I have a cisco catalyst 4506 switch with a supervisor IV engine. We are looking to limit the bandwidth of a particular vlan that is coming into the switch. We share a 5 MBPS connection with 2 other entities. They come into our 4506 via fiber and then thru copper to our ISP's router. They are on their own vlan(Vlan 902). Since they are a school they are always using up all available bandwidth and the natives (my people) are getting upset at the fact that Dial up internet is faster.
My question is how do i limit the total amount of bandwidth on that vlan to only 1.5 mbps total for that vlan. I just want them to be limited to that amount and that amount only. We would then have the remaining 3.5 mbps to divide up amongst us and the other entity whom need it more.
