I have question about traffic policing and I am not sure where should I implement it. I have server (10.1.1.1.2) in the access gig switch (Cat-3750) want to limited to like 500MB only when it cross different vlan (192.168.1.2). We have 6513 is acting as Distribution/Core, and distribution is a layer 2 switching (Cat-3750). I want to apply the traffic policing (drop the traffic) on edge switch if possible. So I am wondering if I can use ext. acl in access switch with source 10.1.1.2 dest 192.168.1.2 and apply it to policy-map and drop if violation happens. I know I can use bandwidth limit but user may move to different port on the same switch. Maybe the only way to do this is on core? Any suggestions or opinions are appreciated.
