Vlan rate limiting

Hi,

I was wondering if a layer2/3 (e.g 3550 EMI) switch is capable of rate limiting effectively between vlans? We would like to setup a test network with a number of vlans, and would like each vlan to have varying bandwidth constraints (e.g Allow up to 256k to vlan 1, 10Mb to vlan 2 etc)to simulate connecting sites of different bandwidths.

Does anyone know if this is possible or have any suggestions on how to achieve this?

Thanks,

Chris

Re: Vlan rate limiting

Hi,

try Traffic-rate policing.

Here is an example how to set bandwith for traffic incoming to Fa0/1 to 20Mbps:

class-map match-all CM

match access-group 1

!

policy-map PM

class-map CM

police 20000000 8192 exceed-action drop

!

interface FastEthernet0/1

no ip address

service-policy input PM

!

access-list 1 permit any

Your requirement is more complex, I know.

And there is a limit service-policy command can't be applied to VLAN interface, I'm afraid.

But these URLs could help you:
