Designing VLAN and Routing consideration

[scolombo]

I've been asked to design and implement a portion of an ISP's LAN.

The project is about a Housing LAN in which ISP's customers will put their servers.

the simplified schema is the following

|PIX535|-----|CAT 6513|------|CAT 3550|------------------

| | |

V V V

L L L

A A A

N N N

Each customer will be given one LAN connection to a departimental cisco 3524 switch, to this connection they can attach one or more server.

Each customer must have its VLAN.

Each customer may agree for a granted bandwith.

Each customer will be assigned an IP range

My questions are :

- I've thought of creating per-port VLAN for each customer , but I don't know how to route packets coming from outiside ( PIX535->CAT6513 ) to the correct VLAN

- Could the creation of per port VLANs pose any problem while implementing QOS ?

TIA

Try adding an msfc to the 6500.

The 6500 has got the MFSC. How can I set the two switches to have the traffic coming from the 6500 routed to the correct port of the 3500 ?

Each port of the 3500 will belong to a different VLAN but on each of them the hosts are on the same subnet

Let me know if this link is of any help;

Yes it has been of great help to understand how a possible configuration could be.

Regarding the examples , my situation is similar to the external DMZ . The only difference is that between the PIX and the final switch there's a 6513 .

How can I implement it

How can I implement PVLAN on 3550 ?

Here is two links on the edge 3550 switch protected port feature;

PVLANs are available on the Catalyst 6000 running CatOS 5.4 or later, on the Catalyst 4000, 2980G, 2980G-A, 2948G, and 4912G running CatOS 6.2 or later.

Better late than never I guest, check out the link on this page for 3550s.
