How to do qos in cisco 3925 router ios ?

isp has 200 mbps i need to limit it to 30 mbps(1:1)  on each ports of the sg300 switch.

Hello,

actually the SG300 lets you configure single and aggregate policers that you can apply to all ports. Since you want the same 30MB limit on all ports, an aggregate policer would be sufficient.

Check page 506 of the attached user guide for a description on how to configure this:
