Need Help with QOS on a 3560 switch with 24-TS

[syedasifraza1]

Hi,

I'm new to QOS world and need a solution and understanding for the following scenario:

PC1 ------ SW1 -------- SW2 ------- PC2

All the ports are in the same vlan, the switches are both 3560 and their is no SVI created on these switches. There is no QOS configurations on any of the switches. Now i want to limit the traffic from PC1 to PC2 to 512 Kbps. Below is the configuration i have done to achieve this but i could not see any effect of the configuration:

ON SW2:

mls qos

mac access-list extended ABC

permit any any

class-map ABC

match access-group ABC

policy-map ABC

class ABC

police 512000 10000 exceed-action drop

int fa0/13 (Port connected to SW1)

switch port access vlan 100

service-policy input ABC

-------------------------------------------------------------------------------------

Now my problem is when i do the following commands, i dont see any numbers in the counters and even the access list counters are not increasing.

sh service-policy int fa0/13

Hi,

If IOS >= 12.2(25)SE then individual policers are only supported on SVIs.

Thanks Cadet,

The switch is running the 12.2 IOS version. Can you please suggest which IOS version should i use to accomplish this task? More over, can you please explain a little bit more on individual policers and the aggregate policers? i want to know if my configuration is correct or it need to be modified?

I would try using SRR. Start here , then here.

Thanks Florin for the valueable input, but SRR will not work because i want to limit the bandwidth to 512Kbps which is not possible with this as the pertage values for SRR are from 10 to 90 percent and on a 100Mbps port the minimum that i can set would be 10Mbps.

I'm looking for some thing which can help me limit the incoming traffic from PC1 going towards PC2 to 512Kbps. Any suggestions are more then welcome.
