Bandwidth policy on multiple ports

Hi,

I currently have an 3825 with only two ports.

This 3825 is connected to a fiber connection and makes an PPPoE connection for the subnet I got.

The second port is one of the ip addressess that I got assigned.

I want to control the bandwidth per ip address on this router.

How can I do that ?

Policy I normaly can set per port, but in this case all traffic goes over this port.

Is there a network module that supports policy based on bandwidth ?

I have a 9 port now but apparently it only supports TOS,.

Any ideas ?

You could write a policy-map to match on IP address and assign bandwidth this way. Something like:

class-map user1

match access-group 1

class-map user2

match access-group 2

policy-map BANDWIDTH-LIMIT

class user1

bandwidth 1000

class user2

bandwidth 500

access-list 1 permit 192.168.1.1 0.0.0.0

access-list 2 permit 192.168.1.2 0.0.0.0

You would then apply this service policy to your WAN interface. It is not very scalable though and it relies on you having static IP addresses assigned to your users.

As was mentioned in the original response you would use the service-policy command to apply the policy map to the outbound interface. You may want to look into this link for additional information.

This solves my issue.

The ip addresses behind are all static, so with the user and access list I can then also limit it.

Thnx

Hello

Can you clarify a few things -

You can classify on mac/host address or even on markings from each host.

What is it you wish to do?
Police ( meaning provides a given value and not let this host exceed or

Assign a % of bw which is adhered to when congestion is occurring?

Hi,

I am missing the last step.

How to apply the policy to the interface that it allows per static ip a limit.

I did the above, but missing one step to apply to the interface.

All info i find is for all data. not for one specific.

class-map user1

match access-group 1

class-map user2

match access-group 2

policy-map BANDWIDTH-LIMIT

class user1

shape peak 47000000

class user2

shape peak 47000000

access-list 1 permit 192.168.1.1 0.0.0.0

access-list 2 permit 192.168.1.2 0.0.0.0

this should limit per ip address the peak at 5Mbps but how to apply to one interface !.

As was mentioned in the original response you would use the service-policy command to apply the policy map to the outbound interface. You may want to look into this link for additional information.
