Vlan traffic bandwidth restriction

Hi All

Looking for some guidance on restricting bandwidth on a per vlan basis on either 3750 or 3560 switch.

We are soon going to have 8 vlans that are Layer 2 only and different contractors connected to each vlan.

From the switch we will have an uplink to an ASA and from there a connection to the internet.

We need to provide each contractor/vlan with bandwidth ranging from 256k to 2mb (bi directional) as they are going to pay for the bandwidth.

Any suggestions would be gratefully recieved.

Re: Vlan traffic bandwidth restriction

You could use an aggregate policer on the 3750.  Each physical port that participates in the VLAN could be a participant of the aggregate policer; therefore the total bandwidth of all ports would never exceed the configured rate.

An easier approach may be to install a rate-limit on the ASA that matches the contractor netblock.
