Currently I have a few /24 subnets but I want to start breaking those off into smaller subnets so that each one of my customers can have there own subnet/vlan.  I've been searching around, and talking on some of the IRC channels and I've been told that I should purchase a 3550 as the 'core' and a few 2950G-48's for my 'edge'.

I need to be able to rate-limit both in and out at the edge to keep collocation customers from going over there limit.

Also, would I just trunk the port that links the 2950 to the 3550 and then just create that customers subnet as a sub interface on the 3550 and then setup a vlan on the 2950 from the uplink port to the customers port?  

I'm trying to find out the best way possible to do this and give me the ability to easily grow.  I don't want to be redesigning this anytime soon.  

I was talking to the head network guy at the datacenter and he didn't have much experience with the lower model switches but told me that I should ask and find out how well they will hold up to DOS attacks.  He said he used the 2948-L3 and it was a terrible switch.  

Thanks in advance
