I am currently a student working on a project that has me designig a network for a small business. So I was hoping that someone could suggest what switch(s) I should use from the Cisco product line. I am going to need approximatley 285 ports split up between 5 floors. So I am thinking I am going to need a combination of 24 and 48 port switches. network is 100Mbps. Some of those ports are going to be for Voip, going to need VLAN. I am new to this so not sure what information you need exactly. I also need a a gateway router that can handle VoIP as well. Any help would be greatly appreciated.
Thanks,

Hi Gerard,
Based on your diagram I would make the Switch on the 1st floor the core Layer 3 switch to remove the routing function from the firewall. A robust L3 switch can take this function on. All the edge switches on Floors 2,3,4,5 and should home run back to this switch. If it is possible for redundacny you can have 2 24 port L3 switches in the core and have redundant connections to both switches should one core switch go down. Looks like you have the 1st and 2nd floor sharing the same switch, if the cables are long enough this can be accomplished. Hope this helps.

Hi Gerard,
Looks good, your DMZ servers should connect behind the ASA instead since this will be your firewall. After that you should be good to go. Let me know if you need anything else.

Kevin,
It is my understanding that a DMZ is between two firewalls if I move it behind the the ASA how is it protected? Once again thank you for going above and beyond the call of duty. This project would not of been the quality that it is now without your help.

Kevin,
Just read that the ASA has an DMZ support function, from this I gather that it creates its own logical DMZ. If that is the case what model ASA would be a best fit for this network.

Hi Gerard,
An ASA5510 will suffice for this network. Here is a link that will have more information on the ASA's.
