Hello experts.
I need a way to manage bandwidth allocation at switch level for a customer. He wants to make sure that some computers in his network have a guaranteed bandwidth, but in the same time they don't exceed that limit.
For instance, he has 10 mbps from his ISP, and wants to be sure that few computers dedicated to management have 5 mbps guaranteed, but in the same time they don't exceed the 5 mbps limit. So, I thought that the easiest way is to place a switch just before the ISP router and to split the bandwidth at port level, with some ports for management having 5 mbps.
Now, I know that some Cisco Catalyst switches can do that, but I didn't do it until now. Of course Cisco Switches are expensive, so my questions are:
1. Only Cisco Switches do that?
2. If yes, what is the cheapest Cisco Switch that can do that.
3. If not, what other switches can do that?
4. I would like some hints for someone who already did that before, and possibly post some configuration examples.
They way it should be done is with QOS. QOS is configurable on almost all routers. If you are looking for the cheap route. Get a Linksys router that supports dd-wrt. Then you can configure port (thats tcp port) priority. So for instance you would configure port 21 with a lower priority than lats say port 80. Due to the large amount of traffic that ftp uses when doing a file transfer.
I believe dd-wrt does have the capability to specify interface (physical connection) priority but thats not the recommended solution.
