Policing in QOS

Currently i am having an issue where it seems like my Policing is not working correctly. I am using this on a input policy from My LAN to My WAN. What happens is the servers that match that ACL are only allow a certain about of bandwidth to push out updates to our remote sites but when they do push it bring those remotes site to a crawl. So is the policing total amout per interface or per flow ? ANy aisstance you could provide would be most helpful.

match access-group 157

Re: Policing in QOS

In this example it would not police per-flow.  It would police all traffic matching the class WINUP to 750Kbps.  You may want to investigate micro-flow policing on the downstream switch.


This link has some good micro-flow info:

Re: Policing in QOS

i didnt want to do per flow just wondering why we had a policer on that interface and it doesnt seem to be working right ...casue when those servers start a push they kill some of out remote sites the ACL its maps to is an Extended IP host ACL so it should cover all ports.it is also placed high in the policy

Re: Policing in QOS

When the problem is occurring try a 'show policy-map interface g0/2'.  This should give you and indication if the traffic in question is being matched by the WINUP class.
