Limit-Bandwidth

Hi experts,

I hava 5Mb comes to my router and I have 12 vlans I want to reserve 2Mb for one vlan and divide the rest on other vlans. How can I do this by command without third party.

My router is cisco 2821 and 2960 TTL switch.

Thanks

Bandwidth command won't do you much good. it's only used for metrics, not actual limiting.

You're going to have to do some QoS with shaping commands. Here's a sample from one of my switches. You will have to do it on your router, and the router has more capabilities than my switch, but here's a start for you.

It'll probably be better for you to do a nested QoS. Limit the whole interface for 5Mb, then do another QoS layer with your important VLAN as priority, then leave the class default as is.

Anyways, check out my config below so you can see how I'm shaping my traffic, but then create one yourself by following the guide below.
