choke up the routers ?

It usually doesn't offer too much additional load.
