Bandwidth limiting 3550 -3560

I am trying to limit the bandwidth between a 3550 gig0/1 and a 3560 gig 0/1 connected via MM fibre. I want to restrict this connection to 10Mbps - any ideas

Re: Bandwidth limiting 3550 -3560

On the 3550 you can configure an egress and ingress policer on the port

policy-map QoS

class class-default

police 1000000 exceed-action drop

int g 0/1

service-policy input QoS

service-policy output QoS

The 3560 does not support egress policing via service policies.You can however limit the bandwidth with the interface command:

int g 0/1

service-policy input QoS

srr-queue bandwidth limit 10

Re: Bandwidth limiting 3550 -3560

Tried these commands but found problems as the switch would not take them, I have included the IOS versions and the commands that I have tried plus the options the switch will allow on the attached file. Any help would be much appreciated.

Re: Bandwidth limiting 3550 -3560

I forgot the burst size

so change the police command in this way

policy-map QoS

class class-default

police 1000000 10000 exceed-action drop

for this error

I/f GigabitEthernet0/1 class class-default requested bandwidth 1000000 (kbps) A

vailable only 750000 (kbps)

Under the interface configure this first

#max-reserved-bandwidth 100

Re: Bandwidth limiting 3550 -3560

We have setup the testbed as per the attached files.We have used Solarwinds Wan killer and Real time interface monitor to look at the traffic. It seems that traffic is restricted when going from 10.33.240.1 (3560) to 192.168.1.10 (3550) over the fibre link, but when sending data back the other way it seems that the 3550 is not restricting the traffic.
