QoS speed limit 3750

Hi

im having problem with my QoS speed limit on my 3750 g12. Im trying to limit the speed on a port to 2mbit up and download with the following :

policy-map max2M

class allip

police 2000000 312500 exceed-action drop

interface GigabitEthernet1/0/2

srr-queue bandwidth shape 500 0 0 0

service-policy input max2M

I have tryed to enable and disable this command on the interface :

priority-queue out

but i still get full speed on my download (from the client)

I know that the following is working but then i have to force the interface to 10mbit, NOT good :

speed 10

srr-queue bandwidth limit 20

Hope any one can help me here ?!?

Re: QoS speed limit 3750

Hi Martin,

Whether this gig1/0/2 is uplink port of the switch or you connected your client on which your downloading from your server.....

Simillarly the policing is for the interface and also restrict your specified limit in case of only congension on that interface. Until the congension occurs, it will allow traffic upto the available b/w.

Rate if it does,

Hi,

your saying ? :-)

the port is connecting a client, yes.

I want to limit the speed on that port only, to 2mbit up and down, and not the uplink port to our core.

Try this.

Change to police 2000000 16000 exceed-action drop

Change both sides to 100 megabit

srr-queue bandwidth shape 50 0 0 0

I'm not a qos expert but I did similiar.

Re: QoS speed limit 3750

hmm ... how is this gonna work ?

srr-queue bandwidth shape 50 0 0 0

1000 mbit / 50 = 20mbit

Re: QoS speed limit 3750

I think you get the equation for bandwidth shape is

1/# = bandwidth result

So for a 100 megabit connection, 1/50 = 2 megabit

Maybe my config was different then yours, I dont remember.
