QOS Police not working

[faizanelahi]

Hi All,

I need to limit the bandwidth on a switchport to 1 MB, ,for the same i have applied below commands

speed 10

srr-queue bandwidth limit 90 

Also, i created policy map and assigned it to switchport as below.

policy map 1MB

class link_1MB

police 1000000 8000 exceed-action drop

and applied this to interface 

int gi0/3

service-policy input 1MB

But still when i see my interface it is exceeding bandwidth which in result causing congestion in the network. Pls see attached image

Am i doing anything wrong here ??

Please help to resolve.

Try srr-queue bandwidth limit 10, for output.

For input, what's your class map criteria?  What does your policy stats show?  It's possible, interface stats show rate entering interface before the policer can drop them.

Hmm, your OP has service-policy input 1MB, and your policy_map.jpg has policy_1MB.  I.e. the two policy names don't agree.

Ok, your attachment shows no hits on policy.

What's the device and IOS version?

What's the ACL?

Please post the actual interface config, all it's supporting config, interface stats, and policy map stats.

Its still going beyond restricted bandwidth and effecting overall network performance.
