Hi John, I designed and evolved a network on the same sort of basis over time.
It started out with 2 3548 switches, then we added another (all daisychained via fibre) then when another was added I recommended they put in a 3550-12G to act as a core, they did this, and have added more switches to it over time. They have now plugged 5 switches in to the core, each with two uplinks in an etherchannel port group. If they need to add another switch (unlikely), I will suggest that they buy another 3550-12g and have redundancy in the core (one fibre pair from each access layer switch into each core switch). This also gives them the capability to plug another 5 switches in to the core. At the moment, if the core switch failed, all the other switches could be daisy chained off each other, so (IMHO) it is a good design fit for purpose. The 3550-12G has L3 capability, and is reasonably priced, although, unless there is some security or political reason, I wouldn't personally introduce VLAN's into your topology, not for 130 users. Having a look at some numbers (in the UK), I get an option that you could follow (making lots of assumptions about your requirements): All 3550 1 x 3550-12G 5 x 3550-48 (SMI software) 20 x GBICS Total, about $57,000 AUD, plus fibre patch cables, racking etc. Using 2950's didn't make it much cheaper.

The budget I have been given from my manager, would not pay for a family visit to McDonalds. However, this is the requirment (my product selection is below) * Provide up to 200 ports on the floor * 2 level building, with multi-mode fibre between level 1 & 2 * Level 1, has 70 users, 30 servers * Level 2 has 60 users * 2 subnets will be used in this office I suggested, that we use a single 4003 as the core, purchase a Sup III, 1 x 8 port GBIC module, 1 x 48 port 10/100/1000 module. We then use the GBIC's to extend to the 2 x 2950's on the floor above, and 2 x copper GBIC's to the 2950's on the same floor as the core switch. This solution, worked out to be around $100K AUD (australian $$). This was seen as far to expensive. Is there any other model of Cisco catalyst switch that can perform layer 3 routing, GBIC between floors and etc that could do the job of the 4003/4006 ? Or is there a better way of doing it ?
