VLAN and Switch Recommendation

We are in the process of installing a 20 Meg Metro-E connection and we need to be able to segment the bandwidth into 3 different VLAN's that should be completely separate for security reasons and be able to assign a max bandwidth usage rate per each VLAN.

First of all is this possible using 1 managed switch and would this be the recommended way to do it?

If yes, what is a good switch for this purpose?

Yes this is possible using one managed switch ( depending on how many users you will have). It can be done by use of policy maps. All new managed cisco switches have this capability. but I would recommend going for a gigabit switch. the type of switch also depends on your budged as they can be quite expensive.

Enterasys switches have great policy capability which don't require an external policy server.

Can someone briefly summarize what is a policy map and would I need to purchase anything else besides the switch.

Basically, I just want to use this switch to separate our internet connection into 3 different VLANs.  I don't need a lot of ports because each VLAN from this switch will then have it's own separate physical switch.

A policy map is a "tool" to provide Quality of Service (QoS). It allows you to limit bandwidth, allocate bandwidth, police bandwidth, shape bandwidth and set precedences.

then create a class map and match the traffic you want to affect (you can match many other types of traffic in a class map such as IP, VLAN, web, telnet, ssh...etc.)
then create the policy map, specify the class map, then specify the bandwidth you want to allocate to that specific class map.

the 3560 switch has this capability. The switch is also available with only 8 ports i believe.

Is this built-in to the 3560 switch?  Is it a web interface or is it some separate software that is used to create the policy?
Marius GunnerudSenior Systems EngineerCommented:
it is built in to the switch. Can be configured using CLI. I have never tried to configure it using the GUI so can't really say if it is possible or not through that.
