One user downloading something use all my WAN bandwidth

[elisha_miller1]

Whenever a user downloads something all other users have a slow connection to the internet. Is there a way to limit how much this impacts other users? I have a 4507R that is connected to the WAN and a 6509E for my routing.

for example you can limit total bandwidth for this user in access swich port to 50 mbit if you have internet 100mbit

You can police ingress traffic, but as that's often downstream of WAN link that's being congested, effectiveness varies.  You can also ask your ISP to configure QoS on their side, egress, but they will almost always say no (but they will often offer you the chance to purchase more bandwidth).

You can look into 3rd party traffic management appliances, which can do more for traffic management than even Cisco routers, but even those are not always 100% effective.
